Brandi is going to be at very high altitude in Utah where afternoon thunderstorms could be a daily occurrence. She's going to be mountain biking where shelter is not available except for the huts at night.

You'll probably need rain gear more for outbursts than steady non-stop stuff, but it could happen.

I've never taken waterproof gloves but I do be sure to have long fingered-warm gloves. Surgical gloves would be easy to carry in your seat bag and just use for a short while.

A waterproof breathable jacket is probably more important than rain pants. You do have tights?
