The X4 is the 3-day pack of the future: simple, robust, highly organized, lightweight, and comfortable.
The X4 is a variation of our popular X1A1 model, without a scabbard (see the very similarly designed X3 pack if you prefer an incorporated Backscabbard). The X4 has a unique contour shape that tapers at both the top and the bottom, giving the pack an excellent close-to-the-body ride. It is fully compressible with pairs of side-mounted compression straps that draw the load upward to optimally position the pack's contents over the wearer's center-of-gravity.
Well endowed with PALS/MOLLE compatible webbing, the pack is easy to accessorize, with ample space on the interior and exterior panels for attaching an array of accessory pouches.
An optional accessory, our innovative Endo pack frame is compatible with this pack. The Endo slides into the pack's main load bay, adding both vertical and lateral structure without compromising comfort or the pack's quiet ride.
