Simply put: The Seattle Sombrero is one of the greatest celebrations of Outdoor Research's legacy in trusted outdoor protection since the 80's. And now they’ve come up with an even lighter version perfect for rides when no rain is expected. The Seattle Sun Sombrero is built with the same water-resistant durable 70D brim – sans a liner or Gortex insert. The internal adjustable cinch-band keeps headwear in place, UPF 50+ protection guards against harmful sun rays, and a packable design weighing in at a mere 3.2 oz ensures the fondly-known Sea Sun Som stays put at the top of your packing list.
