Men's Lakeside Trip Jacket is a windproof and mosquito proof jacket with UV protection from Jack Wolfskin that provides reliable protection from the sun - and from insect bites too. The fabric is a blend of organic cotton and polyester. It has a very tight weave that makes it impossible for mosquitos to bite through and blocks the sun's harmful rays while remaining very breathable. If the weather suddenly takes a turn for the worse, there's no need to worry. The LAKESIDE TRIP JACKET will protect you from the wind and light showers. With eight pockets in total, there's plenty of room for all your important bits and pieces. And there's a handy D-ring under one of the chest pockets to clip your keys to.\n\nFUNCTION 65 ANTI-MOSQUITO UV: mosquito proof, windproof and water repellent, extra breathable hybrid fabric with certified organic cotton and UV protection UPF 40+D-ring on chest pocketadjustable hem
