If you're bored with the gym and prefer to do your daily workout outdoors, even in colder temperatures, the Womens Grid Tights from Jack Wolfskin are a great choice. Ideal for winter workouts on the fitness trail, these leggings consist of a highly functional stretch fleece fabric that provides basic insulation. The fabric has a smooth outer surface and delivers the advanced wicking performance you need when you're training hard and working up a sweat. And the stay-fresh function minimises unpleasant odours. An integrated zipped pocket provides a safe place to stash your keys and cash.
