It's a tale as old as time--you head out for a run thinking you'll still be able to beat the heat even though you're running with a T-shirt on, but after only a mile or two you realize you've made a huge mistake. Now your options are either to deal with the discomfort for the rest of your run, take off your shirt and run with it in your hand, or hide it behind the most inconspicuous tree you can find. Well luckily for you, Nike's always thinking of ways to make your runs easier, and they've got your back with the Tech Pack BF 5in Shorts. In addition to their stretchy mesh fabric, supportive inner lining, and airy split-leg design, these shorts feature a tunnel-shaped mesh pocket in the back that lets you store your running tee when things get a bit too hot on the road or trail. This low-profile pocket makes hot weather T-shirt dilemmas a thing of the past, so you'll no longer have to pretend you wore your workout top as a bandanna on purpose.
