What it is made of

  • 17.5 micron merino190 g/m²

    Fine enough not to itch on a neck; heavy enough to be a real layer.

  • Nylon core spun13%

    Wrapped inside the yarn, not blended over it. Doubles abrasion life.

  • Flatlock seams

    No raised seam under a pack strap.

The full description

This is the layer that touches you, so it is the layer where fibre diameter matters. At 17.5 micron it does not itch on the neck, and at 190 g/m² it is a genuine insulating layer rather than a summer t-shirt in wool clothing.

The 13% nylon is core-spun — wrapped inside the yarn rather than blended alongside it — which roughly doubles abrasion life at the shoulders and elbows where a pack works against it. Flatlock seams throughout, and the shoulder seams are moved forward off the strap line.

Wool is here for one honest reason: it stays wearable when it is dirty. On a multi-day hunt that is not a comfort feature, it is the difference between one shirt and three.

Bought for

Every hunt in this catalog, as the first layer.

Not for

Hard brush work with no shell over it — merino abrades faster than a synthetic, and no warranty covers that.

Field notes

  1. 01Wear it against skin. A synthetic layer under merino cancels most of what you paid for.
  2. 02Sizing runs true. If you are between sizes and layering over it, take the smaller one.
  3. 03Wash cold on a wool cycle and hang dry. A hot dryer will shrink this by roughly a size, permanently.
