Very nice parka pants

Everything was great. Very nice Air Force parka pants. Shipping took a little while but not long enough to fret about. The suspenders was an added bonus.

aviation/airman pants

I ordered size 34 and they fit perfect with adjustable back strap also. I wear 33-34.
The padding and insulation is spot on, excellent wind protection and warmth! I wore them on top of my jeans, plenty room. Also the zippers are easy to operate and u can keep your shoes on, just open the side bottom leg zipper. Mine came with suspenders! You can wear without but its better to have them. I ordered these because I fly a power paraglider and needed insulation and wind protective clothing, you will not find anything better than these for $38! These are aviation military proven clothing!
Highly recommend! Very comfortable and clean right out of the box! Some minor spots here and there but who cares! Well constructed!
I am considering using them for hunting.
