I bought this for sleepwear. I know from my other 150g wool that they don't do well as a stand alone garment. (At least not the cami since you can't hide bra straps.) This was so comfortable it couldn't be contained to pj status. With the adjustable straps and it's awesome feel it started layering it under sweaters and then just about everything. When I saw these on sale at Moosejaw it was a no brainer to order another. It is my go to piece for camping. With the merino wool it wicks so well and dries fast if I'm caught in the rain. Layer up as needed, strip down to it for sleep and I don't get chilled if I have to wear a damp piece while it dries.
