Problem: When loaded to the hilt, roller bags become tippy and hard to wrangle through airport mazes and over curbs and rough terrain.

The thick, rubbery TPU (thermoplastic urethane) fabric holds its shape and rebuffs abrasion as well as rain, and the large D-shaped opening means that you can peel back the protective padded top for easy gear access and organizing.
