I hunt in South Louisiana, and we have been having record temps this year already. This is my warm weather dress code............Trek Lite pants & Mossy Oak Leafy jacket. Under them I wear Under armour heat gear boxer briefs and a heat gear loose fit under armour short sleeve T shirt. The leafy jacket has the mesh that lets the air in well. The under armour is well worth the $, and the Trek Lite will last for years, its cool, and never fades................
