Cold-slaying assassin.

The Airblaster Women's Merino Ninja Suit places all other baselayers in a chokehold and makes them cry for mercy. Whether you're a femme-fatale freestyler or an apprentice learning the ropes of the alpine dojo, you will appreciate the wonderful warmth, superior moisture management, and funk-fighting skill set of the miraculous merino wool fibers and fabulous four-way stretch Lycra material.

Merino wool is renowned for its insulating properties, extremely soft feel, and natural odor resistance, and it's blended with a touch of Lycra for extra stretch so you can move freely. The fit is next-to-skin to help it wick moisture more efficiently, and the cut is women's-specific for comfort. A seven panel form-fitting hood covers up your dome on extra cold days and thumb holes in the cuffs prevent snow from getting in your sleeves. There's no need to worry about what happens if you need to use the bathroom when you're at the mountain—a 350° waist zipper makes it easy to take care of business without having to completely undress.

  • Merino wool Lycra blend
  • Naturally antimicrobial

Happy Wife; Happy Ninja.

    XL fits. Its warm. Its comfy. It looks good. Its a cool item to be wearing in cold weather. Its merino. Its a no brainer to have this in the wardrobe.


    Amazing warmth and comfort

    • Familiarity:I've used it once or twice and have initial impressions
    • Fit:True to size

    I like to see reviews before I buy something unknown to me, and there weren't any for this Merino wool Ninja Suit onesi yet but I had been looking for a onesi/one-piece long underwear for a while.... since this one was Merino wool, thus having the most promise for warmth, I bought it. It is not the most inexpensive of the onesi's out there -- but it is worth EVERY PENNY!! Hard to believe I'm so enthusiastic about long underwear, lol! But I spend all day outside on a farm and am always cold despite bundling up... and, I ride horses and can't wear something like the warm one piece Carhartts, so this type of long underwear has been on my wishlist. Yay :)

    I'm probably between a small and a medium, but I got the medium because I didn't want something too tight or form-fitting, as a little "room" seems to be warmer as it traps the warm air. The medium fits me great. The Merino wool is thin, stretchy and super soft - I had NO ITCHINESS at all wearing it all day, I was surprised. Soft, no itch = super comfortable.

    I wore it for the first time yesterday...granted, only one time so far...but it was a very windy, cold day (high 20's F with a strong wind, so I'd say more like low teens)so it was a pretty good test. I was perfectly warm. The one-piece long underwear concept is that there are no gaps for air or wind to get to you, and that is precisely what makes me cold. I put my socks on over the bottom of the Ninja Suit too. I didn't use the hood yet (MORE warmth!) but I tried it and like the rest of the Ninja suit it fit and felt great for when I will need it.

    I used the thumb loops to keep my hands and wrists further protected from wind and air. And perhaps the best things about the Ninja Suit was the very well-designed 360 degree zipper for bathroom runs. No awkwardness in its use or design, bonus!

    I highly recommend this to anyone looking for easy, comfortable warmth during any winter activity.
