The Liteway Gramless Pack Ultra 35L is the lighter sibling of the standard Gramless Pack, built from Ultra 200X fabric (67% UHMWPE/Dyneema fibers) instead of Ecopak. That swap brings weight down to 390 g at the same 35 L capacity (28 L main body plus 8 L in external pockets) – a ratio of roughly 11.1 g per liter, among the best in the frameless-pack category.
The fabric is rated highly water resistant, the main compartment closes with a roll-top, and a kangaroo/shove-it front pocket gives quick access to a jacket or map, while two stretch-mesh side pockets and side-only compression straps handle bottles and load stabilization. The hip belt is removable, so users can shed further weight when they don't need it, and the pack is hydration-bladder compatible.
Liteway targets it at multi-day trekking and ultralight thru-hiking on trips of roughly six nights or more, carrying up to 12 kg. This is a pack for experienced ultralight hikers with an already-dialed gear list rather than anyone needing a frame or a heavily padded hip belt.
