Nano Jacket


When we launched the Halo top in 2007, it was the lightest down garment available at the time. But even back then, our end-use trials showed us there was scope for products with even less down fill. The equation goes like this: take your likely personal energy output while wearing a down jacket (e.g. hiking/skiing/climbing), factor in the outside temperature, and then work out how warm (or not) your jacket needs to be. We came to the conclusion that a single jacket was never going to suit all the permutations, so we introduced the Nano jacket and Pico top.

The Nano jacket is our lightest full-zip design. Its low fill weight is offset by the use of the finest Polish down available (a whopping 970 cu. in.; but actually we use this quality throughout all our styles anyway, so it shouldn’t be a surprise). We still insist on using a tough 15 denier Pertex® fabric, though. The Nano is not a pure insulation piece – it hasn’t really got enough down fill for that. But if the mercury is in the twenties (sub-zero Celsius) and you’re in low-intensity workout mode, then the Nano will maintain the equilibrium. Roughly speaking of course – we all have different interpretations of “low-intensity”!

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.

Delivery & Returns

All our products are shipped with UPS for quick, reliable and secure delivery. As most of our products are quite large and/or of high value, they will require a signature. We cannot deliver to P.O. boxes.

All orders are dispatched the next working day after receipt (Monday to Friday). As we are currently searching for new premises in the US, all orders are being dispatched from the UK parent company so typical delivery time is 3-4 days.

If you are not satisfied with your purchase, you can return it for an exchange or refund provided it is within 90 days of receipt of your order and the item is in the original packaging. Please email carol [at] for instructions.
