GoLite Pinnacle or Gossamer Gear Mariposa
I'm trying to get rid of my two old packs (GoLite Jam1 and a 6 pound beast) and combine their functionality in one. I'm looking for something that will handle 30 pounds comfortably, either for overnight winter outings or for a little longer lightweight backpacking trips. Because of cost, I've narrowed it down to two options: GoLite Pinnacle or Gossamer Gear Mariposa.
The pluses for the Pinnacle are, first of all, my Jam was very comfortable (except for the shoulder straps) so I have experience with their design. It also says it can carry 40 pounds. Seems optimistic for a frameless pack, but it makes me think it could carry 30 comfortably (I know a lot goes into HOW I pack it, using a sleeping pad as a cylindrical frame, etc.). I like the padded shoulder straps and hip belt and I found the frameless pack to be more comfortable than other packs as it hugged my back very well. I like the larger pocket with the waterproof zipper and the compacktor system for UL trips. I also like the loops to hold my trekking poles when not in use. This pack is also very durable, with the Dyneema fabric.
For the Mariposa: it is lighter, it has (removable) carbon frame stays plus a pocket for a pad, and it's about the same capacity (a little less). It says it handles 30 pounds comfortably. Also, I'm about 6'5" tall. I have difficulty consistently measuring my torso, but I think it's somewhere around 21-23 inches. The Pinnacle says it only fits up to 21.5 inches, but it seems like that's less of an issue on a pack without load lifters or a frame. The Mariposa is supposedly designed to handle up to a 23 inch torso. Also, it has a nice Y-strap and an integrated whistle. I like to use a 3/4 length Insulmat Max Thermo pad, but with the GoLite I'd have to carry an ADDITIONAL 3/4 length (maybe a little smaller) closed cell pad to use as a "frame." With the Mariposa I can carry the NightLight to use as a frame, sit pad, and under my feet at night.
Any thoughts? Experiences? Suggestions?
