Men’s medium but I wear women’s 8 and this fits well. Chest and waist are 40”. The Patagonia Houdini Jacket is ideal for when you need a packable, weather-resistant jacket for overcast days. The jacket's windproof fabric is also water-resistant, protecting you from wind and light rain. An adjustable cinch at the hood and on the lower hemline provides a customized fit. The back features a slightly dropped hem for a no-gap fit. When the sun comes out, the jacket can be stored in the chest pocket, so you can stow it away if the weather improves. • Windproof and water-resistant • Packable into chest zipper pocket • Adjustable cinch cord in hood and hemline • Durable half-elastic wrist cuffs • Reflective logo on chest • Slim fit w/ drop tail hem • One zippered chest pocket Fabric: • Shell: 100% recycled nylon • PFC-Free DWR fabric finish • Overlock seam construction Questions?
