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.

Biberall extreme weather wear
Great purchase! The overalls are extremely warm and waterproof. They are so easy to put on and zip up. The design leaves no exposure to cold or moisture getting in. This garment is consistent with every Carhart purchase that I have ever made. Great product and also a great value (I would have paid more for it) As I live in the Northeast US, I have already had many opportunities to put to test in heavy snow, wind, rain, and ice.

Great Bibs?
Extremely warm. Zippers to thigh and upper front zipper makes them an easy on/off while wearing work shoes. Carhartt quality. I am 6"2" and had to adjust the suspenders all the way up on the regular length bibs. I suggest you try on a pair to find the right length for yourself. Great bibs.
