I love the H20 tape I swim with a ancal fracture

Even works for a construction guy

Written by Sarah G. on 2nd Feb 2017

My husband has really bad tennis elbow in both arms from working in construction for 18 years. He has trouble straightening his arms. We tried another brand first because it was more available in stores but it was always peeling off within hours. Rock Tape H2O is going three days strong now and my husband says it's vastly improved his pain. I've used tape on my patella to help it track properly (tight IT band), and I've also noticed significant improvement. Staying put is essential.

Awesome Product

Had a shoulder injury from playing hockey and this tape helped me get back on the ice quicker than expected.

Rock Tape a hit at the Huntsman World Senior Games

Written by Dave Hunter LMT on 13th Oct 2016

Most of the athletes had not heard of rock tape. Used H2O Great product, stayed on longer, by far the best product for athletic applications as it will remain in place in extreme conditions, even in a Whole Body Cryrotherapy Chamber treatment. This product provides great support and stability. Great product to work with.

RockTape a hit at Ironman World Championship

Written by Stephen Black on 7th Oct 2016

Fabulous product! Tapped several athletes who raved superiority over all other tapes. Better stick, better control and overall improved performance. A must for anyone working with Athlete's.

Awesome Product

Written by John Burnham on 4th Sep 2016

I play hockey and we all know it's a sweaty sport. I tried the regular KT Tape and it's a good product but that won't hold under the pads under sweaty conditions. I was introduced to ROCKTAPE H2O from my chiropractor and this holds up 100% under the pads and made my shoulder and knee recovery a lot quicker. Great job to the staff who made this product.

Best tape around

Taped my knee for a half IM. Stayed in place the entire race. Great product!

Helps damaged knees

After surgery on both knees, one had residual issues. RockTape has helped reduce the pain during normal daily activities.

No Comparison to KT Tape

Written by John Burnham on 14th May 2016

I injured my shoulder and knee playing ice hockey. I used KT tape to help and its ok but it doesn't hold under sweaty pads. My chiropractor told me about ROCKTAPE H2O extra sticky and she ordered it for me. I used it once under the pads for hockey and it held in place after 90 mins of grueling practice. I recovered quickly, I'm hooked on it, recommend this to all athletes, and will continue to use this awesome product. Nice job and kudos to everyone who is involved in making this awesome product.

Stays on no matter what

Written by Richard L Wurzler DC on 9th Apr 2016

Have used this tape for triathletes, cyclists and runners and it works very well as it remains in place throughout the entire event. If it remains in place for a triathlete, it will be fine for nearly any use you can think of! The Rock Tape H20 is the by far the best product for athletic applications as it will remain in place in extreme conditions.

Nothing compares to Rocktape!

Written by Dr Brady Wyatt DC on 28th Feb 2016

In our busy office setting we don't have time for second best. When I tape someone I need to have everything work smoothly and quickly the first time. RockTape provides me the peace of mind I need as a physician because I know it is going to work and hold up against whatever challenges they're up against. DONT WASTE YOUR TIME OR MONEY ON ANY OTHER TAPE! We've tried them all, RockTape is superior in every possible way! - Dr. Brady Wyatt , DC Masula Chiropractic Neurology &Famly Wellness

Easily Customizable

Written by Dar on 19th Nov 2015

RockTape H2O is easily adjustable to any length because you can cut it to whatever size from a single roll al opposed to other brands that are in pre-cut shorter pieces. It has more stretch and as such does not provide quite the support as others. It also is stickier and once placed it stays, especially at the anchor points but more easily comes off where it is stretched and applied.

Stayed on through two intense swimming workouts

Written by Jen on 7th Jun 2015

I used RockTape for several months to stabilize my ankles, but found that even with professional application the tape still tended to come off after a few days of workouts and showers--I didn't even try to swim in it. This extra-sticky tape has survived four showers and two hours in the pool on one application. I don't think duct tape could have adhered better, and that's saying something. Highly recommended for any swimmers out there who need the stability this product might provide.

last thru water aerobics 3 tx a week

Written by Dr Dawn on 23rd Mar 2015

my mom loves this tape, last better than any other brands I have tried on her, which is many. She kept telling me the black was better, then I looked at the box and realized why. Doctors can learn from their mothers. Note she does not like the nearly naked girl on the box, so I took it out of the box for her to take home!!!!

Great tape

Written by Marty on 29th Apr 2014

This H2O tape is great. I have been swimming as a result of an injury I have and tape stays on 3-5 days just like they advertised. Love rock tape.

Great for people and Animals

Written by undefined on 8th Oct 2013

I use Rocktape quite frequently. I work with horses, I have a tendency to strain myself. I decided that I would go ahead and use it to help me rehab a Miniature horse who has very poor muscle coordination much less the muscle to do it with. I noticed an immediate difference she moved much easier and she moved more. I watched as she started quickly gaining muscle in her back and hind quarters and the transformation has been amazing! It just goes to show how well Rocktape really works. Not to mention it stayed on her for over a week.

The only company to buy from

Written by Edward Dudek on 3rd Sep 2013

This tape changed my life. It took care of my golfers elbow in such a way that I'm able to do what ever needs to be done. But the best experience is using this company,I wish all companies would sand by their product as ROCKTAPE did for me.

Superior to all other KT tape

Written by Dave Herman on 31st Jul 2013

Since we started using the H2O rocktape, the results have shown with our patient response. Patients are marveled on how long the tape lasts, and how much benefit the tape has for their aliments. Great product.

Great company!

Written by undefined on 20th Jun 2013

There was a small mishap with my order and Rocktape fixed it immediately, with no resistance whatsoever. Great product and will continue buying the best Kinesiotape on the market!

Triathletes Love it

I have been working with a Triathalon club and they absolutely Love the H2O tape. Many of them keep it on 5+ days. Thank you for this great product!

Where have you been all my life?!

Written by Rob on 15th Oct 2012

This product has greatly improved my mobility during recovery of my knee injury and has eased aches and pains related to my activities. I will always have a roll in my gear bag from now on.

Rocktape H2O review

Written by Tim Gill on 14th Jun 2012

I run in 5-10 marathons every year in very hot weather, and sweat a great deal. I always had problems with adhesion in the past with other inferior brands, but the Rocktape H2O is incredible! Thanks Dr Judy for the great info on a fabulous product!

Solution for a sticky problem!

Written by undefined on 25th May 2012

The product works well, but the tape does not stick as well to itself as it does my skin. I am a weekend athlete, far from young and this product enables me to keep on going!

H20 tape...only way to go for triathletes on or near event day!

Written by Allen Manison, DC, DACBSP, CCEP, CSCS, CKTP on 30th Apr 2012

I have been using RockTape for several years...since discovering that it is superior in many ways to KinesioTape. One shortcoming of most all kinesiology tapes is that they tend to not do well in water, particularly pool water. It's safe to say that Greg and his design team have hit a home run with the H20 tape... Nothing matches its stickiness and nothing holds better in water. I highly recommend this tape if you work with any athletes who are involved in water sports. Now we only need this in 4 inch tape and with some cool designs.

Stand Up Paddling

Written by CHIRO Tony Peters on 23rd Apr 2012

A great tape for Stand Up Paddlers due to repetitive movement of the shoulders. Great for the legs to help support balance too.

Best fit for my swimmers

Written by Cindy Doody on 19th Sep 2011

I am the sports massage therapist for a USA Swim level group in MA. I have been working with Rocktape in my practice on triathletes and pro cyclists for two years now. H2O stays on all weekend through the toughest meets.We really believe in it, and once the athletes feel the difference, they love it as well.
