Additional Information

This versatile backpack is built to go light on routes from Fitz Roy to Chamonix, but willingly expands when you need to overstuff.

Designed for one- to two-day speedball ascents in places like Chamonix and Patagonia, this streamlined yet highly versatile climbing backpack has everything you need, but absolutely nothing more. It features an integrated, asymmetrical spindrift collar that opens wide and closes in a single motion for fast packing. A secondary collar protects your gear from ugly weather, allows serious overstuffing and holds gear securely when the pack is hanging at belays. The removable frame sheet, made from a lightweight aluminum rod and covered with mesh, provides support for weighted loads and moves with you as you bend and flex. Ergonomic shoulder straps (with load lifters) match your torso’s contours for 24-hour comfort, and the hip belt has removable pads for simplicity. Four rows of exterior daisy chains provide lashing options for a rope, helmet and pad; ice tools attach via an integrated buckle and tool pocket. Other details include compression straps to carry skis and cinch down loads, an asymmetric profile for elbow clearance and a zippered pocket on the lid for quick access to small essentials. Made from lightweight yet durable 6.25-oz 210-denier nylon double ripstop and 6.05-oz 400-denier nylon ripstop, and lined with a 1.8-oz 40-denier nylon double ripstop with a polyurethane coating and silicone finish and 200-denier polyester.
  • Lightweight, bomber, tear- and abrasion-resistant nylon ripstop
  • Asymmetrical spindrift collar opens wide for easy packing; drawcord simultaneously cinches collar and closes lid for a secure seal; additional spindrift collar deploys to protect your gear when you’ve overstuffed your pack
  • Aluminum-stay frame with tensioned mesh center gives pack structure and helps support heavy loads, but can be removed for lightweight pursuits
  • Hip belt has adjustable pads that can be removed to create a simple webbing hip belt, or you can remove the entire hip belt for ultralight travel
  • Center sheath ice-axe carry system accommodates a wide assortment of axes
  • Daisy chain on front panel provides lashing options; compression straps on sides help manage different size loads; zippered pocket on lid offers easy access to small items
  • Available in two sizes: S/M and L/XL
  • Body: 6.25-oz 210-denier 100% nylon semi-dull double ripstop and 6.05-oz 400-denier 100% nylon ripstop. Lining: 1.8-oz 40-denier 100% nylon double-ripstop with a polyurethane coating and silicone finish

Rated 5 out of 5 by from great design really like the curve of the back, husband said it made him have better posture. great size for day hikes, liked the closure. no external pockets, but was not a problem for us since we had external pockets on my backpack for frequently accessed items like water bottles,

Rated 5 out of 5 by from Perfect for its job I have seen some mixed reviews about this bag, so let me clarify one thing. This bag is for climbing and outdoor use. I don't think Patagonia ever intended this bag for anything other than technical alpine and rock use. So, with that in mind, this bag is perfect. A great combination of simplicity and features. It is completely streamlined, comfortable, and carries well. One major gripe many people have with the bag is its durability. To that point I say would you carry a stiff, bulletproof bag up a mountain? There is a great balance of weight and durability that I think Patagonia has nailed. Good job.

Rated 4 out of 5 by from Almost 5 stars... This is a great climbing pack for grade III and IV climbs. I also find myself just using it as a crag pack as well. The only flaw that I have is that the outer material is anything but durable. My friend's pack ended up with a few small tears on the first trip with the pack, and my own ascensionist is showing serious wear and I will likely see some small tears soon as well. All in all, it's a great pack, but a serious climber would wear this bag out in a few months, it's simply too thin.

Rated 4 out of 5 by from Great Pack But Missing 1Thing Pack is comfortable, light and has some great features but the biggest downfall is the lack of a key clip in the top pocket. I struggle to understand the rational behind that.... I am going to take one from an old pack and sew it in.

Rated 5 out of 5 by from All purpose packing I traveled Japan with this pack-very lightweight and stuffable, only drawback was lack of waterbottle holder.

Rated 3 out of 5 by from Good Pack with Room for Improvement Love the light weight and the way the pack fits with my body movement. It's just big enough for an overnight alpine rock climb if you pack it light. As a day pack for light/fast single day push, I think it's pretty well suited. That said, I have a few thoughts for improvement: 1. A hydration bladder sleeve. Yes, it would add a little weight, but would make it so much more functionally easy to pack. At least a little hole for poking out a water tube would be nice. 2. Better padding on the lower back or slightly different shape. My upper hip/lower back bones were kinda raw after 2 days and 16 hours of climbing. And...I didn't wear it for the actual climb itself, just the approach portion.

Rated 5 out of 5 by from The perfect overnight pack. I first used this pack on an overnight alpine climb in the eastern Sierra. I was able to carry all the gear required for an alpine ice climb, including ice axes, crampons, rope, protection, sleeping bag, food, water, clothes, etc. I will purchase the 45 liter version for work.
