How it compares
When compared to standard bucket hats or wax-cotton rain hats, the Outdoor Research Seattle Sombrero offers superior breathability due to its GORE-TEX membrane. While traditional umbrellas are prone to wind damage, this hat stays secure and leaves your hands free for trekking poles or gear handling. It is significantly more durable than lightweight emergency rain ponchos.
What to know before buying
- Measure your head circumference carefully as the sizing runs slightly large to accommodate a liner underneath.
- Ensure the brim is fully extended before storage to maintain the internal foam structure.
- Clean the hat with a technical wash rather than standard detergent to preserve the DWR finish.
- Use the internal hook-and-loop adjustment to dial in a snug fit before facing high winds.
The Seattle Sombrero has been my constant companion for three seasons of PNW hiking, and it has never leaked a drop.
Sustainability & ethics
Outdoor Research focuses on longevity as a form of sustainability, using bluesign® approved materials to ensure chemical safety. The hat is 100% free of animal products and features a recycled polyester lining in recent 2026 iterations. Packaging is minimized to reduce the carbon footprint during shipping.
Pro tip
Fold the sides of the brim up using the hook-and-loop patches to create a 'Aussie style' look which also helps with ventilation during steep climbs.
Frequently asked questions
