so i got this frameless pack given to me. just wondering if any of you have traveled with a pack with no frame. i kinda like the idea because its small. fits my sleeping bag, jacket and has all the little extra pockets all inside. plus its waterproof. Anyways i want to travel light this summer and figure that keeping it small will help me not carry around a bunch of useless shit. So yeah just wondering if even just having roughly around 20 lbs is going to give me a bunch of issues traveling as far as my back and shoulders n such. maybe one of you have tried this route?
