A little while ago Endura released their latest winter jacket, the ultra-portable Pakajak, which offers an emergency windproof shell that packs down into its own stuff sack.

As a concept, it’s nothing entirely new. But Endura clothing always ticks a box with UK mountain bikers; combining as they do well designed apparel and good prices. Being based up in Scotland gives them the ideal conditions to thoroughly test their clothing

The fact the Pakajak costs a mere £39.99 doesn’t do it any harm either. A sample duly arrived on the Bikemagic editorial desk, and here it is. Let’s get the tech stuff out of the way first: it’s made from a lightweight Ripstop fabric, its showerproof and windproof, and features are kept few and far between to keep the weight low.

Before. Fresh out of the box it’s very neatly rolled up. Will it stay this way? Let’s find out.

Removing the small bag that keeps the Pakajak rolled up until it’s needed. First thing to note is how insanely light it is, plus the miniscule size that means it’ll take up no space in even the smallest pocket or backpack.

Unravelling the jacket. It’s very neatly folded up. I’m paying attention to how it’s been folded up in the hope I can repeat the process.

And hey presto, the jacket pops into life like an emergency raft, minus the pull cord (though that would be a cool feature). A bit crinkled, but they’ll soon fade with constant use.

There’s a nice storm flap for the lock-down full-length zipper. The material is very thin between the fingers, the lightest of any jacket we’re currently testing. It feels delicate.

There’s two mesh-lined air flaps on the reverse of the jacket. Should go some way to controlling your temperature.

Couple of reflective details, one on the dropped tail and some around the shoulders.

Remembering my valuable lessons from camping and packing tents away, I carefully fold and roll the Pakajack back into a small parcel, and it effortlessly slips into its dedicated bag.
