SITKA Gear Kelvin AeroLite Puffy Jacket

This lightweight, extremely compressible hunting puffy keeps you warm, without the bulk that typically comes with puffy style jackets. Whether you put it on when you sit down to start glassing, or use it as your outer shell on those late season hunts while slowly creeping through the timber, the Kelvin AeroLite is one of the most versatile pieces in the SITKA lineup. With virtually no bulk, it also fits comfortably under a shell whenever you need an extra layer of warmth.

It doesn't matter how it happens, but it happens. You get wet unexpectedly when you are out hunting. Maybe you slipped crossing the creek and half your arm is now soaked, or maybe you are moving through the timber as the sun melts snow high in the branches above, showering you slowly throughout the day. Synthetic PrimaLoft® Gold Insulation with Cross Core™ technology acts like down insulation, but unlike down, it will hold in your heat even when it's wet. That's a critical feature when you're five miles from the truck, or out for an extended multi-day backcountry hunt.

The Kelvin AeroLite Jacket Fit: The AeroLite is a Standard Fit, designed to be used in a larger system of layering for more versatility from early to late season conditions.


SITKA AeroLite Jacket Features:

  • Synthetic PrimaLoft® Gold Insulation with Cross Core™ technology replicates the warmth and compressibility of down, but with the benefit of warm-when-wet performance

  • Lightweight insulation (35% recycled) is infused with silica aerogel, a nearly weightless material that’s composed of more than 95% air and acts as additional thermal insulation

  • 20-denier polyester face with durable water repellent finish, 20-denier polyester backer

  • DWR finish sheds light precipitation and prevents outer fabric from soaking through

  • Gusseted stretch cuffs allow for smooth, easy layering and unrestricted shooting

  • Fitted hood provides low-profile warmth and concealment; while making sure you can see animals coming in from all directions

  • Deep, zippered chest pocket safely stores your valuables like a range finder or phone

  • Weight: 1lb

Here's why SITKA made the Kelvin AeroLite Jacket

SITKA realized that traditional down puffy jackets had certain drawbacks; while warm and packable, they quickly become useless dead weight in your pack if they get wet. Their goal was to create a versatile synthetic insulation that will keep you warm while standing up to mountain environments, which usually involve moisture in some form, all in a lightweight, compressible package that doesn’t sacrifice movement or breathability.
