Hyberg ATTILA Lite

The Hyberg ATTILA Lite is a frameless ultralight backpack with 50 litres of volume, built from ALUULA Graflyte — a laminate made from 100% UHMWPE polyethylene that combines low weight with high tear resistance. In size M it weighs 590 g, which at 50 litres works out to roughly 12 grams per litre, a figure at the light end of the ultralight category, well below the weight of a conventional framed pack. The frameless build saves weight but shifts load transfer mostly to the padded hip belt with zippered pockets, which keeps the load closer to the body. A roll-top closure lets you adjust volume to whatever you're carrying, stretch mesh side and front pockets give quick access to a bottle or a layer, and the pack is hydration-compatible. The recommended 15 kg max load fits a lightweight-kit philosophy rather than heavy expedition carries. It's built for multi-day trekking and thru-hiking, where every gram on the pack compounds over the length of a trail; hikers used to a rigid-frame pack's load transfer will need to adjust once loads get heavier.
