Exposure 66

When I went to the North Cascades last summer for a few days of climbing I was damned if I would bring by heavy Gregory pack, and yet none of my smaller packs was big enough to carry all my gear. So I broke down and bought the first new multiday pack I've purchased in many years. I wasn't sorry. This pack is lighter by almost 3 pounds than my Gregory, yet at 4,200 cubic inches, was big enough to carry several days worth of food and gear. It carried extremely well. I love Osprey's belt cinching mechanism. It has a minimum of extra straps and things to flop around and catch on things. Having the compression straps on the back also allows you to attach bulky stuff without having it on the sides, where it gets in the way while climbing. And the price was right.

I bought this pack last year for Shasta's Hotlum glacier and it packed well for three nights on the glacier! It is super light and still sturdy with the seams stretched to fill it up. The tool holsters were great for pulling out my hammer when things got steep and the gear loops on the hip belt are awesome when a pack this size makes access to your harness gear loops difficult.
I don't know how to vote, but I give it a 5/5!
I'm between a medium and a large on most things and the large was definately too big so you might need to go down a size if you're inbetween.

The Exposure 66 is a great pack. It fits perfectly, is pretty light, and has minimal bells and whistles (a plus in my opinion). I have used it on everything from 17 hour alpine climbs to 3 day backpacking trips. Get an Exposure 66 and you will be happy.
