Anyone ever use lightweight climbing packs for backpacking? I'm thinking about the Patagonia Ascentionist 45, and was wondering what people's thoughts would be on a pack like this.

I have used my climbing packs for backpacking. I actually did a week's trip with a 2400 cubic inch climbing day pack. If you can fit the gear inside, then OK. Climbing packs are heavier for the same capacity because they are made to withstand scraping on rocks. I would not buy a climbing pack for backpacking, but if you already own it, use it.

Thanks. The Patagonia Ascentionist 45 is 2 lbs 3 oz , which is pretty darn light. Just not sure how comfortable a pack like that would be on a multi day trip.

Key are whether the back length is good for you because it's probably not adjustable, and then how good is the load support/control? Also, will you miss side pockets?

Simple, rugged packs with few snagging points are a plus for heavy brushwhacking or squeezing past rock. They can also be good at keeping water out, depending on the number and location of seams.

I like it. You won't need extra water proofing, no garbage bags etc, so the effective weight is less, and there is a lot to be said for the durability. If it is comfortable to you, thats a pack that can be thrown around and always be ready for more.

check out the Arc'teryx alpha f L 30 backpack. it weighs 20 ounces and runs about $200. it looks fairly waterproof. I am thinking about buying one for my wife.
