Hemlock Bags 5L w/FLIP Cages

Old Man Mountain Hemlock Bags 5L w/FLIP Cages are quick-detach, waterproof fork packs designed for riders who want stable, low-fuss storage on any 3-pack mount for bikepacking, touring, and rough-road riding.

Built from welded TPU fabric with reinforced high-wear zones, the Hemlock bag is made to keep critical gear dry while resisting abrasion from trails, grit, and repeated loading. The hook-and-lever attachment system locks the bag to the included FLIP Cages for a secure, rattle-free ride, then releases in seconds for fast off-bike access at camp or resupply stops. A simple roll-top closure seals the load without relying on zippers, and the clean, minimal branding keeps the setup low-profile on the bike.
