Most hunters don’t think about their jacket until they’re standing in 30-degree wind with an hour of shooting light left and a buck working through the timber. By then it’s too late to fix. The right jacket isn’t just about staying warm—it’s about staying still longer, staying quiet when it counts, and staying focused when a mature buck is inside 20 yards.

ASIO builds jackets specifically for whitetail bowhunters. For whitetail bowhunters who sit in trees for hours, draw bows in tight spaces, and obsess over the smallest details. Here’s a breakdown of the three jackets in the 2026 lineup and how to pick the right one for your hunt.

ASIO Midweight Puffy Jacket in Raptor Camo

Midweight Puffy Jacket — $229 →

80g PrimaLoft® Gold insulation in a reversible camo-to-black design. One of the quietest puffies on the market.

ASIO Midweight Sherpa Jacket in Raptor Camo

Midweight Sherpa Jacket — $269 →

Windproof membrane with sherpa fleece interior. The outer layer most ASIO hunters reach for from October through the rut.

ASIO Heavyweight Hooded Jacket in Raptor Camo

Heavyweight Hooded Jacket — $379 →

180g PrimaLoft® Gold with a built-in hood. For the guys pushing into sub-20 temps and sticking it out on late-season food sources.

Midweight Puffy Jacket — Not Your Traditional Puffy

Most puffies are noisy. They crinkle when you move, rustle against your bow arm, and announce every shift in the stand. The Midweight Puffy Jacket is built differently. Quieter materials, tighter construction—and most hunters who’ve used both will tell you it’s the quietest puffy they’ve ever worn.

The insulation is 80g PrimaLoft® Gold—lightweight, moisture-resistant warmth that doesn’t bulk up your draw or crunch in the cold. The reversible design gives you Raptor or RapX Camo on one side and solid black on the other. That black side isn’t just for the drive home—it’s what box blind and ground blind hunters actually need. No camo required, full concealment in a closed setup.

Good for October cold fronts, mid-season transitions, and those mornings where you’re not sure how cold it’s actually going to get. Available in Raptor Camo and RAPX Camo.

Midweight Sherpa Jacket — The Workhorse

Ask serious whitetail bowhunters what outer layer they reach for most and the Sherpa Jacket shows up on nearly every list. Not because it’s the warmest thing in the lineup—because it gets used constantly. Cold mornings in October, slow evenings in November, rut sits in the wind, and every temperature swing between tolerable and miserable.

The windproof membrane stops the wind chill that actually kills your sit. The sherpa fleece interior is soft and quiet against your base layer—which matters when you’re locked in for hours without moving. Two angled chest zips give you fast access to your rangefinder, calls, or whatever you need without blowing your setup. And the extended tail keeps the jacket from riding up in the stand—trapping heat at the waist, sealing out wind at the gap, and protecting you from a wet seat on those early morning sits.

If you only buy one outer layer for whitetail season, this is it. Available in both Raptor Camo and RAPX Camo.

Heavyweight Hooded Jacket — The Late-Season Answer

The Heavyweight Hooded Jacket is for the guys who are still out there when everyone else has gone home. We’re talking sub-20 degree temps, well into single digits—the kind of cold that hits late December when bucks finally stop moving early and lock into late-season food sources. Cut corn, standing beans, picked grain fields. That’s when the best sits of the year happen, and this jacket is what makes them possible.

The 180g PrimaLoft® Gold insulation is the highest fill weight in the ASIO lineup—maximum warmth without the stiff, bulky feel of traditional cold-weather gear. Wind-blocking protection covers your core. The removable hood covers everything else. The cut is still designed for bowhunter mobility, so you’re not sacrificing your draw to stay warm.

If you wrap your season up before the brutal winter weather kicks in, you probably won’t need this one. But if you’re the hunter who sticks it out until the end, this is the jacket that makes that possible. Available in both Raptor Camo and RAPX Camo.

Which One Should You Buy?

Buy the Puffy if you want one quiet, packable layer that works across a wide range of conditions—or if you hunt from a box blind and need the solid black side. Buy the Sherpa if you want the single go-to outer layer that covers most of whitetail season and handles wind like a champ. Buy the Heavyweight Hooded if you’re hunting when it’s brutally cold and bucks are moving to late season food. The Puffy also layers cleanly under the Sherpa when temps drop lower than expected—giving you a stacked system for the worst days without going straight to the Heavyweight.

“The hunters who consistently kill mature bucks aren’t just better at reading deer—they’re more comfortable sitting longer. Gear plays a bigger role in that than most people want to admit.”

Frequently Asked Questions

What’s the difference between the Sherpa and the Puffy?

Different tools for different conditions. The Puffy is lighter, quieter, and packable—good for milder temps and layering. The Sherpa is a windproof outer shell with a sherpa fleece interior designed to be your primary jacket for most of the season. Most guys end up owning both.

Can I layer the Puffy under another jacket?

Yes—and it works great under the Sherpa when temps drop lower than expected. It’s not typically used under the Heavyweight since that jacket is already built for the most extreme cold. Think of the Puffy-plus-Sherpa combo as your mid-season two-jacket system when you need more than one layer but don’t need to go full late season.

What insulation does the Heavyweight Hooded Jacket use?

180g PrimaLoft® Gold—the highest fill weight in the ASIO lineup. It’s a premium synthetic insulation that stays warm when wet, doesn’t lose loft over time, and performs without the crunch and stiffness of down in cold temps. That fill weight is what makes this jacket viable for all-day sits in genuinely brutal conditions.

What camo options are available?

All three jackets come in Raptor Camo and RAPX Camo. RAPX is a more open, high-contrast pattern that performs well in open timber and bare canopy—exactly the conditions you’re hunting in late season.

Is the Puffy worth it if I already have the Sherpa?

Yes, for a few reasons. First, it’s quieter than most puffies you’ve tried. Second, the solid black side is genuinely useful for box blind and ground blind setups. Third, it layers cleanly under the Sherpa for those transition sits where the Sherpa alone isn’t quite enough. Most guys who pick one up end up reaching for it more than they expected.
