Great MTB pack

  • Familiarity:I've put it through the wringer

I recently purchased this pack upgrading from a smaller volume Osprey. First off, after years of riding with Camelbak packs...a friend suggested I try Osprey. I really like their packs.

This pack has just enough bells and whistles to make it really useful. The access to the innards is made simple by a couple well placed zippers. The 3 compartments make it really easy to carry everything I need for 2 hr, 4 hr, and all day rides. The main compartment (where the water reservoir is contained) is big enough for extra clothes. I use the left side secondary compartment for tools, CO2, pump and tube (for a spare). The right side secondary compartment is just the right size for food, etc. The helmet dock on the exterior of the pack is very useful.

Bottom line, love it.

Soooo many pockets...

  • Familiarity:I've used it several times

I picked this up for mountain biking, and it's a great size and fit for the task. Good amount of space for a full day out - water, extra layer, snacks, tools, etc. I think the 20L size is really a sweet spot for me in that it has enough room to carry a few extras if the weather is dicey without going overkill. Also, the suspension is great - the back panel is curved outwards slightly, so it leaves plenty of space for air to pass through. My gripe with this pack is that there are so many pockets that it can be hard to figure out where your stuff is. There is a large main compartment with water bladder sleeve, small sunglasses/ cellphone pocket, and two accessory pockets with mesh organizers for all your tools and smaller parts. The problem is that all of the pockets are stacked right on top of each other, with all of the zippers right next to each other. I find that I almost always end up opening 2+ pockets before I find what I'm looking for, just because everything is so close together.

All in all this is a great pack for its size - nice features and really comfortable for riding, I just wish they simplified the design and the zippers.
