<b><p>Silicone Boot Sleeve Protector for 20oz, 26oz and 30oz Yeti Rambler Tumblers</p></b> <p>Add protection and peace of mind when taking your drinks on the go. Made of 100% food grade silicone and custom molded for a skin-tight fit on both 20oz and 30oz Yeti Rambler tumblers.</p> <p>This sleeve offers plenty of shock absorption and insulation with the 2.5mm sidewalls and 4mm base. Eight diamond shaped footpads add skid control and traction. With all this padding, slamming your drink down on glass or countertops won't be an issue anymore.</p> <p>The exterior surface is treated with a matte texture to enhance grip. So take your tumbler on your next adventure to the beach, park, lake or mountains. The enclosed design allows it to double up as a drinking cup.</p> <p>Although dishwasher safe, hand washing with mild soap and water is recommended to avoid water spots. Can be conditioned periodically with a spray protectant such as 303 or Mother's.</p>
