Not much to add to what has already been said. I did have to pay a seamstress to add a stretchy piece on the inside of both forearms. With that done, I think they will work quite well for early season hunts.
Husky,
I've hunted in a Sitka primaloft Kelvin Vest for two years and used a KUIU superdown 1/4 zip tee this year. I've used them both in some pretty cold weather but wasn't terribly wet. I use a superdown hoodie for my everyday jacket right now to get me through the winter. I'm a fan of both...
I use the walkstool 55 and I really like it. I used it all season last year and will definitely use it going forward. It is made in Sweden and is definitely tough enough for extended field use. I also used the chair without the telescopic legs extended a lot more than I expected.
I have the Kaitum 3 and I think it is great. I've had it in sub zero temperatures and in nasty, nasty Wyoming wind. I think the dual vestibule is worth every penny. We use the uphill vestibule for entry/exit, water and boot storage. We use the downhill vestibule for our packs and bows.
So I was telling my wife about the new improvements to the slick bag and watched the color drain out of her face. Yeah, I'll be calling tomorrow to see if I want to 'adjust' my X-mas order and hold off on my slick bag until the 2014 version is available.
