    The price is reasonable on these shirts, but the image on First Spear has that huge gross image on the chest, they need to get rid of shirts with that huge logo.

      That’s also my question. The image here shows a FS logo on the front, which works for me. The image on the website shows a printed image, which does not.

      There is no click down choice.

      Which one comes on this shirt?

    • FS says:

      Gerard the images have been updated for the long sleeve field shirt. Short sleeve field shirts will be updated in just a few weeks. Thank You!

        Thank you for that information, both the short & long sleeve field shirts will be a future purchase for me

    I got one of these in long sleeve (I only wear long sleeves in the field) to try out shortly before they came out. The idea was that if the performance was good, perhaps we’d (HPG) carry them ourselves. The main reason for us to stock them was to get them without the huge demonic image on the chest.

    Folks who know me know that I don’t have a very high opinion of wool based on lots of time with it in the field. It still makes no sense as an insulation layer (warmth to weight and warmth when wet is abysmal compared to primaloft and a bunch of others), but as an inner layer I thought it could be good if properly designed. I saw that this garment was built the right way — synthetic on the inside bonded to a wool outer layer. In theory, this would minimize all of the downsides of wool and maximize what it is good at (drying VERY slowly so as to mitigate evaporative heat loss next to the skin).

    It’s a little bit of a misnomer to call this a wool garment because it actually has a higher synthetic content than it does wool, but I’m here to tell you it flat out WORKS. The wool in the outer layer wants to absorb water while the synthetic in the inner layer wants to get rid of water. This push / pull effect means that this garment pulls sweat off of the skin quicker than anything I’ve ever tried. Of course the wool outer layer stays wet longer than synthetic, but the inner layer next to the skin gets and stays dry. It doesn’t take too much horribly longer for the wool outer layer to dry than comparable synthetic — perhaps double the time. And because the outer layer dries so much more slowly than synthetic, there isn’t much evaporative cooling taking place.

    It didn’t take too many days using this before it became my go to baselayer. It got to the point that whenever I reached for a synthetic baselayer just to keep doing A/B testing, I’d get a little bit of anxiety and end up grabbing this baselayer because I already knew which one was keeping me drier and warmer.

    This has stood up to accidentally being thrown in the dryer a couple of times without shrinking. However, it is pilling on the outside quicker than comparable synthetics. Not in a way that would effect performance, but it’s worth mentioning.

    FS – stand by for an order, I need a couple of these without the demon.

    Does this shirt need to fit close to the skin to work? And how is the cut: slim, oversized, etc? Hard to get the right fit online with no try-on.

      Sizing is on the trim side. I sized up to get my normal t-shirt sizing (big enough to mostly conceal a pistol IWB, but not huge and loose). On the other hand, the one in my size wasn’t too small and gets some use. It probably works better close to the skin, but the little bit of looseness I prefer doesn’t seem to limit effectiveness.
