King of the mountain.

When plummeting temperatures chase the crowds indoors, pull on the Norrona Men's Wool One-Piece Long Underwear and take advantage of having the mountain all to yourself. Made from merino wool and a touch of nylon, this baselayer offers the perfect combination of comfort, durability, and moisture-wicking power. Made for a variety of alpine activities, this one-piece suit will keep you warm at different activity levels. Zippers on the outer thigh let you dump heat fast when things start to heat up. A fitted hood provides extra protection from clawing cold. Wool's natural resistance to microbial growth reduces smell, so you'll be able to take it on your 3-day hut trip and not hate yourself by the end.

Great for Hunting.

  • Familiarity: I've used it once or twice and have initial impressions
  • Fit: Runs small
  • Height: 5'8"
  • Weight: 174lbs

I bought this to use for hunting and it works great! It doesn't bunch up or bind and it kept me good and warm.

Athletic Fit one piece

  • Familiarity: I've put it through the wringer
  • Fit: True to size
  • Size Bought: large
  • Height: 6'1"
  • Weight: 167lbs

I've worn this 4 days in a row through a storm cycle and with no odor issues. Its warm, comfortable, and very well designed. I will point out that it is an athletic fit. At 6'1" and 170 lbs it fits snugly but not skin tight in a size large. Its a great piece.

Fits small compared to size chart

  • Familiarity: I returned this product before using it
  • Fit: Runs small
  • Size Bought: S
  • Height: 5'9"
  • Weight: 170lbs

I bought the following to try them all out:

Airblaster - Merino Wool Ninja Suit (M)
Fits comfy, not too tight/big but it's pretty itchy. The 350 degree zip is noticeable just trying on the suit - not sure if it'd be noticeable once you're moving though.

Icebreaker - BodyFit 200 Zone One Sheep Suit (M)
Size is a little loose but overall really comfy. The material is not itchy and it looks like I'm in a wet-suit according to my wife.

Norrøna - Wool One-Piece Long Underwear (S)
Fits snug - should have gone w/a medium but the size chart indicates a M for me would work best. Material felt nice but I liked the Icebreaker more.

Patagonia - Capilene Thermal Weight One-Piece Suit (S)
Fits well (a little snug but not tight) but wasn't sold on the colour. The thumb hooks are very tiny and just not satisfying like a full thumb loop w/material over the knuckles.

Comfy all the time

    I went with this base layer as the other one pieces were out in my size. I'm glad they were because I really love this piece. It is extremely well made like all Norrona product. Very comfortable and breathable, easy to zip, no itch.
