Your cozy adventure companion. Airblaster exclusive Merino blend fabric is one of the softest wool blend ever encountered, thanks to the marriage of Tencel with ultrafine 19 micron brushed Merino fibers. Add the warming protection of one-piece design, and you have the finest base layer available! Airblaster only uses non mulesed wool from New Zealand and Australia, so you can feel as good about owning this Ninja Suit as you do when you’re cozied up inside of it.
