"What Our Gearhead® Experts Are Saying:""This is a versatile layering piece that punches way above its weight. It’s super breathable, great for long days in the sun, and perfect for those quick transitions between jobsite, hike, or road trip.""Whether you're pushing through a full day of outdoor work or catching an early trailhead start, the Carhartt Force Sun Defender™ Relaxed 1/2-Zip Shirt offers lightweight performance that doesn’t quit. Built from soft polyester jersey, it wicks sweat, dries fast, and delivers UPF 50+ protection to help shield your skin from harmful rays. Odor-fighting technology keeps things fresh even as temps rise, and a tagless neck and relaxed fit keep it comfortable through movement and layering. This half-zip style is as easy to throw on at sunrise as it is to stash in a pack when the day heats up."
