On an extended weekend alpine ascent, when every ounce of weight and versatility is scrutinized, the Arc'teryx Khamsin 50 is a well balanced mid-sized designed that traverses the requirements. Loaded with alpine features and highly modular, this pack can be extended to deliver a monster payload, and then stripped down and compressed for light forays, or a summit bid. When fully loaded, the V-frame suspension, removable aluminum stays, removable hipbelt with thermoformed hip pods, removable hip belt gear loops, removable dual density framesheet, and removable/extendable lid pack a whole lot of carrying comfort. Strip it all down, and it converts to a summit pack with just the necessities to tag the top.

Our big mountain pack. Trek to basecamp, and then strip down for the summit. Hip belt, frame sheet and lid are removable, and the pack can be compressed to the body for stable, quick runs.

Sized for climbers who want all their gear inside the bag, the Arcteryx Miura 50 Backpack keeps your rack organized during a full day of ascents. The front side design zips completely open to provide quick and easy access to your quick draws, rock shoes, and an array of nuts and cams. The bottom of this convertible pack is designed to stow the Arcteryx Pali rope bag, and there is plenty of space left over for a double rack of gear, hydration bladder, lunch and outerwear.

Versatility, a women's specific fit, and surprisingly large capacity for its weight (only 4 lbs. 9 oz. in medium), the Osprey Women's Ariel 75 backpack is an excellent choice for climbers and backpackers who enjoy multi-day trips but want to keep the weight to a minimum. The recommended capacity of the Osprey Ariel 75 women's backpack is in the neighborhood of 40 lbs. so the suspension and harness need to be solid. Coined the AirScape suspension, it consists of peripheral 7075 AL rods, an internal HDPE framesheet with single aluminum stay and a covering of ventilated nubbed foam and mesh grip. This covering, or backpanel, provides superb contact yet still allows air to circulate. Connecting to the suspension, a women's IsoForm custom moldable hipbelt and IsoForm shoulder harness with dual density foam and Spacer Mesh surface evenly distributes the load. Most women find that the harness and hipbelt that comes with the pack is the correct size for them, but other sizes are available for an exact fit. Regarding the custom molded hipbelt, contact Osprey customer service at 970-564-5900 for molding instruction upon delivery of your pack. An overall key feature of the Osprey Ariel 75 backpack is its versatility. For those monster loads into base camp a stretch woven front pocket offers extra carrying capacity when the main compartment is stuffed. And then for go-light day trips from camp, the top pocket mates with the hipbelt to make a terrific lumbar pack. The Osprey Ariel 75 women's backpack is also Osprey Excessory compatible, meaning a choice of add-ons can be installed to further boost the backpack's versatility and capacity.
