The Spry 4.0 is  a minimalist pack that can be utilized in a variety of settings. The improvements on the award winning Spry series improve functionality, comfort, and durability. For capacity, the front harness pockets have been updated to accommodate a variety of hydration or gear comfortably and securely. The back panel has a sweat-proof liner under polyester mesh to keep the contents in the main compartment dry but still breathable during longer adventures. A sweat-proof zippered pocket alongside the main compartment allows for storage of items you want secure and dry. The main compartment is a 4-way stretch mesh designed to expand or compress to the load and is built to carry a 1 liter reservoir. The magnetic closure on the main compartment keeps the contents secure and provides quick accessibility. The back panel also features a shock cord to carry additional clothing if needed. The UltrAcool Light Mesh on the shoulder and harness of the Spry 4.0 make the pack very durable and incredibly lightweight. One size fits most.
