  • Goggles
footwear
Footwear
  • Mouse boots
  • Sorels or Kamiks
  • Leather mountaineering boots

Sneakers and Gore-Tex hiking boots don’t cut it.

$$$$$
  • Clothing is not something MITOC rents, so you’ll have to get it on your own.
  • Get items that fit and will last. They can be found cheaply, if you look.
  • Check out the MITOC Links page for info on web sites and local stores.
