DESCRIPTION:
The I1 Ruff Jacket is part of the Insulated Series. The formula for snow is one part cold and one part wet, yet these ingredients are no recipe for comfort. So, in zones where bitter cold is the norm, a heater is the best one-shot strategy for staying warm and dry. Foursquare's fortified designs blend puffy down or fixed synthetic fill with storm-proof exteriors to conserve heat even in arctic air. Worn solo over a shirt, they stoke internal temps when making morning laps, sledding into a spot, or stumbling home after dark.
FEATURES:
-25,000mm waterproofing.
-10,000gm breathability.
-Puffy 80/20 goose down insulation.
