The warmest layer in the collection: Polartec High Loft's tall, airy pile holds more warm air.
Made for the cold stops: camp, belays and summits.

Stretch nylon across the shoulders and upper back, on the forearms and down the lower sides.
It takes the pack straps, hip belt and elbows, so the pile doesn't get crushed or worn down.

Full-length two-way zip.
Open it from the top, the bottom or both, to let heat out or get at the layers underneath.

2 angled zip hand pockets.
Hands in at every stop. Zip them shut and nothing falls out.

Bungee hem with a cord lock.
Cinch it to keep draughts out. Loosen it to vent when you get moving.
Where we've taken it

High Loft
Polartec created synthetic fleece in 1981 and supplied the fleece behind Patagonia's first Synchilla and The North Face's Denali. High Loft is its tall-pile fleece: a taller, airier pile that holds more warm air for its weight than dense fleece.
That’s the US Army’s Gen III cold-weather Level III fleece jacket, nicknamed the “smoking jacket”. High Loft is the fleece in this jacket.
Military facts are about Polartec's fabrics, not our garments, which aren't military issue. Sources: Polartec (Soldier Systems Daily and Textile World, 2019); Defense Media Network (2013). Image is a 3D render.
Why not just a regular fleece jacket?
Its pile is taller and airier than dense fleece, so it holds more warm air for its weight. Wear it on its own on dry, still days, or under a shell in real cold. Drag the line to see the difference.
