You sure have done your home work, Carhartt's & Iceman you will be very warm! The best time to buy is late in the cold season .... But then you can't allways find the size or style that want or need! If you want them, pull the trigger they will last along time "if you take care off them",I have a pair of Iceman that are over 20 years old and show very little wear, and yes they have been used a lot. Good luck with your shopping!!
