The Jammer Bag

Regular price $135

It's Jammer time! A unique high volume, rackless, universal handlebar/saddle bag. This bag is perfect for city commuting/road touring/dirt bike packing or casual beach rides  - load it up with the essentials and have plenty of room for more gear. This bag was designed for cyclists by cyclists! It is easy use, fun to ride with and a treat when you need it; forget your bike is loaded down with the help of the Jammer! Lightweight, durable and water resistant!

There are two external expanding front pockets with a flap lid. The lid has a 2" strip of 3M reflective and a blinky light loop directly above. This bag was made for either front or rear use and will accommodate a variety of bikes, handle bars and different riding styles. The closure straps (C.W.S.) were designed to give adjustable positions for the optimal weight to tension ratio. You can load this pup up and really cinch it down to create a stiff and compact bag with zero sway or sag when mounted appropriately. The bag has an internal structure to give form and an internal stiffener which will not bend or break. 

When fully expanded the Jammer will reach up to 9.75L in volume and can be rolled down to more than half of that. 

When using this bag on the rear, note that the bag mounts to the Saddle Loops. If your existing saddle does not have the Saddle Loops then please refer to our recent blog post.

PRODUCTION NOTE: This bag is currently on back order and will not be available until at the earliest the first week of May. We are accepting orders for this bag but that will only put you in line for the first production run! Thank you for understanding :) If you have any questions do not hesitate to ask!   

Installation Guide Ft. Rat as Rat!


Our material selection is ever expanding and made to fit the look of your bike! The outer shell is made of either 600D Poly, 1000D Cordura, X-Pac or Waxed Canvas with a high denier rip stop nylon liner.

The Jammer Bag uses a roll top closure combined with dual vertical adjusting straps. We call this our C.W.S.:

  • Closure
  • Webbing
  • System

The C.W.S. creates a 4 point compression (as shown in the photos above) and works to keep the bag cinched tight as well as giving it the 4th mounting point (either around the handle bars or saddle rails) which then eliminates sway and sag. Simply remove the webbing strap from the d-rings and restring the webbing around the point of interest then back to the bottom d-ring and up to the roll top closure buckle.
