While the Mini Tool Kit is the smallest bag in the Jandd line, it is still made to the same strict specifications as Jandd's largest mountaineering pack, which is over 250 times as large. The Mini Tool Kit is just big enough to fit a patch kit, tube, and tire irons. For extreme durability, the main panel of the Mini Tool Kit is doubled with an extra layer of nylon to prevent premature wear at the seat post. In addition, all seams are fully taped to prevent fraying, and the 3-point hook-and-loop suspension is triple-stitched for durability. As on all Jandd products, stealth zipper heads are standard.
