The Ariel is the tough twin sister of the Aether designed specifically for active female mountaineers and back packers. This sack is designed to give excellent support while carrying heavy loads. It has been updated with Lightwire which keeps the pack longitudinally rigid, transferring weight to the hips and allowing load transfer as you move about. The Airscape Ridge Moulded back panel not only provides support but offers good ventilation too. The IsoForm C4 hip belt is also women specific and moulds to your body shape over time with small zipped pockets on it, ideal for snacking on the go. This pack has three areas of access so you can get to your stuff easily and has useful stretch mesh pockets on the front and sides for bottles and a place to keep the waterproof handy. See below for the full feature list and you'll see what a cracking bag this is!
