4th element artic buoyancy?

[StreetDoctor]

Better late than never, I forgot to reply. My Artic undergarments (with an underarmor base) require 24lbs to sink with my TLS350. Drysuit alone, no rig. I think they'll be good for me from mid 40's to high 50's. Get's a little warm in 60 degree water depending on what you're doing.
