This depends on the season you are in.
Winter: You’ll want to dress for playing in the snow all day. We suggest a good pair of polypropylene style long underwear (top, bottom–and women will appreciate a good sports bra); a good pair of ski socks (polypropylene or wool, no cotton); comfortable middle layers over long underwear suits such as sweaters, sweatshirts, and sweatpants; polar fleece; waterproof and windproof outer layers (ski or snow pants and jacket); gloves. Helmets are required (and provided free of charge for all riders).
Summer: You’ll want to dress in long pants and a comfortable shirt. You should bring along with you a rain suit, extra socks and closed toe shoes. Bear spray (available for rent or purchase) is always a good idea.
Spring/Fall: Montana’s weather changes fast. Always be prepared for cold with rain or snow as a possibility. Bear spray (available for rent or purchase) is always a good idea.
A few additional suggestions: Earrings can be uncomfortable under helmets, so you will want to keep that in mind. Sunglasses or goggles (available for rent or purchase) are a must. A camera (available for rent) is also a must-have to capture the spectacular beauty of Montana’s high country. Always remember to bring fluids and food.
