The Celsius jacket is a nice piece of clothing.  In moderately cold weather, I'll wear one of their next-to-skin layers (wicks great--and that's actually one of the secrets to staying warm), the '07 Mountain Shirt, the vest and then the Celsius.  But when it gets really cold, that's when you'll need another layer under the Celsius but on top of the underlayers.  I hope to buy some of the Kelvin insulated line, maybe next year.  In the meantime, I can either use the 90% under this or in super cold, I'll use some of my old Winona as an insulative layer.  Nice thing about Winona is that it too stretches and form fits much like Sitka, as opposed to a lot of heavier stuff out there which is simply too bulky for what I want to do with it.

I see they've changed the lineup since I last looked at the website.  I've got to say, however, that I've found their clothing to be wonderful.  I had the base longsleeved tee and vest on yesterday, but what has impressed me the most is the ability to wick away sweat.  My son and I were on a scouting backpack several years ago in the Trinity Alps wilderness in CA when it had to be 90+ in the shade, and I was actually cool! I'm not a fan of their digital pattern, however.

The synthetics does not seem to keep you as warm below 30 degrees especially once you sit still for 2 hours.  It seems to feel very cold to the touch as layer after layer begins to get cold.  You cannot beat the synthetics if you move a little as in still hunting.  Sitka Gear is excellent for lightweight yet warm hunting clothes until the 20's or below.  I'd layer wool under it to stay warm.

In regards to Steve-os comments about Kansas being cold, yes it does get cold but being from michigan you should know its the humidity that makes it feel so much worse...I'll take -35f with 10% humidity over the crap we get.. Really I think people are underestimating the jacket with the suggestions of layering so much and wouldn't waste the money on the vest until you see what it feels like as the weather starts to get chilly, I was suprised at how warm it was all on its own

Still kicking around trying the Sitka Gear. My mainstay for the last several years has been a base layer of Under Armour followed by a layer of thermastat and topped off with a layer of loose fitting cozy fleece. In real cold weather, and it can get darn cold here in Michigan, I top that of with a light weight Gortex jacket and a pair of Gortex fleece bibs. I'm afraid the tight fitting Sitka Gear will make my big beer belly a converation piece!!! At 53 skin tight isn't what it used to be.


                   

i was thinking about getting the Celsius vest just as a good under layer for warm insulation, but without sleeves, and a good form-fit.

has anybody evaluated the vest as a good , non-bulky insulation layer in moderate temps?

what did you think?

Johnny, It would be perfect for that    

keep an eye out on camofire.com  just ordered the celsius bibs for $120 to my door.  looking forward to buying up other pieces as they become available.

Yellow Dog,

TRUST me!  If you don't do anything else, ditch those UA base layers for a set of Sitka Core.  You can thank me later.

Johnny,

The Celsius Vest may be my favorite piece.  It is VERY warm for its weight.

I'll second Steve O on the warm of the Celcius vest. I love it.
I use the Core shirt, and Traverse shirt with the vest in moderate temps. When it gets colder I add a layer of Ullfrotte Woolpower 400 sweater under the Traverst shirt. When its real cold then I add my Dayone jacket over top.
I love the Sitka material under my jackets, b/c its "slick". The layers slide along with each other. No binding/catching when I am drawing my bow.
I also love the Celcius hat. For me it's quite big on its own (at least for my head), but when the temps drop I put on a fleece skull cap underneath. Perfect fit and VERY WARM!!

I'm going elk hunting Sept 19 to the 29th in Colorado. Plan on wearing acsent pants and celcius vest, 90% jacket along with core layer and Traverse top. Is this going to be warm enough?

That sounds like a fine setup to me.
