I need to buy a set of non-insulated and insulated boots. Does anyone have any experience with Guide Gear footwear? I see them on sportsmanguide for pretty low prices.

I am in Texas and have never really payed attention to thinsulate grams. I was thinking 600 grams of thinsulate will be good enough for days that are around the low 20's.

If anyone has an opinion I would appreciate it.
