Arc'teryx Acrux 65 Backpack - 3900-4270 cu in

Arc'teryx Acrux 65 Backpack - 3900-4270 cu in description

Arc'teryx made the Acrux 65 Backpack with 4090cu in of waterproof storage and a low 4lb 3oz (regular size) weight for alpine climbers casting off on massive 4-day-or-more routes. Seam-sealed VaporTight fabric and a roll-top closure make the Acrux 65 backpack completely impermeable to any mountain storm. The lid, dual aluminum frame stays, and molded Binary Hippods are removable for your ultralight summit push. Pre-molded shoulder straps add to this Arc'teryx pack's comfort, but it's the ability to keep your sleeping bag and down jacket dry for five days straight that makes the Acrux a favorite. *Available for US shipment only.

Bottom Line: Bring the lightweight, waterproof Arc'teryx Acrux 65 Backpack on the five-day alpine assault you've been training for.

I was looking for a lightweight pack. Despite the fact that my old one is more than 15 years old, nothing was as light as it (Karrimor Alpinist), apart from the GoLite which looked too flimsy. The Acrux 65 was the next best, but is still 0.5kg heavier. When looking at the pack, it is surprising it is so light, given the large amount of heavy waterproof material. The closure is very waterproof, and the whole pack stayed dry during a snowy backpacking trip. The negatives are the narrow bottom of the pack, which makes it hard to fit a sleeping bag in across the bottom. Also, the rubberized inner surface makes it hard to slide things down to the bottom. It could do with a compression strap on the large top lid. The positives: lightweight (relative to the competition), very comfortable, and very clean external design.
