Continuing its legacy as the world's most popular string, Prince Synthetic Gut Duraflex continues to be the top selling string through the years. Featuring a classic solid core with outerwrap layer construction, this string provides all around performance for players. Synthetic Gut Duraflex is named for the aramid fibers running along the outer layer of the string. This aramid fiber causes the string to play slightly stiffer and with a touch more control compared to Prince Synthetic Gut Original, while also increasing the durability due to its high strength characteristics. Providing consistent performance for a number of years, this string remains popular among players of all levels and styles. The solid central core helps to provide tension maintenance, while the outerwrap helps to both soften the string while providing some extra durability with the addition of the aramid fibers.
Construction: Monofilament nylon core + outerwrap w/ aramid
Color: White, Yellow, Gold, Black, Blue, Purple, Platinum
Gauge: 15L (1.35mm), 16 (1.30mm), 17 (1.22mm), 18 (1.17mm)

Tennis Express Reviews
The sensation when I hit the ball with this string is unremarkable. I have control, direction, and feeling upon contact that produces high performance in my game.
Nice String & Price
Does what it says and is quite durable, especially if you hit with maximum spin on strokes & serve.
The best explanation would be that it performs to the price. I tried it in a Hybrid with Lux on the mains and the strings started to slip and ended up in their own place. Had to constantly adjust the strings during play. Comfort is the only + point.
This was just plain bad. I bought the exact same strings from sports authority and they lasted more than twice the time.
Good, balanced string
Prince synthetic gut isn’t the flashiest string out there, nor is it the latest and greatest. However, it is still one of the better synthetic gut options available. It is a good, balanced string that is suitable for all types of players.
Very nice durable strings. I used it with the kevlar mains and the combo yielded awesome feel and durability. Highly recommended for the price.
Prince Synthetic Gut Duraflex is the only string I keep on hand for my stringer. Good durability, good playability, all at a reasonable price
Prince Synthetic Gut Duraflex String
Give a compact hit and keep you from hitting it out.
Gary L Freeman
Works for me.
I use the 17 gauge. I get alot of spin even though I have a compact swing. I feel the smaller gauge gives me more control and at 53 years old I need all the help I can get. The string seems to last quite a while depending on how often I can play.
PRINCE SYNTHETIC GUT
Always a reliable string, good feel and power.
Prince sythentic gut w/duraflex
I have been using this string for several years now. I have found it to be a great combination of durability and feel for the cost.
Prince synthetic gut
Im a USPTA teaching pro and also was USPTR. 30 years experience and I would humbly say this string is excellent. I would highly recomend it to anyone at any level.
Great Job Prince!! Brad
Have been using this string 16 or 15G for almost 20 years. Consistent all-around string with great price.
Synthetic Gut Duraflex review
Works great for any type of player. You will truly be satisfied.
possibly the best synthetic gut
There is a reason this is the most popular synthetic gut. It plays well, is durable, and is easy to string. I like is as a hybrid with other polys.
I use this as a cross string with MSV Focus 1.18. It is extremely durable and holds it tension very well.
Prince synthetic gut duraflex
I recently purchased several sets of the Prince synthetic duraflex strings for the local boys high school team which I coach. I have always liked these strings for their durability and playability, and the boys that have used these seem to be satisfied with their performance.
Beneficial for strong topspins and serves
When I purchase the Synthetic Gut Duraflex by Prince, it was the best synthetic gut Ive ever played with. The pattern on the strings had allowed me to generate more spins on my forehands & backhands, my volleys were nice and clean. And I felt like I could get the extra pop on my serve that I was looking for. I recommend these strings to juniors who want to better their game. The only down side to the strings are that they have to be straighted out a lot, since the strings tend to shift when hittng a strong shot back. But overall, best synthetic ive played with
There is a reason why this is the best selling string ever
Very arm friendly string and you just cant beat the color. In close exchanges at net I have been told that they loose the ball for just a split second in my stringbed. The strings perform very well but have a little bit of movement, and holds tension pretty well. Great as a full bed or for a hybrid
Gary L Freeman
I am a 3.5 player and have been using this string for a while. The 17 gauge gets a good bit on the ball and I can get alot of topspin. It does not seem to last as long as the 16 gauge but the added spin I get makes it worth it. The syn gut allows me to feel the ball even with my tennis elbow problems.
