The new rendition of the classic Glacier features all the Expedition Series updates. From fit and sizing to fabric and frame, it offers superior Load Carriage™ and comfort for your long weekend outing as well as more extended backcountry trips. It’s a top-loading pack with a dual draw cord shroud to increase weather resistance and allow for upward expansion. Mystery Ranch's Speedzip™ sleeping bag compartment will accommodate even the warmest, bulkiest bag. The lid has two compartments for Type-A organization and is easily converted to a summit pack by transferring the main packs’ harnessing over to the lid.
