A lightweight quilted jacket that brings targeted warmth without ever restricting movement under a backpack.

The Stormtech Nautilus QXH-1W is a quilted hooded jacket for women, built for outdoor activity in cold weather. Its outer shell in 100% pongee polyester, 90gsm, blocks the wind and carries a DWR water repellent finish that sheds dry snow and short showers. The ultra-lightweight thermal lining warms without adding bulk, leaving the freedom of movement needed on the move. Comfort from +5°C to -10°C*, from XS to 3XL. A jacket worn alone on a winter hike, becoming a 2nd layer under a waterproof jacket once altitude or weather demand it.
A jacket is judged at the pause, when the body stops producing heat and the wind takes over. The adjustable thermal hood closes with one hand without putting the pack down, and the quilting holds its warmth under the shoulder straps. Plan for a breathable base layer underneath for the climbs.
Outdoors, heat is lost first through wind and openings, rarely through the fabric itself. The thermal quilting retains warm air against the body, the 100% windproof outer shell keeps it from being swept away, and the full-length internal storm flap doubles the closure up to the chin. The elasticated cuffs hold firm against poles and gloves alike, and the adjustable hem cinches down before a break. Two limits should be clear: this model is water repellent, not waterproof — it handles dry snow and short showers but not sustained rain at altitude. And below -10°C, it moves to a mid-layer role under a suitable outer jacket.
Because outdoors, the right garment is the one that serves in two configurations instead of one. Alone, the Nautilus QXH-1W covers winter hiking and static stakeouts down to -10°C* thanks to its 100% windproof outer shell. Under a waterproof jacket, its thin quilting adds insulation without creating the bulk that gets in the way at the shoulders. One jacket, two roles, a lighter pack.
The Grand-Froid three-layer system: a breathable thermal base layer moves moisture away from the skin ; an insulating second layer, here the Nautilus QXH-1W, traps body heat ; a third layer protects against wind and water. This model sits in the second position while also covering part of the third thanks to its windproof fabric, which is why it holds up alone down to -10°C. Below that, or under sustained rain, add a waterproof outer jacket on top.
* Indicative thermal comfort from +5°C to -10°C. Perceived warmth depends on activity level, wind, humidity, body type and the layering system worn underneath.
