Product Details

The way that the fabric is woven keeps the fabric from ripping further when you encounter and unfortunate puncture. This quality fabric brings peace of mind that you know it can be easily repaired and will not fail you on the trail. Combine that with an abrasion-resistant 610d CORDURA® layer on the bottom, and you have an unbelievably durable pack at an unthinkably low weight. To lighten your load a bit more, the frame sheet on the back panel is removable to leave at home or use as an ultralight sleeping pad. The roll-top closure is convenient for carrying larger and smaller loads between your food drops. Additional features include dual front storage pockets(sized to fit the Mountainsmith Mountain Shelter LT), smart phone compatible waist belt, internal hydration sleeve, deep side mesh pockets, easy forward pull waist belt, and pocket pass through compression straps. To bring you peace of mind for your backcountry investment, Mountainsmith offers a lifetime warranty on their products. If counting ounces for minimizing weight is your backpacking style, then the Scream 55 is for you.
