I’ll caveat here and say that I dont have extensive experience with this pack. Ive looked it over, packed it up, and borrowed a friends for some trial-and-error, but nothing seriously substantial.
That being said…
If you feel comfortable fitting a load for an “extended trip” into 2000ci, then this would be a good pack for it.
Its compression is excellent. It will sqish up into nothing. It has the same compression as other UL GG packs, but it also has the top flap compression straps and the beavertail.
GG claims its comfortable up to 25lbs… Id say thats accurate over short distance hikes, but less is better. 20 is where Id limit the weight if I knew I’d be walking for any appreciable distance… and Id try to keep it closer to 15 than 20. I dont have one in front of me, so I cant tell you if using a sleep pad could be used to add rigidity to it, but I think it might be too short for a standard pad.
I like the design enough Ive written to GG asking them to make one just slightly larger… a Wisp/Virga hybrid basically.
