I had a Kelvin light jacket (non hoody) in the open country and loved the jacket but I wanted a hood so I bought the new Kelvin light hoody. It's way bulkier and the fit is not like the old ones it's really tight in the arm pit. I'm going to try and send it back and try an XL tall even though my old one was a large.

Great insulation piece for active hunts, glassing or sitting around camp. True to size, only reason for 3.5 stars instead of 4 is the length of the jacket feels a tad short. Back of the jacket is just below the waistline and front of the jacket sits even with belt.

Love the pattern, material, and the hood. The fit just doesn’t work for me. I have an unworldly amount of Sitka gear, but the fit on this piece is just disappointing. 6’, 185, athletic, and the armpits of this one are killing me. Very tight and bunched up under the armpits. I can’t wear it and will have to try to sell it and maybe try the Kelvin Active.

This is one of the most useful pieces of kit I own. The warmth for weight is amazing and it does stay warm when wet. Packs down to nothing and can be deployed for those long glassing sessions, great in a frozen base camp, layers up very unobtrusively due to the slick fabrics. It allows you to reduce gear on the mountain as it can serve multiple roles.

I’ve solo hunted multiple days for elk, deer, and black bear in the Colorado fall weather and this jacket is clutch. It’s very breathable during medium/high exertion. When glassing and it’s cold and/or windy I put my rain shell over the top and stay warm. I wear this as a second or third layer depending on conditions. The arms do get a little tight when layered,but once all the layers are adjusted it’s comfortable and moves well. The hood is nice and warm and shaped so the sides don’t get in the way of glassing. I wish there was a way to stuff the jacket into a pocket like many ski and mountaineering jackets. This would make it easier to store in my pack.

I will agree that the sleeves and cuffs are a little on the slim side for layering, but this thing is awesome. I find this is my go to for almost any hunt. It does a great job blocking wind and keeping me warm. I was a little worried about its durability, I crawled in the sagebrush for hours slaking elk. I thought the elbows would be shredded when I was done, but not even a scratch. Even had some rain, and I stayed warm and dry.

Love this jacket. Its my fall and early winter "daily" jacket. I have also taken it into the woods hunting when temps were colder than expected and I needed some extra windblocking breathable insulation.

Just got one for Christmas from my son. I was always wearing his it’s a bigger camo one and I love it. But I didn’t want camo and he was able to get me a solid color from his store so I can wear it anywhere. I can’t believe such a light weight coat could be that warm. I live in one of the coldest places in Pennsylvania right now it’s 1 degree below zero wind chill and I’m comfortable with just a long sleeve T-shirt and a light flannel amazing.

I was ecstatic to throw this piece on over a.long sleeve merino shirt to scout on a sunny 46 degree day. The wind stopper technology along with Primaloft insulation made me perfectly content with the minimal layering. If you are an active hunter you should definitely have no problem using this as an outer layer during late season. Tree stand guys might need to throw something over on long sits but the snug arm fit make it great for an insulation piece too. One thing I would ask Sitka, are pit zips possible?

Man, what a change from the last Kelvin lite jacket! This this is like wearing a soft pillow and fits like a glove. I will say, the cuffs took a little getting used to because they have more of a contoured fit but this will be my go to jacket for sure. Sizing wise I'd say this jacket runs on the slim side as advertised. Having said that, wearing anything more than a mid-weight or traverse like later will cause the sleeves the tighten up. This is a great piece for its intended use!

Should be able to give 5 stars. Primaloft synthetic insulation just cannot be beat, and the way Sitka incorporates it into their pieces is functional. The Kelvin Lite series has a place in every kit. I carry it everywhere from the Chugach Mountains scouting for sheep to the timber for Moose, and everything in between. The overall fit and hood are functional. This is a piece for everyone's gear kit.

I used the Kelvin Lite Hoody a bunch this elk season. It was the insulating layer that I packed 90% of the time. The warmth to weight ratio is really high on this piece, it also packs small and takes little space in a pack. Almost every time I stopped to glass, snack, take a break-I broke out the Kelvin Lite. It would be layered over a Lwt Core or a Lwt Core and a Hvywt Core. The hood is well constructed and adjustable- I've owned too many hooded garments that didn't have an adjustment for the hood- they have all been sold. Down makes for a great insulation piece, but often hunting involves wet conditions- in wet conditions I want synthetic- the Primaloft resists moisture much better than down while still providing good warmth for the weight. The Kelvin Lite Hoody has a found a permanent spot in my hunting pack. I'm probably going to spring the Kelvin Lite vest for early season hunts.

This was a fantastic addition to my gear. I was skeptical before talking to the people at Sitka. For such a thin and light jacket it really delivers. I wore it alone in moderate temps and under the Jet Stream for colder temps. It is a fantastic insulation layer piece. When driving an ATV to our spot the hood really came in handing to keep my neck warm and was fantastic when glassing with the wind at my back.

Large fits perfect. 5'11" 170lbs. Tight enough to put under outer layer/rain jacket, but loose enough to put a fleece underneath if need be. Exceptional warmth to weight ratio. You won't be disappointed. Used in BC from Sept. to Dec. via Rookie Hunter Podcast. Cheers!

Alaska: It kept me warm while worn under my Cloudburst shell as part of my layering system on my caribou hunts in September and as an outter layer when temperatures dropped into the low 30s on my late season Moose hunt in October...this jacket performed flawlessly.

One of my all time favorite sitka pieces, its a perfect layering piece to my dakota jacket for the bitter cold Wisconsin late season

this fits me well. the cut of this jacket matches my body shape. the hood is cut perfect to fit around a baseball cap and does not need any pulls to make fit correctly. The sleeves are narrow at the wrist so a big watch like a suunto core may need a lil work to get it in and out of the sleeve as there is no wrist adjustments. the side panels that goes along your ribs (aka 4 way stretch) is not wind proof. I was able to blow hard with my lips on the fabric and feel my breath easily on the other side. Again this is not advertised as a windproof article but a good thing to know. over all i love how minimal this layer is and excited to add it to my layering system.

Not much needs to be said: Its ultralight, primaloft,and has a hood. Kicks but in the high country of Montana!!!!!
