The full description

A late-season sit is the hardest thing in this catalog to dress for: you walk in warm, you sit still for six hours, and the temperature drops for four of them. It is solved with layers you can shed at the tree, not with one very warm coat.

This is that system — merino against the skin, grid fleece over it, wind shirt to stop convection, and the Sixty Puffy to put on once you stop moving. Plus the light to get in and out on, and the wind checker that decides which tree you sit in.

Every size is chosen at checkout. If your sizes differ across pieces, order them separately and email us — we will match the kit price.

Bought for

Late-season whitetail hunters starting a layering system from scratch.

Not for

Anyone who already owns good base layers. Buy the gaps instead — the kit is only a saving if you need all of it.

Field notes

01Walk in wearing the merino and the grid fleece only. Everything else goes on at the tree.
02Puffy last, over the wind shirt, once you have stopped sweating.
03Check the wind at the truck and again at the tree. Do not talk yourself into a marginal tree.
