RadLite1KG - 66 liter External Frame StackPack
with the exclusive Hook Belt.

On the trail since 2005, the StackPack works for overnight trips, national park treks, border-to-border thru-hikes, and any adventure in-between. The Barrel Bags eliminate the biggest hassle in backpacking... finding that thing you need fast! The full width Velcro closures put you just inches and seconds away from any piece of gear. Nothing gets buried two feet down at the bottom of your pack. And our new 2017 design puts a big mesh pocket at each end of the Barrel Bags. Reach back and grab that bear spray fast; or stuff your gloves in, or stow your GPS. For little trips you can use just two or only one Barrel Bag. Need even more room?... stack four Barrel Bags for up to 100 liters. Or add the new Wilderness Wheels to make an ultralight wilderness trailer.

Ultralight with a total weight of 1 kilogram [35oz]. (The NorthFace Terra50 and the Osprey Atmos weigh 4lbs, and the Kelty Yukon weighs 5lbs.) We achieve this level of performance by using artisan construction processes in our Texas shop. USA sourced 7075-T9 aluminum tubing and racing sail fabric are purchased in small quantities and quality tested before production. Calibrated milling machines are operated by hand, three different sewing machines are setup and tuned for different fabric components. We make batches of four at a time to insure the best quality and to speed up incorporating new features and improvements.

The Hook Belt allows you to lift the pack 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 alone on the frame's bottom shelf, no need to lean it against a tree or prop up with a hiking pole. The Hook Belt can remain around your waist for the entire day... perfectly adjusted. The only pack design you can configure to put no pressure on your shoulders or spine. All the weight can be directed straight to the hip belt and lumbar pad. With the telescoping frame you don't need a sternum strap because you can move the shoulder straps top attachment point horizontally and vertically for an optimum fit.

The modular construction means you can configure a PCT thru-hike pack or an urban travel pack that exactly matches your mission. 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. The bottom shelf will hold a bear canister, chainsaw, baby seat, etc. See the pictures below for examples.

If you adjust the shoulder straps a little loose there is no weight compressing your spine. If you lower the frame slider and tighten the shoulder straps you can share the load between shoulders and hips. The external frame enables hiking with the coolest and warmest pack design.... in the summer no hot sweaty pads press on your back. The pack pumps cooling air as it moves fore and aft a little with each step. In the winter, you put the Hook Belt on first, then your parka. Your jacket's insulation stays fully lofted. You just lift the jacket tail before dropping the frame onto the Hook. Free Shipping, Lifetime Warranty, and 30 Day Free Trial.

Converts your StackPack into an ultralight Hiking Trailer that will roll over 90% of wilderness trails. WildWheels slide up into the bottom of the StackPack Frame and are held to the frame with the Shoulder Strap clips. No bolts, or screws, or hinges. It takes only 10 seconds to attach or detach. If you have a pack that weighs 40lbs the wheels will carry about 30lbs leaving only 10lbs on the Hook Belt. Very stable with a 19" width that rolls down narrow trails. Delivers a smooth ride over rocks, gullies, roots, gravel, smoothly rolls up or down building stairways. If the trail gets too knarly or too vertical just lift the StackPack and set it onto the Hook Belt with the WildWheels hanging down. Walk until the next rolling section, then lift off the pack, extend the shoulder straps to full length, drop the top bar into the Hook and roll on down the trail.

The wheels have sealed ball bearings so you can roll through mud, under water, and along a sandy beach with no problems. The solid tires (no flats) will last thousands of miles. And the wheels are easy to replace... held on with a nylock stainless steel nut. Constructed of anodized aluminum tubing with epoxy bonded joints. Never rusts or corrodes. You can strap heavy gear like ammo boxes to the WildWheels frame... or give the kid a ride! Weight is 2lbs. The StackPack with WildWheels weighs less than almost all other external or internal frame backpacks.
