REI UL 60 Pack

Really impressed with this product. This is my first ultralight pack and I can't imagine why I'd ever go back. Just used it for three days in southwest CO in fairly poor summer conditions and was totally impressed. The thin ripstop fabric (so thin it's actually transparent) made me worry at first, but I stuffed it hard and it laughed at my attempts to abuse it.

I do however still question how it will stand up to long term use. REI recommends 40 or 45 lbs. max but that's not too difficult to stay under with the lightweight products available these days.
