Hemlock 5L with FLiP Cages by Old Man Mountain
These quick detach fork packs (or any 3-pack mount) are ready for everything! Sunshine or rain, your gear will stay dry and protected in these 100% waterproof, TPU fabric panniers with welded seams and Hypalon reinforcements.
Hemlock bags attach to your bike with a simple hook and then FLiP of the lever for an ultra secure and rattle free ride that can be removed in a second! FLiP Cages are the only quick detach mount that is also a cargo cage for optimal flexibility to carry what you need.

Quick Mount and Reliable!
We’ve spent years developing a reliable and robust quick detach mount that can withstand riding in the toughest conditions. FLiP is easy to use in the cold, in the mud, with gloves, in the sandy desert.

What Makes the Hemlock 5L so Special?
100% Waterproof
Made from TPU fabric with Hypalon reinforcements, fully welded seams, and a roll top enclosure. You can be fully confident that your gear will remain dry and protected, even if you don’t quite make that stream crossing.
Quick Mount
No more struggling with straps and crushing your stuff. Simply hook the bottom of the bag and rotate the handle 90 degrees to lock the Hemlock bag in place, securely and silently!
All Terrain Ready
FLiP Cages and Hemlock bags are built for whatever riding you want to take on. Whether rowdy shredpacking or traversing around the world, they are ready for anything.
5 Liter Capacity
5L is perfect for a sleeping bag, sleeping pad, or cook kit with a little space to spare. The 5L capacity is measured while still rolling the closure three times.

FLiP Cages are the first quick detach mounts that are also cargo cages with optional cargo feet. Need to carry a more water on your trip? No need to swap mounts, just strap the Nalgene on and go!
