Tiburons are great for early season and hot Oct and Nov hunts. They are super light weight and less bulky than others. When climbing super steep hills they are great with less resistance. In fact, it almost feels like I don't have any pants on! They also have vents on the sides that allow even more air circulation.
Similar to winter hunting, layer if needed. It's pretty easy to pack a thin set of long johns if it's cold in the morning/evening. If in a rainy area pack breathable rain jacket and pants.
