The Patagonia Men's Houdini Jacket is an ultra-light and protective layer, ideal for bringing along on your trail runs in unpredictable weather. Sustainably made windproof fabric and a safe, water-resistant DWR finish will shield you from the elements. An adjustable cinch at the hood and on the lower hemline provides a customized fit, and a slightly dropped hem supports movement for a no-gap fit. The whole jacket packs into the chest pocket, so you can easily stow it away if the weather improves.
