KemBag is a lightweight NO STRAP design backpack to hold ice or ice packs against your back while you ride. It is designed to clip on your back jersey. Inserted between your back and your jersey. The ice provides direct cooling to your core, helping you stay comfortable and perform longer in hot weather. It comes with a zip bag that can be used to keep the ice from dripping. You can also leave the zip bag half an inch open if you want ice water dripping.

Typically 45–90 minutes depending on outdoor temperature, ice size, ice pack size, and how hard you're riding. Always use the clear zip bag with NO holes to keep the cooling longer.

No — slide down your jersey zipper to chest level. It clips on and off quickly at the back of your jersey. Then slide your zipper up to secure the backpack in place. You can reload ice at a rest stop or café without any hassle.

The backpack sits between your jersey and your back. It is designed not to shift or bounce while riding. Most riders forget they're wearing it within a few minutes. We do not recommend wearing loose jersey.

Hand wash or machine wash with cold water and mild soap. Air dry. Do not tumble dry.
