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.
