Swift Bucket Hat
Outdoor Research
The Outdoor Research Swift Bucket Hat adapts the wildly popular mesh-venting architecture of OR's Swift Cap into a full 360-degree brim format. If you find standard full-brim hiking hats too broad, unwieldy, or easily pushed around by wind, this bucket profile provides a closer, sportier fit that stays planted while still protecting your ears and face from overhead radiation. The design shines on hot, humid trails where moisture management is the main problem. The crown features an open-sided nylon panel that floats over an airy mesh layer, creating a direct exhaust pathway for sweat vapor. When a breeze kicks up, air flows directly across the top of your head. The fabric is treated with a UPF 50+ rating on the solid panels, and the internal TransActive sweatband does a commendable job pulling moisture off your forehead before it drips into your sunglasses. Because it is a bucket hat, the brim width is intentionally narrower than that of a booney or sombrero style. It provides excellent midday protection when the sun is directly overhead, but in early morning or late afternoon, lower-angle sun will sneak under the brim onto your lower neck and chin. For thick forest hikes, humid river scrambles, and light-and-fast outings, it offers exceptional temperature regulation. **Highlights** - Two-piece crown system with floating nylon panel over breathable mesh - Compact bucket brim resists wind catching and stays planted at speed - UPF 50+ protection on top crown and brim panels - TransActive wicking headband moves sweat away rapidly - Stuffs down into pocket-sized dimensions without brim damage **Watch-outs** - Narrower brim offers less complete coverage against low-angle morning/evening sun - Lacks a rigid chin strap system for severe summit winds

Sombriolet Sun Hat
Outdoor Research
The Outdoor Research Sombriolet Sun Hat is engineered for relentless, unforgiving sun environments like open river corridors, white-water paddles, and desert canyons. If you have ever been frustrated by broad-brim hats that fold in half and slap your face the moment a gust hits you, the Sombriolet solves that problem with a heavily reinforced brim edge. It holds its flat, saucer-like shape in windy conditions that would turn softer hats inside out. The brim is substantial, offering wide shade across the face, cheeks, ears, and neck. Piping around the outer circumference provides structural rigidity, while crown vents are strategically placed to let hot air escape without compromising UPF 50+ protection. The underside of the brim features a dark fabric lining that absorbs reflected glare bouncing off water, limestone, or desert scree. A stout chin cord and a rear crown cinch ensure that the hat stays locked onto your head when running river rapids or cresting windy saddles. That extra brim reinforcement comes with a clear packability trade-off. You cannot roll or crush the Sombriolet into a tight ball without permanently warping the edge piping; it needs to be laid flat in a pack or fastened to the exterior. It is also noticeably heavier on the head than the Helios, making it a dedicated sun tool rather than an ultralight emergency layer. **Highlights** - Reinforced, stiffened brim edge holds its shape against aggressive wind - Wide perimeter brim casts extensive shade over neck and shoulders - Dark under-brim fabric dampens severe glare off water and light terrain - Crown venting ports release trapped heat without compromising sun safety - Rear one-handed cinch cord and heavy-duty chin strap lock fit in place **Watch-outs** - Cannot be crushed or rolled into small spaces without damaging the brim edge - Heavier and bulkier than standard ultralight sun hats
