I’ve been using the 35 L version for most of my alpine missions in the Alps since February, and I can say that this pack is excellent. However, I do have one big qualification: This is a highly-specialized pack made for fast and light alpine mountaineering. It is not a backpacking pack or a cragging pack or skiing pack. It can do those things, but it is definitely a mountaineering pack first.
The 35L is just the right size for day excursions, and I think will handle multi-day outings just as easily. Though there are a couple of niggles — the top pocket and the tool handle attachment — this is a solid pack for the money ($179 Cdn MSRP). It is very comfortable, carries well and is easy to get into: I can live with the top pocket, and an extra dollar or two will you buy two velcro tool holders
I've been growing very fond of this pack. It can be a great option for weekenders or gram conscious backpackers who are dialed in with specific gear. Though I haven't used it in the winter yet, I look forward to taking it out on a overnight or ski specific trip, when the opportunity allows.
The Patagonia Ascensionist is a frill-free but intelligently designed pack that’s low on weight, high on comfort, and ideal for fast-and-light adventures
As pure a climbing pack as I’ve ever tested, the Patagonia Ascensionist 35L earns the Best in Class award for this season and sets a new bar for alpine backpack performance. The Ascensionist is easily the most versatile pack in this season’s tests.
