I live in a warm part of the country and used the Base Force Bottoms and Tops in 20 degree weather with a steady 15 mph wind. After standing in a location for 3+ hours, the base force kept me from freezing but I’m not sure how it would perform in extreme cold. They were very comfortable to wear all day long, they breathe well when I went in doors and did not cause me to sweat. Overall, I would recommend them.

Great quality - as expected
I bought this to replace older thermal bottoms, and this was a SIGNIFICANT upgrade to the regular thermals I have been using for years. I went through 2 of the coldest days of my life in the northeastern U.S. and I felt no pain with these on. Cannot recommend them enough.

what is the name of the warmest base thermals?
A shopper on Jan 4, 2018
BEST ANSWER: We recommend either our Base Force Extremes Super Cold Weather Bottom (102349) or our Base Force Cotton Super Cold Weather Bottom (100640).
How does the super-cold cotton bottoms compare to the super-cold polyester version in use? This description makes cotton sound the warmest, a polyester comment says poly is warmest, except for the Insulated Yukon. What is warmest for sitting in a chair in a cold room all day?

Carhartt Base Force Extremes Super-Cold Weather Bottom
Carhartt Base Force Extremes Super-Cold Weather Bottom
Carhartt Base Force Cotton Super-Cold Weather Bottom
Carhartt Base Force Cotton Super-Cold Weather Bottom
BEST ANSWER: I cannot tell the difference
I have your k223dpo heavy bottom, which has been discontinued,what is the equivalent?
irving d on Jan 31, 2017
BEST ANSWER: The closest replacement would be style style 102349.
Will the heavyweight thermal bottoms block out high speed wind?
A shopper on Jan 28, 2017
BEST ANSWER: These are not specifically advertised as blocking the wind, but they will help to some extent.
How do they compare to the under armor 4.0 base layer? I wear those during winter because I'm a mail carrier.
A shopper on Jan 7, 2017
BEST ANSWER: We cannot compare them to another brand's product. However, these are great pick for warmth and quick-drying technology.
95% Poly; 5% Spandex?
A shopper on Dec 20, 2016
BEST ANSWER: This style is made of 8-ounce, 60% polyester/33% Cocona® 37.5® polyester/7% spandex.
should I order by the waist size/inseam of regular pants (size 32/32)? I usually buy a size up for ease of movement.
Deb F on Dec 17, 2016
BEST ANSWER: We would recommend a size medium regular.
What is the temperature these are rated to keep you comfortable down to?
A shopper on Oct 31, 2016
BEST ANSWER: We do not temperature rate our garments because everyone has a different threshold for what they consider to be warm. This style is for very cold weather.
are these those thin satin-y tight fitting "underarmour" stuff that pedal bikers wear ? ive bought "thermal" before from carhartt only to get what amounted to a t-shirt
jon n on Oct 17, 2016
BEST ANSWER: This style is designed for super cold weather, it is the warmest thermal we offer other than our Yukon Quilted Base Layer Bottom Style 102315 that is thicker, heavier and insulated. The link for this item is below:
