The Liteway Elementum Pack Ultra 50L is the Dyneema-fabric version of the Elementum 50L, built from Ecopak EPL Ultra 200 — a 67% UHMWPE / 33% Repreve polyester blend at 119 g/m² — trimming weight from the standard 665 g to 640 g while keeping the same 50 l capacity (37 l main plus 13 l external) and 12 kg load rating. The fabric swap pushes the volume-to-weight ratio to roughly 78 l/kg, a modest but real gain for the same pack volume.
Unlike the standard Elementum, this Ultra version offers four torso sizes spanning 40–55 cm, letting hikers dial in fit more precisely, paired with 3D-mesh padded shoulder straps for extra back ventilation. Organization closely matches the standard version — kangaroo/shove-it front pocket, two mesh side pockets — but compression runs top and bottom rather than sides only, useful for cinching a partially loaded pack. Positioned for multi-day trekking and thru-hiking at trip lengths of roughly three to five nights, it suits hikers wanting the Elementum's frameless simplicity with a lighter, more durable Dyneema-blend shell.
