The short version
Wear what you'd wear on a cold day — base layers, regular pants, a sweater or fleece. The operator's snowsuit goes on top. Avoid cotton anywhere near your skin. Cover your face and you'll be comfortable for the full ride.
What the operator provides
- Insulated full-body snowsuit (bib or coverall style)
- DOT-rated helmet
- Snow boots (sizing available at check-in)
- Insulated gloves or mittens
Total weight added is significant — the suit alone is bulky. You'll need to move freely in your base layers underneath, not be bound up in ski layers that don't fit beneath the snowsuit.
What to wear underneath
Base layer (next to skin)
- Long underwear top and bottom — synthetic (polyester) or merino wool
- Not cotton. Cotton holds sweat and chills you. The single most common cold-weather mistake.
- Snug fit, not loose
Mid layer
- Regular pants — jeans are fine if you have synthetic long underwear under them
- Long-sleeve shirt or thin sweater
- Light fleece or wool sweater optional on the coldest days
Avoid bulky ski layers — they fight the snowsuit. The suit itself is the warm layer.
Socks
- One pair of wool or synthetic socks, knee-high preferred
- Not two pairs. Doubled socks cut circulation and make your feet colder, not warmer.
- Not cotton (same reason as base layers)
Face coverage — the thing most first-timers forget
The single most underrated piece of gear. Helmet vents let cold air onto your face at speed. After 30 minutes of cold wind, your cheeks and nose burn. Bring one of:
- Balaclava (best — covers everything below the goggles)
- Neck gaiter or buff (good — pull up over nose)
- Bandana (workable — folded triangular and tied)
Eye protection
The operator's helmets have visors but the visors fog at temperature transitions and don't seal against wind. Bring:
- Goggles (best — ski/snowboard goggles work)
- Sunglasses (acceptable — wraparound style is better than thin frames)
- Both options should be at least lightly sun-tinted; the Sierra sun off snow is intense
What NOT to wear
- Cotton anywhere near skin. Long underwear, socks, undershirts — all should be synthetic or wool.
- Heavy ski jackets. Wear them to the staging area, leave them in the car — the operator's snowsuit replaces them.
- Multiple pairs of socks. One pair, good ones.
- Loose scarves. Anything that could catch on the sled is a hazard. Use a balaclava or buff instead.
- Contact lenses without goggle protection. Wind dries contacts out fast.
Optional but smart
- Hand and toe warmers (Hot Hands, etc.) — fit inside gloves and boots, $1–2 each, worth it on the coldest days
- Lip balm with SPF — the wind plus altitude destroys lips faster than you'd think
- Sunscreen for the face — applied before suiting up
- Backpack lock-box (a small dry bag) for your phone, wallet, and keys — the staging area has lockers but you may want gear with you
- A change of socks in your car for the drive home
For kids and smaller adults
Operator gear runs in adult sizes — typically men's S through XXL. For smaller adults and older kids, the snowsuits and helmets may be loose. Bring extra layers to fill the gap inside the suit, and tighten boot laces aggressively. Verify the operator's age and size minimums before booking — small children may not have gear that fits.
