The standard design of crampon bags for decades with this rectangular pouch with integrated tie-strap. Often crafted from waxed canvas, and eventually changing to a duck canvas, they would feature different materials inside such as leather to protect from the sharp points of the crampons.
Snow Peak made subtle changes to these bags over the years, with shifts to primary and secondary colors, tie straps and woven labels. But the overall function and form would remain the same until crampons were discontinued by Snow Peak in the 00s.
We suggest either the Multi Container S or Kitchen Mesh Case S as a modern replacement.
