Made in Finland by people who know how to stay warm when it’s cold, this is the best next-to-skin layer in the world. Polypropylene is widely known as the best wicking fabric, but even with traditional polypropylene you can feel periods of damp chill when your body builds a layer of sweat or you simply get wet. But with the Airbases big air pockets, you have nothing contacting the majority of your skin surface, while adjacent polypropylene wicks moisture, so you always feel dry. You can wear pretty much anything over the top of it and feel comfortable and dry, in any weather. And if you’re out on a day that gets hotter, you simply expose the base layer and, voila, you get instant full-blown cooling. So you can literally wear this stuff right into a warm day, and regulate your temperature more easily than with any other garment. Made of polypropylene with silver ion scent control. Shirt has knit collar and cuffs.

Great but.....4.8 of 5

So I got this and thought fish-net why the hell not the Europeans do it (worked with their militaries). This stuff is awesome....I give it a 4.8 stars bc the sleeve material is so not bulky that slipping a light merino shirt over the top it bunched on my forearm and I had to fish for it. I’m going to sew in some gutted 550 cord for thumb loops just for this (probably make em long enough to clip mitts to so when I have to fumble with a god I don’t have to put a glove in my mouth or shove it in my F1 hip belt)
I used it in MS, damp and chilly, walked to a tree about a mile then had a difficult climb (meaning I sweat a bunch). All I did was zip down the 1/4 zip on my merino and oh the freshness. And fast. I wasn’t wet for the remainder of the sit and didn’t require the outer layer I’d thought bc of the insulating fishnet I had. Wow, gifts for all serious hunters in the family. Plus this stuff is super packable and I had washed it and dried. Seasons will tell about durability but I can say if it’s anything like every piece of Eberlestock gear I’s gonna last! Thanks Eberlestock for fantabstic products for the pursuit of adventure in the homeland and on the battle field. You guys rock.

Great product

I really like these, although they’re a bit pricey. I’m of the “buy once cry once” school, they’re worth every penny!!

Airbase top cut too Short to be functional

I engage in a number of strenuous activities in Montana during the winter including skiing, and hiking. The balance of warmth and sweating is always a battle. The Airbase system has done a great job delivering this balanced warmth. One VERY important note however; I wear an XL in almost everything I wear and ordered an XL set of Airbase tops and bottoms. They both fit well EXCEPT the top was FAR too short for a typical XL person’s frame. For a base layer like this, if anything, one should error on having the top be a bit long. The Airbase shortness in the top makes it very difficult to use effectively.
