$30 · Drysuit insulation

I have two full- suit fleece insulation for under your drysuit. They are both approximately the same size. It says size 8 on one of the two suits. I'm 5'8'', 170 lbs. and they are both a bit too snug on me. One (black/dark blue) is a heavier weight ($30.00) than the navy blue/grey one. ($25.00) or both for $50.00.
