The Kelvin series is a well-rounded collection, offering the hunter lofted insulation for any hunt or time of year, featuring Primaloft’s finest insulations in thoughtfully designed hunting garments. The original Kelvin series has been around for many years and has been a go-to staple as my primary insulation for those hard core hunts when sitting and glassing for extended periods of time in the extreme cold.

The new Kelvin Lite series adds an entirely new level of depth when it comes to insulation. This series has multiple pieces and all have their place in your outdoor arsenal.

The Kelvin Down Ultralight jacket is an ultralight and extremely packable mid-layer piece of insulation. It is packed with 3.2 ounces of 750 fill-power Primaloft Gold Down Blend insulation, which consists of 30% Primaloft and 70% Water-Resistand European Goose Down. That is a big mouthful of words to let you know that this piece of gear will keep you extremely warm and will compress down to nearly nothing when you stuff it into your pack. The insulation properties of this jacket will perform very well even when wet. The outer fabric is made of 20 Denier Rip Stop. It has two zippered hand pockets and zippered chest pocket which doubles as a stuff sack for the entire jacket. This is the ultimate minimalist type of jacket which you should never be without.

The Kelvin Lite Hoody is another lightweight dynamo in the insulation category of the Sitka line. It’s insulation properties are the Primaloft Silver Hi-Loft 80 G/M2. It has four- way stretch side panels which provide for great mobility as well as breathability. The form fitting hood allows you to keep your head and neck warm on those early morning fall days yet still provides you with good peripheral vision. The outer fabric is made from the same 20 Denier Rip Stop as the Kelvin Down Ultralight jacket.

The Kelvin Lite Vest is another piece of the insulation puzzle you won’t want to be without. Even more packable than the other pieces, but a great addition to the layering system. Combine the vest with either of the Kelvin jackets and you can regulate your body temperature to be comfortable during most of the fall weather you will encounter.

The Kelvin Lite series is essential to the hunter who spends a lot of time in the woods and especially when the difference between early morning and evening temperatures can sway as much as fifty or sixty degrees. This line will keep you warm and comfortable when it’s cool and pack down to nearly nothing when it’s “Go Time”.
