The Desert Hat from Lowe Alpine is a simple & comfortable bucket hat made form their superb Desert Weave nylon fabric that breathes, dries quickly & has a UPF 50. A full neck flap is stowed in the rear zipped compartment & can be quickly deployed to protect you from those harmful UV rays. Lowe have also used their Dryflo (base layer) fabric on the internal headband to wick away sweat & provide a softer contact area. This versatile & lightweight hat is a must for anyone, who like me, burns at the slightest suggestion of sunshine. Ultra violet Protection Factor (UPF) 50 Back zipper stows neck flap Full brim protects from sun glare Dryflo headband for fast wicking of sweat
