RadLite 1KG External Frame 66 liter StackPack
with the exclusive Hook Belt.

Total weight is one kilogram [35 ounces]. Need even more room?... stack four Barrel Bags for up to 100 liters. The StackPack Barrel Bags eliminate the biggest hassle in backpacking... finding that thing you need fast! The full width Velcro closures put you just inches away from any piece of gear. Nothing gets buried 2 feet down at the bottom of your pack.

The Hook Belt allows you to lift the pack frame off in a few seconds and set it down with no belt dragging in the dirt/mud/thorns. The StackPack sits upright and clean all by itself on the frame shelf, no need to lean it against a tree. The Hook Belt can remain around your waist for the entire day... perfectly adjusted.

With the external frame you do not need a sternum strap because you can slide the shoulder straps horizontally along the top tube for an optimum fit. In the winter, the StackPack is the only pack system that allows your down jacket to be fully lofted over your back.

The modular design means you can build a PCT thru-hike pack or an urban travel pack that exactly fits your needs. And, if you lose or break some piece.... strap, frame tube, barrel bag,... that part can be replaced fast, in the field, at a low cost. Want to design your own pack?... you can buy just the Frame with Shoulder Straps and Hook Belt and mount any other bag/bags on the frame.

There is a big pocket at both ends of each Barrel Bag. Reach back and grab the mosquito spray fast. All your gear is easy to find inside the individual rain-proof Barrel Bags with full-width velcro openings. You can have anything you need in your hand 5 seconds after stopping. On the trail since 2005, the StackPack works for overnight trips, border-to-border thru-hikes, and any trek in-between.

Set the shoulder straps kinda loose and there is no weight compressing your spine. If you tighten the shoulder straps you can share the load between shoulders and hips. The coolest and warmest pack design.... in the summer no hot sweaty pads press on your back. The pack pumps air as it moves back and forth a little with each step. In the winter, you put the Hook Belt on, then your jacket. Your jacket's inssulation stays fully lofted. You lift the tail of the jacket to drop the frame onto the Hook.

The 7075-T9 aluminum frame is hand made in our shop in Texas. The joints do not fail from fatigue stress like welded frames. The bottom shelf will hold a bear canister, chainsaw, baby seat, etc. The Barrel Bags are sewn in our shop in Texas from yacht racing sail fabric made in the USA. Free Shipping, Lifetime Warranty, and 30 Day Free Trial.
