Kuiu is incredible gear for what it’s intended to be. Ultralight / packable, ultralight mountain gear. A lot of the same fabrics as the big ski companies like Patagonia, Arcteryx etc.
I still prefer firstlite merino over Kuiu however I have some of the Kuiu pro merino in the mail to try out.
The Kuiu can keep you warm stand hunting but it’s an incredibly expensive endeavour.
My upper layer would be a heavy merino base, the strong fleece 260, robust enough for walking through trees etc. I’d pack in the hooded super down pro coat for when I’m sitting. If it’s really cold I’d probably throw on the kenai during the walk.
My lower layer would be mid weight zip off synthetics, kutana hybrids and down pro pants in the pack.
Lastly, Yukon rain gear for brush pushing, extra warmth and to cut wind. (I like the new kutana rain gear better but the Yukon is more robust for brush busting).
Kuiu also just did a limited release for Gold and Platinum insiders for the “Gale Force” jacket and pants. The pants are more of a bib than anything I’ve seen from Kuiu. It’s not dedicated “white tail” gear, but it’s darn close.
Kuiu is great quality stuff but the focus is on active ultralight mountain hunts. You could put together a system for the elements but it’s not going to be super robust.
I’ve had pants/shirts/jackets shredded and wrecked but always from user error. Caught on barbed wire, walking through dense brush wearing the down coats, accidental slide on a scree field etc.
I’m still happy to take that sacrifice on durability for the benefits I get out of the gear however I’m always on the move in the back country or sitting to glass.
