Fantom
£179.99 £229.99
Striking the perfect balance between warmth, weight, and compressibility, the Fantom is the only serious down jacket you’ll ever need.
- Large baffles of ethically sourced 650 FP hydrophobic duck down for maximum insulation
- Compressible materials and a lightweight construction
- Adjustable helmet-compatible hood and a two-way zip
- 100% recycled nylon fabric and PFC Free DWR
The Fantom is designed to keep you wonderfully warm, from the highest of Alpine Peaks right down to chilly valley camps around the tent. We’ve used large baffles packed with 650 fill power RDS-approved ethically sourced down. There’s a whole lotta loft inside those baffles – enough to keep you seriously snug at subzero.
By using lightweight, 100% recycled nylon ripstop, a stitch-through baffle construction, and simplified features, we’ve managed to keep the overall jacket weight low for its warmth. This also makes the Fantom highly compressible for stuffing away in rucksacks.
For climbing and mountaineering use, there’s a helmet-compatible hood with wired peak and a two-way front zip. The longer cut also stops your bum from getting chilly on long belays! The hood can be cinched right down with side and rear adjustors so that it keeps out draughts and follows your head movements.
DownTek™ PFC-free hydrophobic down adds extra moisture resistance – it loses less of its insulating loft when wet, dries quicker and is less prone to clumping. The outer shell is also treated with an environmentally friendly PFC-free water repellent to brush off light snow and drizzle.
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.
