I wear mine everywhere: working in the medical field, weight lifting, shooting, climbing trees bow hunting, mountain biking, swimming, wood working. I’ve stretched out two in the last year. One was hauling a +50 lb Pelican case across a few airports, I think the polymer/plastic handle is gripping enough it grabbed the silicon and stretched it. The second I noticed after doing pull-ups on a bar with a silicon like grip, also stretched it. Both times customer service came back quickly with a coupon code to order a new one. They’re silicone, I wear mine doing everything, they’re going to stretch/break. As long as the warranty keeps being good I’m happy with my purchase.

In fact, I bought a second one, the thin version, so I always have one on hand as I wait for a warranty replacement next time I wreck one.
