Custom Size Pack Liner Dry Bag:
Our liners are flat like an envelope. To measure for a custom sized liner, lay your backpack flat on the floor, completely empty.

Measure the maximum width of the body of the pack from one side to the other.

Measure the maximum height of the pack from the bottom center to the top, with the pack open.

In the attached pictures of a Blast 36, the dimensions are 19.5" wide by 38" tall which is our standard size liner above. As long as your pack is smaller than that the standard liner will completely fill the pack.

Enter the dimensions (width x height) in the box below. Or email us the details.

Custom sized liners are non-returnable unless there is a defect in the construction.
