The Pyro Down jacket from Crux gives you exceptional warmth for its weight thanks to 180g of the best quality down money can buy housed in a box wall construction.

Crux says:

We will be bold here and say it outright: for its weight, the Pyro is by far the warmest jacket you will find anywhere. The secret to its warmth lies not so much in the amount of down it contains, which actually is not a lot (180 g of 850 cu.in. (EU) Polish goose down), but due to the fact that – uniquely for such a lightweight jacket – the Pyro features a box-wall baffle construction. This makes the Pyro considerably warmer than jackets with far more down but still featuring stitch-through baffles that leak heat like a colander drains water. Of course there is one downside – jackets with a box-wall construction take much longer to sew and this this is reflected in their higher cost. The benefit, however, is that you have a lighter, more compact and more thermally efficient jacket.

We have modified the Pyro jacket for 2019. The chest pocket is now on the inside, and the hood as been upgraded to fit over climbing helmets.

Crux's Pyro Down Jacket is built around providing maximum warmth for the minimum of weight. 915+ fill power is amongst the best quality down possible and is responsibly sourced. The Crux Halo jacket has slightly better quality down but the Pyro has box wall construction making it even warmer as it eliminates the cold spots of sewn baffles.

The box wall construction and exceptionally high quality down are the key ingredients of this lightweight insulation piece. The water resistant outer is quite tough at 20 denier. The wired peak hood is helmet compatible and can be adjusted in size with 2 draw cords around the neck. The wrists have velcro adjustment and there is a drawcord in the hem.

The Pyro has 2 zipped handwarmer pockets a with a further chest pocket. A stuff sac is included. A decent sized internal down baffle prevents heat loss through the zip.
