This is the the only option for a legitimate, full coverage water flask sleeve available for a 32oz bottle. And it serves its function of protecting, but, the "soft feel" rubber used marked this thing kinda slick, it'll slip if your grip isn't strong enough, furthermore there's a flat section and I'm not sure where to align that flat... at the finger tips... At the thumb tip... Between the thumb and finger? I don't know. It's looks cool, it will definitely protect within reason. Really would prefer a different rubber though... Something less soft/silky.
This helps me to grip my water bottle so much better. It does make the water bottle a bit heavier, so that took some getting used to, but it's not enough of a change to drop my review to 4 stars. I'm very happy with it!
Silicone is easier to grasp than the insulated bottle itself, but you do have to have large hands if you want to hold with one hand. Helps keep the bottle cooler longer. Well made.
I was pleasantly surprised when this arrived, it's very thick silicone that does not feel cheap to the touch and covers the entire flask. I bring my flask with me EVERYWHERE that I go, hiking, yoga, my office job, and this will definitely keep my flask in good shape. Highly recommend!!!
