Amazing
Boyfriend's a plumber and has to work outside even in the cold New England winters. He's said they're fantastic, even to the point where they may be TOO good at keeping him warm where it's almost sweat-worthy. Overall he's recommended them to others, so they're a definite 10/10! A+ gift

Perfect cold weather bottoms.
I love these bottoms they are extremely warm and incredibly comfortable. They are a little tight to get on and especially off around the ankle but this is not a problem for me considering how warm I am in cold weather. I would recommend these to anyone trying to stay warm and comfortable while still have that nice Carhartt look.

Won’t buy any other base layers but these!!
I live in the northern Midwest where the temperature can get pretty low and these keep me warm no matter what. Strong and warm fabric will keep you warm no matter the temperature. Will be buying more in the future!

Looking to purchase Base force Extreme Super Cold Weather Bottoms. His waist of his pants he wears is a 38” that are a “little” big and his inseam is about a 29”-31”. What size would you recommend I purchase for him? Thanks!
A shopper on Jan 12, 2019
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?

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:
