Why We Like The Outdoor Research Alpine Onset Merino 150 Bottom
The higher the elevation, the cooler the weather, so we reach for the Outdoor Research Alpine Onset Merino 150 Bottom for our all-season summits. These lightweight merino wool bottoms offer just-right insulation, wicking moisture management, and natural anti-odor tech for year-round adventuring. Updated fabric is extra durable and stretchy, thanks to polyester and Lycra fibers, and a gusseted crotch increases our range of motion further to help with scrambles and skin track ascents. Flat-lock seams make the next-to-skin fit chafe-free to keep us active throughout the seasons.

Warm moisture wicking layer
For how thin it is, this offers a nice first layer to regulate moisture wicking when layering clothes. I’ve used them for snowboarding and hiking in colder climates and found they work great and are very comfortable. It’s not the softest material but I personally don’t mind the texture.

Lightweight yet warm, and avoids picking up odors after being worn a couple days in a row. I picked this up for a 6 day backcountry trip and it served me well in 40-50 degree weather.

Base layers
Works well under uniforms. Wasn’t too thick to hinder the fit.

Disolvable
Turns to powder when wet. It is unwashable, even by hand.

Good upgrade from previous generation base layers
Really like the improvement to this base layer with the addition of the merino blend. It feels better next to skin and I think it actually moves moisture and dries faster with the merino compared to the other OR base layers I have.
