Well im a big believer of under armour. Almost everthing i wear in the woods is under armour. Its all fitted so it fits me well there fore i dont work as hard movin around and i sweat less. Its spensive but the stuff is really hard to beat. I save a little money every year an try to hunt up some older made in usa stuff to. I wear a 100% wool walls polar tuff jacket from the mid 80's an its like gold to me, ive got my old jerry simmons patch sowed on the left side chest of the jacket. I never leave the house during cold months without it. Ive had it aloong and there doesnt exist an amount of money that could buy it from me. Hehe when i washed it last at the end of deer season the jacket turned the water red its seen alotttttt of dead deer
