Ultra-Thin Merino Wool Apparel

Colorado-based merino wool apparel label Smartwool recently launched a new collection of ultra-thin base layers. The collection is made from high-quality natural merino wool -- a renewable fiber that works to regulate your body's temperature to keep you warm in cold weather. Thanks to its porous texture the wool is breathable so wearers can stay warm and dry while moving outdoors.

Smartwool's Fall/Winter 2019 was crafted to be both functional and comfortable, with sizing offered for men, women, and children. The men's styles include the Intraknit Merino 200 Crew -- a lightweight, non-restrictive crewneck for winter activities; the Merino 250 Base Layer Pattern Crew - a refined base layer that offers a chafe-free seam construction; the Merino 250 Color Block Hoodie -- color-blocked hooded sweater with set-in sleeves and shoulder panels; and the Merino 250 Base Layer Pattern Bottom and Merino 250 Base Layer 3/4 Bottom -- the ideal layering piece with a covered elastic waistband and flatlock seam construction.

The women's styled include Intraknit Merino 200 Bottom -- a legging with targeted knit insulation and ventilation help keep you warm and dry; the Intraknit Merino 200 Crew -- a minimalist-style crew with gender-specific ventilation; and Merino 250 Base Layer Pattern 1/4 Zip -- a high-neck sweater with chafe-free sea construction.
