20L Lightweight Insulated Picnic Backpack

Compact yet spacious: 42 cm length × 19 cm width × 29 cm height. Weighs only 588 g — lighter than most 15L alternatives — yet delivers true 20L usable volume thanks to efficient cubic geometry and minimal internal framing. Holds 24+ 330 ml cans with space for meal boxes and reusable ice packs. Made from tightly woven, PU-coated 600D Oxford cloth; insulated with continuous 5 mm foam layer; lined with seamless, food-grade PEVA film. Cold retention relies on three integrated systems: foam thickness, heat-sealed liner continuity, and zipper seal integrity. All zippers are double-slider, water-resistant, and backed by fabric storm flaps. Back padding uses anatomically contoured EVA with laser-cut ventilation zones; straps are wide, cushioned, and anchored with bar-tack reinforcement. Side pockets are height-optimised for UK-standard bottled water; bottle opener is stainless steel and permanently mounted. Field-tested across English parks, Scottish hillsides, Welsh coasts, and Northern Irish trails — performs reliably whether carried for 15 minutes or 2 hours. Care is simple: empty, invert, air-dry — no special cleaners or drying racks needed, supporting sustainable, low-maintenance ownership.
