The Jackaloft is super low profile, incredibly warm, and highly packable. Designed for layering under an outer jacket and armor on the bike, but works just as well around camp or in town.

Jackaloft Insulated Jacket

Introducing the redesigned staff favorite Jackaloft Jacket. We started with the same exceptional insulation and focused on improving both mobility and weather protection. By utilizing a stretch 20D ripstop fabric, along with a refined fit, we delivered improved freedom of movement, while a dry microporous fabric and DWR coating provide additional protection against light weather and precipitation.

In addition to the upgrades, the Jackaloft remains true to itself; a super low profile, exceptionally warm, and highly packable insulation layer that's cleverly disguised in a classic overshirt design. Casually styled to integrate between riding, travel, and town, the Jackaloft is as versatile as it is functional.

DESIGN

Don’t let its humble silhouette fool you. The Jackaloft insulated shirt-jack punches way above its weight. Ultralight, highly compressible, and super warm, the Jackaloft uses fully synthetic PrimaLoft® Gold insulation with Cross Core technology. This high-tech insulation combines PrimaLoft's top-of-the-line fibers with aerogel (google ‘aerogel’ for more info!) to provide 52% more warmth than the same weight of PrimaLoft® Gold alone. This enhances warmth and decreases weight, resulting in a highly packable, ultralight garment.

Originally developed by NASA, aerogel is composed of more than 95% air and is the lightest solid material known to man. It’s also one of the most effective insulation materials ever made. When integrated directly into synthetic fibers, aerogel dramatically enhances warming. This isn’t just something you see in charts and stats. You’ll immediately feel the effects yourself when you wear the Jackaloft. On a moderately cool evening, you might be surprised to find yourself leaving the Jackaloft partially unzipped, which is surprising given its size and weight. We packed as much warmth as we possibly could into this very small package.

The size of the Jackaloft is important not only on warm days when it’s packed away on the bike but also on cold days when you’re wearing it under armor. With insulation, body armor, and an outer shell, one of our biggest challenges is how to layer up without making our riding kits so bulky that we can’t move around. Another challenge is that body armor, a shell, and constant wind pressure on a non-windscreened enduro bike can compress your insulating layer, removing its loft and reducing warmth. That’s why the Jackaloft uses synthetic insulation rather than goose-down. Synthetic fibers will maintain their loft even under pressure, keeping you warmer on the bike.

We styled the Jackaloft as a shirt-jack for a very practical reason: we want this to be the only insulating layer you need on your trip. If we can disguise a highly technical insulated riding layer as a badass garment that you’re stoked to wear around camp or on your next Tinder date, then that’s one less thing you have to pack. Wear it everywhere.

Looks to thin

I returned the jacket (orange). It is very light and thin. Almost a see-through jacket. I had my doubts if it would be warm enough. That is why I returned it.

Hi Rob, we’re sorry to hear that the Jackaloft Insulated Jacket didn’t meet your expectations. The Jackaloft is designed to be a lightweight, packable mid-layer that balances breathability with warmth. While it might feel thin, its synthetic insulation is engineered to provide effective warmth in cooler conditions without adding bulk.

If you’re looking for a heavier, more insulated option for extreme cold, we'd recommend our Ectotherm Insulated 12V Heated Jacket. If you'd like any assistance finding a jacket, don’t hesitate to reach out to our customer service team. We're here to help!

Jackaloft Insulated Jacket

My purchase of the year. Was wearing it and a tee shirt whilst others around me had 3 heavy layers of clothing on and were still cold. Coming from just living in the Tropics to The Colder climates of Australia 🦘🌏🦘 I really feel the cold, but not that night. Is my go to jacket 🧥 now and my mates were amazed at how light construction it is and how it packs away. Well worth the money. Awesome job Mosko Moto.

Excellente sous-couche.

Ce manteau est une excellente sous-couche, qui plus est toute en style. Elle est super compressible, isole très bien du froid. Je l'ai porté avec un manteau mesh à 8 degrés.
Je mesure 1,83m et j'ai pris une taille L, qui est parfaite.

Great quality, great fit.

Not the warmest jacket on its own, but sufficient with layering as described. Not a huge fan of the logo at the top of the main zipper lining - really screams "see the logo". But otherwise would definitely recommend it.
