After wearing and using Sitka gear extensively for the past 5 years this new piece has to be my favorite. It’s dead silent, light weight, very warm and packs down to nothing in my pack. I’ve taken this jacket on every hunt I’ve been on this year. On mild days I wear it as a outer layer over my core lightweight and heavyweight hoody. Then on colder days I layer it under my fanatic set. The amount of extra warmth it brings you on those extremely cold days is just what I needed! The only downfall is the face fabric is not very durable but it’s not designed as a brush busting piece. Now if they will only make these in a pant for under the fanatic bibs I will be extremely happy!

Awesome jacket, definitely my favorite piece in my system. I use it as a mid-layer or while walking in to my stand. Using it stand alone, under my stratus, or under my fanatic I have been comfortable in my stand from 60 degrees down to 20 degrees with wind so far this season.

Very warm for its weight. Does well with light precipitation. Fits true to size, I'm 6'3'' 190 lbs and a large is perfect. Main issue is the sleeves from elbow down are extremely tight and narrow so they ride up when you wear it under a shell, and this also makes it very hard to wear more than 1 layer underneath. I have worn this jacket under the Goretex rain shell and it is a pain to get the sleeves to fit right. The narrow sleeve ends also mean you have to have an over glove otherwise with normal glove you will likely have a bare skin gap at your wrist. Neck is not as tall as it should be, or it should be adjustable with a pull string which it is not so you need a gator in the wind.

This jacket is legit for its weight. I was really surprised how warm it is. I have worn this jacket in 30 degree weather with just a fanatic hoody underneath and stayed warm. It does great with blocking wind too. Will def be a go to piece in cold weather.

Fantastic addition to the Whitetail line up! This jacket is comfortable and impossibly light, especially when you realize how warm it actually keeps you, it's just amazing! The tapered sleeves are excellent for being able to easily slide your hands into the front pockets, which feels like they have hand warmers built in! I also really love the fact that you can snug up the bottom of this jacket without ever having to take your hands out of the pockets, the adjustment cords are built inside them, which to me is ingenious, and means less movement and no more dangly adjustment straps hanging around my waist! The chest pocket provides plenty of room for my range finder and release. Which the added harness pass through, this will now be my go to outer layer for most, if not all, the rest the season!

The Celsius Midi is obviously a new piece for this year so I plan on submitting a follow up review after the season. First impressions of the jacket though are incredible and I'm blown away by the functional movement married with the insulating properties of this lightweight piece. A perfect brother to the Kelvin Active for the tree-stand hunter with the addition of longer sleeves which mitigates the bunching up of gloves when the cuff meets the sleeve. Compressed sleeves for a clean draw cycle and easy layering might make this piece a new favorite of mine when October rolls around.
