The Firn Line Long Sleeve is the perfect, cozy, winter-weight base layer. Made of super soft 100% merino wool, the Firn Line is your winter companion for sweaty backcountry skiing ascents to cool evenings getting the fire going in the cabin. Take it on your winter travels and layer it under your favorite sweater.

Great for nordic skiing, downhill skiing, winter hikes, snowshoeing, fat tire biking and running

Features Merino wool for soft, breathable natural odor resistance.

This is an official Made in Alaska product! Our products are made by us in our Anchorage, Alaska workshop.

Made in Alaska, Made in USA

Our 100% Merino wool is lightweight and breathable, but soft and warm enough to keep you cozy from the early chills of fall through the frigid temps of winter. Merino wool is naturally odor-resistant and a great natural fiber option. Our wool is ethically produced from non-mulesed merino wool sheep.

We offer fit options! Wild Iris for a more straight/square frame shape. Azalea for a curvier shape. These fit options are not "relaxed fit" and "athletic fit" - they are actually designed to fit and flatter different body proportions to give options for the diverse body shapes of the outdoor loving community.

100% Merino Wool

Weight: 5 oz (size M)
