The Ultraweave 23L Backpack is an extremely capable and technical offering from and wander. Perhaps best deployed as a daypack, the style is constructed from a patented polyethylene fabrication called UltraWeave, a high-density waterproof fibre that boasts a truly exceptional strength-to-weight ratio. The 23 litre capacity of the main compartment offers more-than ample space for a day's worth of gear, equipment and fuel, and there's an external organisational pocket on the top lid to keep essentials segregated.
