The Old Man Mountain Ponderosa bikepacking panniers 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. Secured them to the rack with camming velcro straps at the top and use the lower compression strap to loop through the rack and guarantee that your bags don’t turn into dumbo ears when you hit a bump, no matter how rough. All of the compression straps replaceable so next time you spill some salsa on your bag and Mr. Mouse nibbles through one you can just swap it out, nice and easy.
