Our backpacks both come with a full frame made from carbon fiber arrows and a zlite sit pad the slides into the back panel for comfort while walking. We currently offer one model of backpack in two different capacities, 35 liter and 45 liter. The weight capacity of our backpacks is about 35 lbs. This can be exceeded for a few stretches if desired, but the pack will wear more quickly and feel ... like you have 35+ lbs on your back.
"This is the best fitting and functioning pack I've had in many, many years on trail. I hope that it holds up for a long time, but at this point I would likely replace it with the exact same thing."
"I got the 50 liter bag and love it. It's super light, but super durable. Using arrows as the support structure is genius. It feels great with my 13.5 pound base weight, but I just wanted to see what it felt like at 40 pounds with a ton of water and the arrows really help spread the weight between my shoulders and hips. The shoulder straps are legit and very customize-able with the webbing they sew on the top so you can clip anything you want into it. Using the small sit pad as the back support is comfortable and really useful once I take a break to sit on."
