The Cirque, Sun Mountain’s top peak rain collection, is extremely lightweight, waterproof, quiet and breathable due to its three-layer construction. The waterproof/breathable membrane has a 20K waterproof rating and an elite 50K breathability rating. The bonus is the level of 4-way stretch in this fabric. Rarely with ratings like this will you have a piece that combines all the attributes of the Cirque: featherlight, waterproof, breathable, 4-way stretch, quiet, windproof and ultimately, playability. Since Sun Mountain introduced RainFlex in 2006, the company has prided itself on providing the most playable rainwear on the market. Cirque is setting the new bar. Two-year waterproof guarantee.
