How to Measure

Diagram showing where to measure chest, natural waist, and hips.

CHEST:

Measure just under arms and across shoulder blades holding the tape firm and level. If your chest falls between sizes, order the next size up.

NATURAL WAIST:

Bend side to side and find the natural bend in your body; this is your natural waist. Note: It may not be the smallest point.

HIPS:

Measure the fullest point between your natural waist and crotch.

Note: For best results measure over your undergarments. Use a cloth measuring tape.

Fits

Relaxed Fit: closer to body Loose Fit: ease at body

Light and warm
This is the right one for me, the big feature is how light it is while being as warm as it gets. I tried other jackets like the Montana and it's too bulky. Feels like a fashion piece while I can shovel snow, drive and do anything in this. I'll buy another one when I need to.

Clean and warm
This is a clean ahh jacket heavy duty I work on hvac so I be up In the roof in the Dallas skylines all the time and is getting hella cold down here in the south, specially up there in the roof where that wind hits your harder so far this jacket been a monster against the wind and rain I only need one layer underneath and it keeps my warm exactly what I was looking for and on top of that carthartt I gotten compliments on looks with it I honestly thought it was a little overkill when i bought it but being up there in the roof where that cold wind really hits you changed my mind and now I love it The only one thing that I would call a con which to me don't really bother me others might is a very crunchy jacket it makes a lot of sound when you move lol.
