It features a waterproof main compartment with internal sealed seams and a roll-top closure with an integrated zipper for quick access or added security. The backpack is compressible for travel and includes a mesh compression sack. It has UHMWPE reinforced wear parts for extreme durability, abrasion resistance, and tear resistance. The Freerain is compatible with hydration systems and includes a fixed hip belt with pockets. It also has an adjustable chest strap, two gear loops with corresponding Hypalon-reinforced shockcord attachments, and breathable, weight-distributing shoulder straps. Additionally, there is a waterproof zipped front pocket with a sealing zipper and oversized mesh side pockets. Compression straps with side buckles help stabilize loads or attach external gear, and a load lifter allows for adjusting weight distribution and fit.
