So i'm looking to pick up a new wetsuit. I have a 4/3 Rip Curl Bat Wing and its wayyyy to small (xs), Im looking for some advice on sizing, brand and thickness.

Height: 6'0
Weight: 150 lbs
Waste: 31 - 32
Surf Location: Momouth County, New Jersey
Time of surfing: All year round (mainly summer and winter)
Price Range: $150 - $275 (college budget not trying to spend an arm and a leg)

- Doesnt need to be too technical - just want it to keep me warm in the heart of a Jersey winter, but not over heat me in early spring or late fall.
