The Nuptse has been around since 1992, and somewhere along the way it split into two identities: a genuine mountaineering tool and a street-style staple spotted everywhere from Melbourne cafes to Kensington High Street. The new Summit Series version is The North Face dragging the icon back to the mountains, and Australian Geographic's reviewer recently put one through its paces on a packrafting trip down the Snowy River — arguably overqualified cover duty, but a decent shakedown nonetheless.

The spec sheet reads like a serious alpine jacket, because it is one. The fill is 800-fill ProDown, a water-repellent goose down certified to the Responsible Down Standard, arranged in offset baffles (Cloud Down construction) to cut cold spots and pack smaller. The shell is 15-denier recycled nylon ripstop with tougher Spectra fibre reinforcement across the shoulders, collar and hood — areas that usually cop the abuse from pack straps. Recycled materials run throughout, including the synthetic-insulated draft flap, and there's a non-PFC DWR finish for light moisture. Claimed weight: 554 grams.

In the field, the verdict was warm — emphatically so. This is a stop-and-puff jacket, not something you'd wear uphill with a heavy pack. It lofts up to near-parka bulk when you pull it from its stuff sack, so packed size is substantial even if the weight is reasonable. The shorter, boxier cut raised concerns about a cold lower back but won the reviewer over: it sits cleanly above a climbing harness or hip belt and sealed out drafts as well as longer jackets. Clever touches impressed most — a helmet-compatible hood that zips away into the collar, glove-friendly squared zip pulls, stretch cuffs instead of Velcro, a hem adjuster hidden inside the hand pockets, and two huge internal mesh pockets that swallow gloves, a beanie or a one-litre bottle.

A few honest caveats. Water-resistant down is not waterproof — soak it and you're in for a bad time, so keep a shell handy. The stuff sack is separate and detachable, which the reviewer found annoying and easy to lose. And then there's the price: at $1,100 Australian, it's a serious investment, though the reviewer's long experience with The North Face's ProDown and the same construction in the Pumori parka lent real confidence in the build.

Who's it for? Backcountry skiers, climbers and alpine trekkers who want a genuine belay jacket that doubles as a very good-looking everyday puffer — and who can stomach the price. Casual travellers who just want a warm layer for city winters can spend far less elsewhere. But if you're standing around a frozen campsite watching the temperature drop, this is the jacket you'll be smug about having packed.

A well-made, thoughtfully detailed alpine down jacket that gets almost everything right — as long as your budget survives the hit.
