Boonie-style brimmed hats boast a practical middle-of-the-road brim, placing them between bucket hats and Stetson-style hats. The Rab Boonie Hat provides protection from the suns rays and, when needed, from light rain showers as well. As a fun bit of detail, there are openings at the temples where you can slip in the arms of your sunglasses when you push them up onto your forehead. - Breathable mesh panels - Soft brim: the hat can be packed into a backpack even a bit carelessly and will always return to its shape - Quick-drying fabrics - Elastic adjustment cord helps optimize the fit - Removable chin strap with adjustment buckle Mono-material product: since all parts of the hat are made from polyester, it is easier to recycle at the end of its life cycle than garments made from mixed materials.
