Mountain Hardwear Flow Factor Down 2027 – Insulated Jacket

The Flow Factor Down is Mountain Hardwear's answer for experienced resort riders who want the warmth of a serious down jacket without the bulk or noise of traditional insulated outerwear. Designed for lift-served terrain and long days on the hill, it pairs genuine insulating performance with a refined, low-profile silhouette.

At its core, 650-fill RDS-certified down delivers dependable warmth across a range of conditions, all wrapped in a two-layer ripstop nylon shell that resists wind and weather while staying remarkably light and supple in motion. A reinforced overlay on the shoulders and arms adds durability where you need it most, and the relaxed fit — roomier through the body with a longer cut — gives you the range of motion to ride all day without feeling restricted. The helmet-compatible hood adjusts three ways, underarm vents help manage heat on the uphill or warmer days, and an integrated RECCO reflector is there as a quiet safety net when your line takes you beyond the groomed.

This jacket suits the rider who splits time between groomers and side-country excursions — someone who values warmth without sacrificing packability or style. If you run hot, the venting system keeps things manageable; if you push into untracked terrain, the RECCO reflector and pass pocket mean you're covered on both convenience and safety.

• Is the down fill ethically sourced? Yes — the insulation carries RDS (Responsible Down Standard) certification, verified independently through Control Union (License CU 848416).
