Enjoy long hiking weekends in the mountains with this versatile Columbia long sleeve shirt. Its material protects you from the sun's harmful UVA and UVB rays, and works to regulate moisture by quickly absorbing it, keeping it away from your body. The top is ventilated and for an extra feeling of freshness, you can practically roll up the sleeves and lock them. Essentials can be stored in the functional chest pockets. For even more sun protection, there's a collar.
