Winter jacket design often comes down to a trade-off between protection and breathability—add enough insulation and windproofing to handle genuinely cold conditions, and you risk turning every climb into a sauna. Assos built the Mille GT Hashoogi Winter Jacket S11 around their three-layer Triassembly construction specifically to navigate this problem, using different materials in different zones based on how your body actually behaves during winter efforts.
The front panels use RX Heavy fabric that blocks wind while the back switches to RX EVO material that manages moisture escape during high-output efforts. The sleeves get their own treatment with RX Heavy fabric positioned where wind exposure hits hardest. This zoned approach means the jacket works across a wider temperature range than single-material designs typically manage—Assos rates it for 29°F to 46°F, which covers everything from proper cold snaps to those damp shoulder-season mornings that can't decide what they want to be.
The Hashoogi name references the oversized hood, which is the jacket's most distinctive feature and likely its most polarizing. This isn't a fitted hood that tucks under your helmet—it's a substantial piece that sits over your helmet when deployed, covering your ears and the back of your neck while leaving your face clear. When conditions warm up or you simply don't need it, the hood stows into a collar roll that sits at the nape of your neck. The design choice prioritizes protection over minimalism, which will appeal to riders who've learned the hard way how much heat escapes through an exposed head during long winter descents....

Construction details include a full-length front zipper with an interior wind flap, three rear pockets for standard storage, and reflective accents for low-light visibility. The cuffs use a stretchy binding that seals against your gloves without requiring excessive grip that would complicate mid-ride adjustments. The hem sits longer in the rear to maintain coverage in the riding position.
The jacket runs in Assos's standard sizing and uses their regularFit pattern, which provides enough room for a base layer and mid layer underneath without the excess material that would flap in the wind. The two colorways—Blackseries and Dune Sand—give you a choice between traditional understated and something that shows up a bit better in flat winter light.
