Wetsuit vest is a version of wetsuit top. It is made out of neoprene usually 1 millimeter or 1.5 millimeters thick and it will keep you warm in the summer winds, clouds or bad weather. The only difference is that wetsuit vest does not have any sleeves. Why is that good? For paddling! Your arms will feel like you are just in your boardshorts but your body will stay warmer thanks to wetsuit vest.
The normal temperature range for a wetsuit vest is the same as for wetsuit top – somewhere between 72F–77F (22C-25C).
