Polartec Drysuit Liner $49
 

Here's a possibility for somebody who wants value in a drysuit liner:
the LL Bean Polartec PowerDry Union Suit:

Only $49 (tall $54) versus $80 for the NRS union suit (polyester)
and $98 for the Kokatat drysuit liner (Polartec 100). PowerDry is
my favorite fabric for warmth, wicking, quick-dry, and durability.
Possible downside is buttons instead of zipper.
