Fantom
$209.99 $329.99
The Fantom strikes the balance between warmth, weight, and compressibility, it’s the only serious down jacket you’ll ever need.
We’ve used large baffles packed with wonderfully warm 650 fill power duck down from RDS-approved suppliers. There’s a ‘lorra’ loft inside those baffles: enough to keep you snug at subzero and on the highest of Alpine peaks. That might be a lot of fill but we’ve used a superlight and tough 20 denier ripstop nylon fabric and a stitch-through construction, reducing the overall weight and keeping the jacket compressible for stuffing away in rucksacks.
A helmet-compatible hood with wired peak and a two-way front zip accommodate the needs of climbers, and a longer cut stops your bum from getting chilly on long belays. As well as hem pull-cords, the hood can be cinched right down with side and rear adjusters, keeping out draughts and mimicking your head movements. Hidden elastic cuffs are neat under or over gloves.
The zipped handwarmer pockets and collar have a soft tricot lining so you can really hunker down and stay cosy when the cold bites. There’s an internal zipped chest pocket - useful for keeping phone and headtorch batteries warm – and two internal dump pockets too, for defrosting gloves or warming up climbing shoes during grit season.
Downtek™ PFC-free hydrophobic down adds extra moisture resistance: losing less of its insulating loft when wet, drying quicker and is less prone to clumping. The outer shell is also treated with a PFC-free C0 Durable Water Repellent to keep the drizzle at bay.
