When the sun's blazing and the trail calls, the Smartwool Merino Sun Hoodie delivers the perfect balance of protection and performance for your outdoor adventures. This lightweight merino wool hoodie combines Smartwool's signature comfort with serious UPF 40+ sun protection, making it your go-to layer for hiking, paddling, or any sunny day exploration. The innovative dual-layer construction keeps 100% merino wool against your skin for natural odor resistance and moisture management, while a recycled nylon core adds durability without the bulk. The large hood provides comprehensive coverage for your head and neck, while thumbhole cuffs extend protection to your hands and keep sleeves in place when you're on the move. With its relaxed fit and offset seams designed to minimize chafing, this men's sun protection hoodie lets you focus on the adventure ahead, not on adjusting your gear.
