Airblaster Men's Ninja Suit

rated 4.5 of 5 stars Looking for a "onesie?" The Airblaster Ninja One-Piece Suit offers all I need for a full coverage, draft free, mid-weight base layer...without the bulk! As is often the case for me (being on a fixed income) I enter review contests to win gear that I need (but can't afford) for my passionate pursuits. Winning another site's campground review contest, I garnered a coveted gift certificate to Airblaster ( I must admit, the gift certificate was substantial and I was no less grateful...but… Full review

Patagonia Ice Nine Suit

rated 5 of 5 stars The best winter mountaineering shell I have ever seen. Bright colors for visibility in low visibility situations or avalanches. Heavy duty Gore-Tex material prevents punctures from ice axes, crampons, rocks from hit when doing a sitting glacade. Many many zippered vents full length removing the need to take your plastic boots off in order to put on the one piece shell. Best piece of kit I have ever purchased. I have put mine through an enormous amount of abuse and falls and the suite is still intact… Full review

The North Face Himalayan Suit

rated 5 of 5 stars This is the best down suit you can buy for your money. It's warm and does its job in the coldest of weather. Keeps you warm and dry, very comfortable, it's like wearing a nice down sleeping bag. It's great for any winter activity. It's best for winter camping and long treks or walks on cold days. I wear the suit all the time around the house or outside, it's that comfortable. I have gotten many compliments on the suit. I would recomend this suit to anyone whos is always cold or wants to be comfortable… Full review

Stoic Women's Merino 200 1-Z Suit

rated 5 of 5 stars Bought this for my wife for Christmas. Fit is excellent. Not too tight. Initially seemed a little long, but she is 5'1" and the XS fit fine. Prob would work if you were a few inches taller as well. Material and seams are nice. Back paneling for bathroom use are convenient. Would be nice if this were a feature of the men's product as well.

REI Windy Peak Snowsuit

rated 4.5 of 5 stars We love it, it still fits our petite 2 year old with the growth tucks. It's a slim fit which we like, not bulky. Warm and cute for our winters here,  a -5C average. The zip pockets are unnecessary at this age. Full review

The North Face Halo Detachable Suit

rated 4.5 of 5 stars This suit is a great one-piece. It keeps me very warm and when I do overheat a little it breathes very well. I really wish they would have made a XXL as being 6'2" 250 is maxing out the XL. I have taken this thing in deep powder and through the trees at Sierra many times and i always stay dry. The only fault of this suit is the pants are not functional when separate and the jacket is a little short, in essence this can be used as a one piece. If you're looking for a suit that keeps you dry and warm… Full review

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. Once you try a one-piece suit like this, you'll never go back. She won't go skiing without it. Full review

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

Avalanche Wear Fleece Bunting

rated 5 of 5 stars Great base layer for taking your toddler out for a mid winter ski. What I like the best is that you can fold over the sleeve pockets and keep your child's hands inside. You don't have to worry about him or her pulling off the gloves. Also, the built-in hood allows you to keep the neck and head warm, a major heat loss area. Full review
