Hyperlite Mountain Gear 5400 Porter

The Hyperlite Mountain Gear 5400 Porter is an 85 L expedition pack aimed at the most demanding multi-day and mountaineering trips, where heavy loads are unavoidable — HMG rates it for up to 27.2 kg. The body measures roughly 104 × 27 cm and is built from 100% waterproof Dyneema Composite Fabric (DCH150 on the body, DCHW on the bottom), so contents stay dry without a separate pack cover. At 1191 g, the Porter works out to 14 g per liter of capacity, a reasonable figure for an 85 L expedition pack — much of that weight goes into removable aluminum stays and a padded Dyneema hip belt with zippered pockets, both necessary for comfortably carrying heavier loads. Four ice axe loops and four daisy chains let you strap on external gear such as snowshoes or a tent. A five-year warranty signals HMG expects this pack to see repeated, long-term use in harsh conditions. The Porter is a choice for expeditions, not for weekend trips built around a light base weight.
