Scream 50L WSD Backpack



For you lightweight backpackers out there, the Scream just made your life a whole lot easier.

The Scream 50 WSD weighs only 2 pounds 10 ounce - perfect for lightweight backpacking. With a myriad of features, it's surprising the Scream doesn’t weigh more.

Roll-Top Closure - easily compress and compact your load down to minimize shifting. The large opening makes it easy to pack and unpack your gear while the Hypalon seal keeps your gear safe inside. Plus, with no zippers to snag, it's built to last season after season. Over/underside compression straps easily pack your gear down in two different ways.

Front Panel J Zipper - easily access the interior of your pack to grab your sleeping pad, bear canister and quilt to set up camp.

FreeFlow Ridged EVA Back Panel Padding - built to keep you comfortable, the EVA padding provides a comfortable barrier between your back and gear.

Multiple Clip-In Points - with multiple exterior lash points easily secure gear to the outside of your pack.

Removable EVA Framesheet - for lightweight travel or packing down, the EVA Framesheet easily removes along with a ½” aluminum stay.

Load lifter Adjustment - fixed shoulder straps with load lifter adjustment enable you to get the perfect fit.

High-Density Foam Waistbelt with Dual Zippered Pockets - built to keep you comfortable, the foam wraps around your waist while the large pockets stash your snacks, water and other hiking essentials.

Forward Pull Waistbelt - keeping the weight off of your shoulders and back and onto your waist, the waistbelt features adjustment webbing to achieve the perfect fit.

Dual-Density EVA/PU Shoulder Straps - built to keep you comfortable, the shoulder straps minimize the weight on your shoulders while cushioning them with soft foam.

Internal Hydration Sleeve - fitting up to 3 liters, the hydration sleeve easily fulfills your water needs. An elastic sternum strap and bite valve catch keep the straw easily accessible.

Dual Side Panel Mesh Pockets - for easy access on the trail store your water bottles (up to 32 oz) on each side of the pack.
