I did a lot of resesarch. This is an amazing jacket. The warmth / weight / packability / cost ratio is pretty ideal. As a rock climber, I needed a technical belay jacket to keep my girlfriend toasty warm. I picked it up for her in red - her favorite color. She now wears this jacket everywhere; from the city to the camp to the crags. Once in a while she gets poked with a feather on the inside; that's 'cause the jacket is so nice and warm, in town she wears it with only a t-shirt. It seems MHardwear(and my girlfriend) both run a half size small. I bought it in XS; my gfriend is 5 foot 1 / 107 lbs. This is the one.

Good news: Decent weight (versus competing alpine / climbing backpacks); Decent fit (for climbing / hiking / traveling); Handles a lot of gear. Bad news: Experienced durability issues (had to return to store); Color is subjective. As a rock climber / alpinist / traveler, I research gear before purchasing. I thought the Osprey Exposure 50 might be a wise pick for my new alpine / climbing / travel pack, even though (at the time) there were no internet product reviews. I didn’t think the lack of reviews would matter, seeing how Osprey has a great reputation, the pack’s feature-to-weight ratio, and the categorization as a climbing pack. This pack treated me well for a climbing trip to Indian Creek, UT (this Osprey 50L pack handled the biggest rack of gear a trad-climber will most likely ever require) plus a trip to Costa Rica. HOWEVER, after only a few months, I experienced three different flaws (top pull-string blew out; beginning of a major hole in the bottom stitching, and tears/punctures in the bottom). I returned this pack, seeing how my previous pack (Gregory Reality) put up with years (not months) of weekly abuse. In Osprey’s defense, I am considering buying it again, based on the feature-to-weight ratio and Osprey’s overall reputation. We shall see.
