Editorial take

The Outdoor Research Sombriolet Sun Hat is a workhorse designed for sustained exposure in bright conditions. Its primary appeal lies in its comprehensive sun protection, provided by a wide, stiff brim that holds its shape even in a breeze. Constructed from a durable nylon ripstop, it feels robust without being overly heavy on the head. We've taken it through desert hikes, multi-day kayak trips, and hot fishing days, and it consistently delivers. The UPF 50+ rating is a given for sun hats in this category, but the Sombriolet stands out due to its thoughtful design elements that enhance comfort and stability. The internal TransAction headband wicks sweat effectively, preventing it from running into your eyes, a crucial detail when you're out for hours under a relentless sun. Laser-perforated side panels aid ventilation, though like any wide-brimmed hat, it can still feel warm on truly stagnant, humid days.

While it’s not the absolute lightest sun hat on the market, its weight is a fair trade-off for the structural integrity of the brim, which is vital for consistent shade. This hat packs reasonably well, though the brim's stiffness means it's not going to roll into a tiny ball – it's more of a fold-and-stuff scenario. The adjustable drawcord chin strap keeps it secure in gusty winds or during high-speed paddling, which is a major advantage over hats that simply blow off at the first sign of a breeze. Durability has been excellent; the fabric shows minimal wear, and the brim has maintained its shape through multiple seasons of hard use and even some accidental crushing.

Compared to softer, more packable sun hats, the Sombriolet trades some compressibility for superior, unwavering brim performance. It sits comfortably in the mid-range price-wise for quality technical sun hats, offering a strong balance of protection, comfort, and longevity. It's not the most stylish option if you're looking for a casual town hat, but for serious outdoor use where sun protection is paramount, it’s a reliable piece of gear that gets the job done without fuss.
