The Starlite ultralight pack is the only frameless pack that has been both scientifically and independently tested to comfortably carry up to 35 pounds (see Backpackinglight.com's Frameless Pack Review Summary).
Designed for the long distance ultralight hiker, the Starlite has many features that make it feel right at home on your gear list. Whether you're a long distance hiker or weekender looking to lighten your load, the Starlite is the right pack.
The unique suspension system of this incredibly light 23 ounce frameless pack, allows you to comfortably carry loads up to 35 pounds. Should you wish to carry additional weight or prefer the added rigidity of an internal frame, simply slip in the two (optional) 24" stays to create an internal frame pack.
Used 13 days, in excellent condition with stays. New $160, will sell for $125 shipped to lower 48. E-mail me at idahomtman at backpacker dot com.
