Hyberg ATTILA ULTRA

The Hyberg ATTILA ULTRA is an ultralight hiking pack built from Ecopak EPL Ultra 100X — a blend of UHMWPE fibers and recycled polyester — aimed at multi-day thru-hiking. Depending on size it weighs between 595 and 615 g and holds 46 to 50 litres, a weight-to-volume ratio comparable to lighter framed packs of half the capacity. The back system adjusts for a torso range of roughly 38–58 cm and the hip belt for a waist of 77–115 cm, giving it a reasonable fit range across body types. The fabric is highly water-resistant, the roll-top closure keeps contents dry through ordinary rain, stretch mesh side pockets pair with elastic bungee cord for lashing extra gear, and drain holes prevent water pooling inside. An adjustable chest strap and padded hip belt with zippered pockets keep loads stable up to the recommended 15 kg. For treks measured in weeks, this is a balanced compromise between very low weight and a usable back system — the recycled polyester content adds a bit more durability than a pure Dyneema build.
