Duluth Trading Silipint Rocks Glass

Leave it to Duluth to pour on the functionality! This Silipint® Rocks Glass is as flexible in shape as it is in utility. The exterior is buffed to a glass-like finish, yet it’s flexible enough to fold into a pocket – ready to tackle challenges no regular glass ever could. Made of 100% food-grade, FDA-approved silicone, it won’t break, crack, chip or fade. Emerges unfazed from freezer, microwave and dishwasher, too. Even insulates so cold drinks won’t sweat and hot ones won’t sear your mitts. We’ll drink to that!