Although the string is durable I have noticed arm pain since switching string however to be fair I also have a new racquet which could also be contributing to the issue.
Prince Syn. Gut
String has performed very well. It enables me to get a bit more bite on topsin shots and its durability has been surprisingly good for a 17 gauge.
As good as advertised
Good feel and control, maintains tension well. Very comfortable.
Prince String Comments
I have used the Prince synthetic duraflex for a couple of years. For some reason lately, the strings are starting to pop after approximately 5 matches. I continue to use them due to their playabilty & control. Is their any reason why this has just recently started happening. I usually play one match a week & and play at a 4.5 level.
Durability not as advertised-
Prince Duraflex is touted as very durable. It is reasonably durable for the price, but Ive found it doesnt hold tension well or last as advertised...
Just what we needed...
The strings are exactly what we needed...great customer service!!!
Nothing Better for Price
I string my own racquets and used to use this string exclusively for my Head Radicals. Switched to Vockl V1 Classic and the strings were just not right for those, so I tried a multitude of more expensive strings. Ended up with hybrids. Went back to the Radicals and started using NRG 17, which are super strings but break too quickly and cost 4x the cost of these strings. So, I am back to the Duraflex and notice very little letdown from the NRG. Though not as soft, they last and have good pop. Only gripe is they do move around alot. So what.... Glad to be back!!!
Perfect delivery and product - nicely done!
Gary L Freeman
Good For Me
I have used this string for about a year now. I am a 3.5 player with severe elbow problems. Since I do not break strings much the 17 gauge helps me get more spin. This string is gentle on my elbow. After a couple of hours it will start to move a little but not bad. The low price is a plus.
Great string, just durability issues.
Pretty much your average synthetic gut but I almost always find myself going back to this string. Great pop and very easy to string as well. Durability is a constant issue with this string however..I break them in about a month.
Great feel...durable...will purchase again
prince syn gut
found the string to perform fairly well, though its does not have the bite as rpm blast or luxillon savage or spiky sharky by kirschbaum for topspin, but for the price its definitly the best choice
These string had a great pop,and unique spin to them. Color and gauge choices are huge. I highly recommend these strings to any mid to high level player.

I must say Tennis Express is doing an excellent job keeping my small tennis stringing business supplied.
My orders are filled efficiently and correctly with no shipping charges and great prices on quality strings.
Thanks to the staff and keep it coming!

Great GUT and great buy!
It was a nice gut and playing great for speed shots
Good syn gut at a reasonable price
Mains: Poly, Crosses: Prince Syn gut - Plays great! I get better feel and almost the same performance as a full poly bed.
Full Prince Syn Gut - Also plays pretty well. Has nice pop.
Synthetic Gut Duraflex
As always, the merchandise that I buy from you is everything its advertise to be. Prince Synthetic Gut continues to be a top line string as it has for many years.
17 Gauge Syn Gut
String had great feel! Didnt take long for it to break unfortunately.
Prince Gut duraflex
Feels ok when playing. What I did not like is the durability. After 6 sets they broke.
The synthetic gut duraflex that was used to string my new has been an excellent choice by the stringing tech!
Synthetic Gut Duraflex
I bought it for my son and he is really enjoying this string. It takes the vibration away and create less shock to the wrist. Thanks to Tennis express.
Synthetic Gut Duraflex
I am very happy with the Synthetic gut. It gives me both power and control.
THESE STRINGS ARE KILLAH
I LOVE THEM AND SO DOES MY
WILSON BLX PRO LITE RACQUET !
I recently ordered this string due to the cost, which was extremely inexpensive. I was happy with the string’s performance and overall ability to generate spin. I am a 4.5 player who is looking for more spin on my ground strokes. I discovered this is an older type of string that has been around for a long time, but it is still a good product. If you are looking for a synthetic gut that will last a long time it is a good option. Tennis Express is excellent on customer service, no issues regarding shipping and processing.
