With a 40-year experience in producing innovative outdoor gear, Colorado-based Mountainsmith knows a thing or two about crafting trail-ready bags. Their Scream Series Ultralight Backpacks are ready for whatever the elements can throw your way. Best of all, they weigh close to nothing.

Available in different sizes, the backpacks are constructed of a high tenacity fabric with a special coating and Aramid yarn woven throughout, preventing extended tears and abrasion. The new 55L model weighs in at 2lbs 13 oz, has a more supportive waist belt and backpanel, load lifters for efficient carry, dual front storage pockets, extended roll-top closure for varying load sizes, and deeper side mesh pockets.

The Scream 25 stuffs into its own top lid pocket for convenient storing, while the all-new Scream 20 weighs a mere 14 oz and converts to a compression sack, making it ideal for ultralight peak bagging or minimalist day hikes.
