Launched in 2009 — and substantially updated for 2010 — the JakPak doubles as an outer shell jacket and a bivy sack/tent you can sleep in. Worn as a jacket, the detachable tent/sleeping bag combo folds out of the shell’s back panel, making it one of the most unusual and unlikely hybrid products in the industry. (The first time we saw mention of the JakPak we weren’t sure if it was real!)

Active Engineering LLC touts its primary product as an all-in-one system that could replace the need for a jacket and a bivy system. It is made for backcountry types who want to always have a bivy/shelter at hand, but don’t want to have to think about toting along a backpack with that gear. Or something like that, anyway.


The JakPak in bivy/tent mode

For 2010, the JakPak, which is made of a waterproof/breathable fabric, adds pit zips, a no-see-um bug net, and a more “athletic” fit. While the weight of the updated jacket isn’t available, the first rendition weighed between 2.5lbs and 3.5lbs, depending on size.

The updated JakPak will be available in March for $250. www.jakpak.com

Interesting idea… but also kinda strange. And for $250 I think I’d choose another option. Maybe a regular bivy tent that’s ultra light and compact. It’s one of those things… a jacket is good alone… a bivy tent is good alone… combine them and it’s subtraction by addition. :D Still, curious to see if anyone buys and uses the thing.

I’m glad EDC reviewed this. $250 is pretty steep. If you were in a life threatening situation, by the time you fumbled getting this out, you’d be at risk of exposure anyway. There are better and safer alternatives. I’d like EDC to provide mor info on the manufacturer too. Isn’t Active Engineering an electrician firm? Do they have a proven record in safety with outdoor gear? Hmm.

Did some more checking. This actually looks safer than I gave it credit, and is cheaper than the Nemo products.

I looked at the Jackpack at the OR show. It appeared to be cheaply constructed and not adequate for storm situations. The mesh still exposes the occupant to the elements. The so-called sleeping bag is nothing more than a stuff sack. The top of the sack has 5000mm water resistance and the bottom is at 10,000. You would sweat you butt off and them freeze. I would not use this in a camping situation.

the price is unreasonable there are thousands of tents even 2 second tents for less!

$250 way too much. You can buy a much better and lighter bivey sack for $150. This product looks like it was made by the manufacturers of the “in the egg scrambler” and the “pocket fisherman”. This is a bad answer to a question that hasn’t been asked.

Check out the “Bivanorak”, from Hilleberg The Tentmaker
$185 at MoonTrail – and available elsewhere!
It’s a MUCH better Jacket/Shelter Combo, IMHO!

ps – What happened to JakPak’s BRIGHT Yellow version? Meh…
