Sun Mountain's Cirque II Rain Jacket Rated to 20K Waterproof

Sun Mountain's top-of-the-line rain jacket, the Cirque II, is built with a 20,000-millimeter waterproof rating and a 30K breathability rating, placing it above the brand's value-oriented Monsoon jacket in its outerwear lineup.

What protection does the Cirque II offer?

The jacket uses seam-sealed waterproof and windproof construction, with waterproof zippers sealing its openings against moisture. The 20K figure refers to the amount of water pressure, in millimeters, the fabric can withstand before leaking, while the 30K rating measures how quickly built-up heat and sweat can escape through the material, a factor in keeping a golfer from overheating mid-round.

What design features does it include?

The Cirque II has adjustable cuffs and hem, an internal hidden chest pocket, and reflective logo accents. It comes in three colorways: Dark Feldspar, black and navy. The outer shell avoids the stiff, plastic-like feel common in rain jacket fabrics, though it can produce a rustling sound during a swing.

The jacket has been well received for balancing its waterproofing with breathability, avoiding the overheating that can come with heavier rain shells. It is positioned as the step-up option from Sun Mountain's Monsoon jacket, which the brand sells as its more budget-friendly wet-weather shell.
