The Bahia Jane is a Farmer Jane with full-length legs and a partial chest zipper. The combination of the zipper and use of super-stretchy neoprene makes this suit easy to don and doff. An athletic cut means this suit offers good mobility for paddling yet still fits snugly enough to prevent much flush-through.
For warmth in the armpits and arms, I wear a RipCurl 1mm long-sleeved shirt under the Bahia Jane. This has been a good combo for me in the "shoulder seasons". For winter wear, you'll need a thicker fullsuit or a drysuit, but in between hot summer and cold winter, the Bahia Jane provides versatility and comfort.
This is the most comfortable neoprene I've worn to date.
