Jack's Sacks' Frame Sacks are equipped with sturdy YKK Uretek zippers for lasting quality and effortless functionality

The waterproofing layer of most fabrics is located on the inside of the bag, which can lead to damage if not protected. To prevent this, all Frame Sacks are lined with durable pack cloth in a bright color for improved visibility.

The frame contact panel (aka the gusset) is padded to protect your frame.

A shallow map pocket on the non-drive side is included with all Frame Sacks for organization.

*please note the tiny frame sack only has one compartment

All full frame sacks come with two drive side compartments for tidy storage. Fold up the Velcro shelf to transform it into one big nacho in a pinch. This shelf also stops the bag from bulging when jam-packed!

Lower compartment can be made to fit Apidura water bladders

Optional L zip lower compartment for the ultimate access!

Get what you want at no extra charge!

Laces are my preferred option. The shock cord provides even support to the bag, keeping it smooth and the zippers straight, even when overpacked.

Straps offer a practical solution for easy and efficient bag attachment. Ideal for users on long trips and switching between bikes

Certain applications enable the bag to be bolted in, designating it as a semi-permanent installation, creating a dialed look

Hydration/cable ports are a standard feature on all Frame Sacks, eliminating the need to keep your zipper partially open while charging your GPS, powering a headlight or staying hydrated

*please note Tiny Frame Sacks are typically too tiny for a port.
