Thanks for your review, Daniel!
United StatesGreat string
Gives just the right amount of spin. Holds tension well. Comfortable for a poly.
Velociti Sporting Goods
Thanks for your review, Trent! We're glad to hear it.
United StatesScrumptious Pasta
Give them a hand, folks! These guys are trying to be kind to the planet with relatively rapid decomposing string. It plays as a medium-soft copoly in the mains with natural gut crosses at 45#. Pocketing is good with average spin generation. Appears to maintain tension pretty well after 3 weeks of 3.5 NTRP doubles and singles play. Definitely worth the investment. Hopefully, the string industry will get on the eco-friendly bandwagon. In the meantime, give your bucks to Velociti Catalyst!

Thank you for helping spread the word, Christopher! We're so glad you're enjoying playing with Catalyst.
Great Product!
I love playing with Catalyst. Environmentally friendly tennis products are hard to come by, so I was happy to hear about a biodegradable tennis string! Not only is this string good for the environment, but it plays well. It's the perfect step between a hybrid (synthetic gut x poly mix) and a hard poly. It's a polyester string that gives you the pop you need, while not feeling too rigid. If you're looking for an afforable, enviornmentally friendly, and great quality string, Catalyst is it!!
Great String with Awesome Environemental Benefits
Protecting the environment is really important to me, so I thought I'd give this product a try. I really enjoyed how this string felt on my racket: good spin and control. I'll definitely be telling all my tennis friends about it!
