Well Double, I spent about 500.00 tostay warm (counting two base layers) and dry if I add up what I wear, but its not bulky and it will last for years as my last set did that I finally retired after 10 years of use. Cabelas thinsulate dry plus fleece. Everything I have is gortex or water proof and can handle temps below zero. I've been hunting in 10-15 degree temps this past 2 weeks... Its worth the money to me.. I hate being cold and or wet.
