    Good layering for the LFOC.

    Nice gear put way over priced.

    I like the design. Fleece is cheaper but merino is ideal for layering. I’m considering this as a purchase next winter

    Does anyone have any actual experience wearing FirstSpear’s ACM line? I need to replace some very old Merino items and I like this line of clothing. My biggest question is; with the polyester against the skin and wool on the outside, does it begin to stink after a few days like all other polyester undergarments?

    Thanks in advance to anyone who can help.

    Take care,

      I have both the Mid shirt and Hoodlum hoodie and have worn both for over a year now. I have not experienced any sort of smell whatsoever with the poly material combo especially on days when I was sweating more with fluctuating temperatures. A great tip I have learned is that you really don’t need to wash these very often either because they don’t stink up easily, you will be surprised how fresh it smells after hanging it outside for a day. Highly recommend the wool line from FS.
