Jackaloft Insulated Jacket

Jackaloft Insulated Jacket


Jack's back! Introducing the redesigned Jackaloft Insulated 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 superior 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 seamlessly integrate between riding, travel, and town, the Jackaloft is as versatile as it is functional.


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.

Jackaloft Insulated Jacket

Jackaloft Insulated Jacket !
Very very good quality !
Very happy with this product!


When you Jackaloft... you'll get a natural high that feels better than... well, you know. I could tell that Ash and Jack were trying very hard not to laugh during the video promo. Whoever came up with that name certainly didn't think about the marketing consequences.😁

Comfy & warm & stylish

Very good as 3 season insulated layer. Design wise, the armpit is larger than Surveyor one. Highly usable as day by day jacket as well.

Best jacket ever

You nailed it guys. This is the best insulated jacket I’ve ever seen. The fit is spot on and it looks like it was custom made by an Italian tailor.
I’m in Argentina and we are now in summer but I can’t wait to test it in the mountains.
Kudos and keep it up.
