Alpine Down
New Pyro Jacket
£385
Including UK VAT.
We will be bold here and say it outright: for its weight, the Pyro is the warmest jacket you will find anywhere. The secret to its warmth lies not so much in the amount of down it contains, which is only 180 g of 850 cu.in. 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 using stitch-through baffles that leak heat like a colander drains water.
The cut is generous in length and the adjustable hood design fits comfortably over most climbing helmets. The two hand-warmer pockets are complemented by an internal chest pocket.

Care & attention+
Down is a very resilient insulating material and, with basic care, any down jacket should last you a very long time.
There are two simple rules to ensure longevity:
1. Always store your jacket uncompressed in a dry, airy place
2. Try to keep it as clean as possible to minimize washing (this ultimately damages the down).
We highly recommend you hand-wash your down garment or, alternatively, use a professional service. You can download washing instructions here.