Got great advice from sales person. Delivery went very smooth
I will be using Co. again for future orders. In fact I already have. Thanks so much!
Very responsive string. Can provide some serious topspin and nasty slice.Very comfortable and easy on the arms.
Fantastic Basic String
I personally do not use this string at the moment but I string plenty of peoples racquets with it. I used to play with Prince Syn Gut mixed with tournament poly and I played plenty of fantastic matches with it. Everyone seems to be satisfied with Price Synthetic Gut and it provides the best performance for the price. Great string for all players.
Great strings for the price! I had it strung in my new Dunlop 600 lite Biomimetic racquet and they performed great. My ground strokes, serves and volleys were crisp to say the least. I would recommend this strings and dont be fooled by the price.
I used this in collaboration with Tourna Black polyester, works well and adds nice touch to Hybrid combinatio.
I really the responsive feel and sturdy construction.
Easy and fast
The racquet is all that I expected it to be.
Gary L Freeman
The Prince syn gut has been easy on my elbow. I have very little soreness when using this string. The 17 gauge does have more feel to it than the 16 gauge.
Michael T. Perkins
Good feel very plastic in rebound, had the strings loose to reduce should shock and it works well. shot need to be controlled as it is very easy to overhit.
Consistent string, a little expensive
I tried this string in the crosses with Solinco Barb Wire. Performance was good, but found no difference from the Solinco Pro-Stacked that was half the cost.
I have been playing for about 7 years now and just purchased my second racquet. I chose these strings because they were Prince and Purple. They seemed to offer what I needed. Spin and Feel. I was seriously lacking the spin before and have had to relearn how to hit due to the increased performance of the strings and racquet.
I love these strings, but am very new to all aspects of racquet buying. My first one was off the shelf and prestrung, so I had no decisions. I have played with string claiming more spin, but due to the racquet and tension was never impressed.
These strings impressed me, but Im a rookie.
Im very satisfied with the product and I didnt expect that you were going to encore the raquet , I though you were going to charge for that.
Great all-around string
I always use the Prince synthetic gut duraflex 16g string. It is durable and provides a good perfomance. My teen uses this string on his Prince racquet in varsity tennis and loves it.
Synthetic Gut Duraflex
Excellent strings! Tennis Express very prompt in product delivery!
Prince Synthetic Gut Duraflex
Most popular string in the world for good reason. Best value string with good playability and durability. Go to string when in doubt what to put in a racquet. Great value.
Prince 17 gauge synthetic gut is always my go to. Excellent durability and performance every time.
prince synthetic gut duraflex string
I really like the feel I get with these new strings
I seem to have more power & control than with my others that I was using. Very happy with them.
Good Feel String
I have tried different strings since I started playing tennis last year but the feel & durability was not satisfactory until I tried duraflex. I would definitely recommend this string for all recreational players.
Thanks. I got what I paid for.It was fast and easy.
45 Minutes and Broken String
I just bought a racket for my son and had it strung up. Within 45 minutes, he popped the strings. Paid extra to do a hybrid ... definitely not worth it. Have restrung it myself and so far so good.
I have been using this string for quite a while now. My elbow does not hurt now. My control is good.
All works good
Good service as well
Perfect Midle of the Road String
These are a perfect middle of the road string. They dont do anything specifically well, but they do all things averagely well. Theyre a great bang for you buck! Also, they play a little crisper than multifilaments which I prefer for drop shots and volleys, are little bit more durable, and dont fray.
Prince Syn. Gut
This string is good if you dont hit with a lot of spin because it loses tension very fast. But overall its pretty decent in a hybrid stringing and its good on the arm.
noorul wase ansari
I was very pleased with the service and I will go back again.
PRINCE STRING ROCKS
Only the word Perfect is near to decribe the good service your store gives.
Prince Sythetic Gut Duraflex
Recently purchased the Prince Blue LS 110 raquet and chose the Prince Synthetic Gut Duraflex string. All I can say, great match. I am very happy with its performance and so is my doubles partner.
