Sitka Kelvin Lite Down Jacket

Excellent layer. Worth the investment.
(Of note, this is a perfectly sized jacket, neither a baggy-fit, nor a snug fit. Just right. A large fits me perfectly, and fits under a Cloudburst Large jacket perfectly too. If you want a jacket with lots of extra room, size up)

This jacket is the perfect fit for layering. I prefer a little more roomy fit so an XL was just right for going over my other layers. Warmth to weight for this jacket is great. I agree with the other comments about noise, would be great if it were a quieter fabric. Will be a staple in my pack.

So far only tested it out on a couple coldish nights in the back yard around 25F. Have no doubt it will be warm and a valuable layering option. I could only keep it on for a few minutes in the house before starting to overheat. Build quality is great, as I would expect from Sitka. I generally wear a large in Sitka and this fit as expected, with room to have the Jetstream jacket or Traverse Hoody underneath . Only complaint is the fabric is a little noisy, but I mostly plan on using this for glassing and maybe some tree stand sits, and around camp....not likely to make any stalks in it. At this point, hard to say much about durability or if the insulation keep it's loft....time will tell.

Worked great on my elk hunt. Works well with my layering system. Kep me super warm in snow storms and negative temps

I used the jacked for chasing elk second rifle in Colorado, temps above 10,000 feet where around -20deg, 50+ MPH wind and 1.5 feet of snow. With base layer, Traverse zip tee, Traverse cold weather hoody and this Kelvin Lite Down Jacket I never once got cold!
I love how lite it is but still so warm and compresses down very small in your pack when not in use, perfect as an outer shell when stopping to glass.
Would buy again, Thanks GOHUNT!
