Ultralight Warmth That Slips Under Your Shell

PrimaLoft® Gold Insulation with Cross Core™ technology delivers down-like warmth that stays effective even when wet. At just 16 oz., this trail-ready layer fits comfortably under a shell without restricting your draw or blocking peripheral vision. The fitted hood and gusseted stretch cuffs are season-proven details that keep you in the hunt when temperatures drop and the wind picks up.

Insulation That Performs When Down Quits

Insulation That Performs When Down Quits

Down insulation is the gear that looked impressive in the store and then clumped into useless cold spots after a rain-soaked horseback pack-in at 9,000 feet. The Kelvin AeroLite Jacket uses PrimaLoft® Gold with Cross Core™ technology — synthetic fill that replicates down's compressibility but retains warmth when wet. We don't list gear we wouldn't bet a $3,000 tag on, and this jacket earned its spot by solving the exact failure that sends hunters home cold. The 20-denier polyester face with DWR finish resists precipitation, so the insulation underneath keeps doing its job through driving rain on day six of a backcountry elk hunt.

Sixteen Ounces That Disappear Under Your Shell

Sixteen Ounces That Disappear Under Your Shell

At 16 oz, the Kelvin AeroLite Jacket is a season-proven layer that maximizes warmth without the bulk that restricts your draw or blocks your scope eye relief. The gusseted stretch cuffs slide smoothly over base layers and under a hard shell, so you're not fighting your own clothing when a bull steps out at 200 yards in heavy timber. Silica aerogel — a material composed of more than 95% air — is infused into the 35% recycled PrimaLoft® Gold insulation, adding thermal efficiency with virtually zero weight penalty. This is the jacket you wear from September elk opener through late-season mule deer, layering up or down without rewiring your entire system.

Hunt-Ready Details That Don't Get in the Way

Hunt-Ready Details That Don't Get in the Way

The fitted hood provides low-profile warmth and concealment without obstructing peripheral vision — critical when you're glassing a ridgeline and need full awareness of movement below. A deep, zippered chest pocket keeps your phone, GPS, or rangefinder secure during a 4-mile pack-in at 10,000 feet, where a dropped device in talus is gone for good. The 20-denier polyester backer adds just enough structure for easy layering without turning the jacket into a stiff board. Every detail on this trail-ready piece exists because it was field-tested in the kind of conditions where gear either works or it doesn't — there's no middle ground at 11 degrees with windchill on day eight of a backcountry hunt.

Layering Compatibility

Built to slip comfortably under your hunting shell without restricting movement or your shot.

  • Accommodates a mid-weight base layer beneath without binding
  • Fits under standard hunting shell jackets with full range of motion

“Wore this under my shell for eight days in the Bob Marshall. Rained four of them straight. Never once felt like I was losing heat, and at 16 oz I forgot it was there until I needed it. This is the layering piece I should have bought years ago instead of messing around with down that clumped the first afternoon.”

Frequently Asked Questions

Down clumps and loses insulation value the moment it absorbs moisture — which happens fast in rain, sweat, or snow on a backcountry hunt. PrimaLoft® Gold with Cross Core™ technology retains warmth when wet, maintaining thermal performance through the conditions that shut down down-filled jackets. For a hunter who can't control the weather but can control his layering system, synthetic is the more reliable choice.
The Kelvin AeroLite is designed as a mid-layer, not a standalone cold-weather jacket. Under a hard shell in moderate conditions, it performs well on its own. For sub-freezing backcountry hunts, it excels as part of a layered system — base layer, AeroLite, and shell. The warmth-to-weight ratio at 16 oz makes it ideal for the active portions of a hunt where you're generating body heat but still need insulation during stops.
Hunt Premium is an authorized dealer on every brand we carry. Your Kelvin AeroLite Jacket ships with full manufacturer warranty support — no gray-market risk, no voided coverage if something goes wrong. We confirm authorized dealer status because at this level of gear, warranty backing matters as much as the product itself. Buy with confidence that your purchase is fully covered.
The Kelvin AeroLite Jacket comes in Subalpine across sizes Medium, Large, Large Tall, XL, XL Tall, and XXL. The Tall options add length in the torso and sleeves for hunters who need extra coverage without sizing up and adding unnecessary bulk around the midsection. If you're between sizes or unsure about fit for your layering system, reach out — we'll walk through it.
Silica aerogel is composed of more than 95% air, making it one of the lightest insulating materials available. In the Kelvin AeroLite, aerogel particles are infused into the PrimaLoft® Gold synthetic fibers, adding thermal resistance without measurable weight. The result is a jacket that traps heat more efficiently per ounce than insulation without aerogel — meaningful when every ounce in your pack counts on a multi-day backcountry hunt.
Hunt Premium offers a 30-day return window. If the jacket doesn't fit your layering system, return it unworn in original packaging with tags attached for a full refund. The goal is for you to try it under your shell at home and confirm the fit before committing to the field. We'd rather you send it back than carry gear that doesn't earn its spot.
