Our Verdict
A versatile, put-on-and-leave-on synthetic layer built for year-round movement in cool, variable conditions.
At 368 g (Medium), the Vesper Insulated Jacket offers an ideal mix of warmth, breathability and mobility. Using VerticalX Eco SR insulation and a stretch nylon shell, it feels light and supple, moving easily during climbs or long hikes without restriction. The fit is trim yet comfortable, working well over a base layer or beneath a shell when the temperature drops.
The drawcord hem and elastic cuffs help seal in warmth, while the wind-resistant shell strikes a balance between weather protection and excellent moisture management during steady activity.
Durability is reassuring for such a light piece, with a more robust shell than many minimalist synthetics. The Vesper Jacket excels as a dependable, all-day midlayer that stays comfortable across a wide range of conditions.
