The Cotswold Aquarius Brew Tube System Attachment is a modular addition to the RS335 Rucksack, designed to expand carrying capacity without increasing the rucksack's overall footprint. Each tube attaches neatly and securely between the front and side pockets of the RS335 Rucksack, and is available in two sizes. They feature a heavy-duty, wipe-clean base and a dual-pulley opening system for fast, easy access. The smaller tube is suited to pop-up tubs, small flasks, and compact brew kits (including 110g gas canisters), while the larger tube comfortably fits a standard C500 gas canister, burners, mugs, and other essentials. For such a compact addition, these Brew Tubes help keep you organised and enable you to pack up quickly when the time is right. - Small: 270mm x 90mm - Large: 270mm x 130mm
