Outdoor Research Women's Banff Bodysuit

rated 5 of 5 stars I purchased this for my wife a few years ago. She absolutely loves it. It adds great warmth and wicking without significant bulk -- No overlapping or bunching fabric at the waist.

Outdoor Research Saturn Suit

rated 5 of 5 stars This is a great cold weather suit. I deer hunt a lot and I will not leave home without this layered suit. Lightweight and breathable. It holds body heat and keep me warm. The other benefit is with this suit I don't have to wear much clothing which allows me to maneuver around better while bow hunting...great product for cold weather activity. Full review
