Stretchy Diving Cloth Bottle Sleeve

This cup sleeve is crafted entirely from premium elastic diving cloth — known for its durability, flexibility and tactile comfort. Dimensions range from compact 15.5 × 6.5 cm (suitable for 420 ml bottles) to large 23 × 8 cm (fits 1500 ml containers), ensuring compatibility with popular UK brands like Chilly’s, S’well and Hydro Flask. All sizes feature consistent material thickness and elasticity. The sleeve includes a fixed-position rope strap with reinforced stitching at stress points, offering secure grip and long-term wear resistance. The outer surface is smooth and low-friction, while the inner layer remains soft and non-abrasive to bottle finishes. Cold and heat resistance allows safe use with chilled beverages or warm drinks, and the lightweight construction (45–65 g) makes it practical for everyday carry.
