Cold Heat Resistant Cup Sleeve

Engineered for versatility in variable UK environments, this cup sleeve combines thermal resilience with ergonomic portability. Constructed from elastic diving material, it offers balanced stretch and recovery across all five size options: 15.5 × 6.5 cm (420 ml), 18.5 × 6.8 cm (550 ml), 19 × 8 cm (750 ml), 21 × 8 cm (1000 ml), and 23 × 8 cm (1500 ml). The rope strap is securely anchored with reinforced bar-tack stitching, and the soft handle zone is subtly padded for comfort. Interior surface is finely textured to prevent bottle slippage, while exterior remains sleek and wipe-clean. Weight ranges from 45 g (smallest) to 65 g (largest), making it among the lightest functional sleeves available for its capacity range.
