20-50 degrees
Used them for elk in Nov paired with all wool pants. I found that they have been a good combo for 20-50 degree range, keeping warm when needed and breathing well when warmer weather arrives later in the day.

Bi Component
The Bi Component crew is a no-frills cold weather base layer. Its length is perfect for staying tucked in during all day activity. Layering the Power Stretch Fleece on top and you will not be getting cold. These guys get it, make practical clothes in the USA and offer them at reasonable prices! I highly recommend this company!

Bi Component
The Bi Components line up is solid. Made in the USA is a nice feature and the pricing does not reflect the country of origin.
