The reviewer found the floppy bag can collapse inward during packing, particularly when the brain pocket contains items, slowing hurried packing. The Tom Bihn Shadow Guide 33L is described as a minimalist backpack and the first Design Lab release, exploring new materials. The reviewer reports a black Ballistic Nylon construction using different nylon weights across the exterior, bottom, and interior.
The simple structure makes the pack easy to load with groceries or a substantial amount of shopping when errands require extra carrying capacity. The reviewer highlights O-rings for attaching pouches and an external laptop panel that provides quick access for daily laptop carriers.
