Just like the title says. RS Taichi inner suits. One of them is the standard one with the wicking fabric. Lightweight, comfy and cooling. Second one is the windblocker version. I'm from Oregon, so this was mandatory for the cold days. Blocks all the wind from getting through your perforated suit and keeps you warm on cold days. Both are size 44. $35 for the regular one and $90 for the windblocker. Both are laundered. The Windblocker does have a spot on the chest, not really sure what it is or how it got there. But no smell or anything and the fabric isn't compromised at all.
