Well, I finally took the plunge. I have been a faithful Mariposa user for I don't know how long, and will remain so for certain hikes. That said, I have a base pack weight that easily works with this pack.
The Mariposa looks so deflated on weekend trips. It's nice in a way because I don't have to really compress my sleeping bag, etc. I really felt it was time I "graduated" to a new bag of tricks.
Anyway, I took the big leap and dropped $60 on the Whisper Uberlight Pack (sans waist belt). I know for a lot of you this isn't much of a leap but it's a big thing for me. The weight savings vs the Mariposa were significant. I'll probably try it out this next weekend and see how it sits with me.
Depending on how well it works I may be able to push this further than a weekend. My base weight (+ pack) will be 5.12 lbs with this pack and the web site says up to 15 lbs. So assuming I can fit everything in the pack I am thinking I can fit more than a weekends worth of food in there. We'll see. I am not sure about 15 lbs but 8-10?
I am sure others use this backpack. I would love to hear of the experiences other have with it and how they get the most out of it.
