I love using Masterline ProLocks, however I always have to keep 1 or 2 pairs as backup. I usually break/rip the strap on 3-4 gloves each year. I am a C+ skier and usually hook up hard right out of the buoy, which is generally where I am when the strap breaks. The first time one broke, it actually ripped the stitching at the wrist out of the strap. That happened twice, but every time since then the strap has literally ripped in the middle. Usually this happens within the first 10 sets with the gloves. I typically have no issues with Masterline replacing them as a warranty item, so I'm not really complaining here...just interested to see if anyone else has experienced this.
