The Vertex is a technical hardshell jacket, fitted with a 3-layer H2XTREME® outer membrane that reaches 20,000mm of waterproofing and 10,000 g/m² of breathability — a level of protection that handles sustained rain without ever letting water through, while still letting sweat escape. The mechanical stretch fabric moves with you without holding you back.
In Quebec, where fine rain can last all day, this is the level of waterproofing that changes everything: an ordinary jacket eventually lets moisture through after a few hours, this one doesn't. The underarm vents let you dump heat during effort, without ever opening the jacket up to the rain.
The manufacturer's classification places the Vertex in the Cold range, up to 5°C / 41°F. The 3-layer H2XTREME® membrane fully blocks rain and wind while letting sweat escape ; the underarm waterproof zips let you adjust ventilation during effort. This jacket carries no insulation of its own: it protects against water and wind, not against dry cold — pair it with a fleece or thermal jacket underneath for colder temperatures.
A technical, waterproof jacket, built as the third layer for sustained rain.
