Baseball caps are not desert hats. That’s the short version.
The longer version: a baseball cap protects your forehead and your nose. Your ears, your neck, and the sides of your face are completely exposed. On a 4-hour ridge hike in June, that’s a sunburn on three-quarters of your head and a real risk of heat exhaustion. The hat you wear matters more than almost any other piece of gear in the desert.
Why Brim Size Matters More Than You Think
A 2-inch brim and a 3.5-inch brim sound similar. On the trail they’re completely different.
At solar noon in southern Arizona, the sun is nearly directly overhead. A 2-inch brim casts a shadow that covers roughly your eye sockets. A 3.5-inch brim drops shade all the way down to your chin and around to the back of your neck. That difference is the gap between a pleasant hike and arriving at your car with a burned neck.
The back brim is what most hikers never think about. Even hats that advertise a 3-inch front brim sometimes taper to 2 inches or less in the rear. Read the spec sheets carefully, or look for hats that specifically list “full brim” or “all-around brim.”
3 inches minimum. 3.5 is better.
Top Picks
1. Outdoor Research Seattle Sombrero
This is the best wide-brim hiking hat made. The full 3.5-inch brim runs all the way around, front, sides, and back, with no tapering. It’s UPF 50+, crushes flat for packing, and springs back to shape without any effort. The chin cord is adjustable and stays out of the way when you don’t need it.
The only thing some hikers complain about is that it’s not vented. On a hot day with no breeze, it can feel warm on top. But the protection it delivers on exposed terrain is unmatched at this price point.
2. Tilley LTM6 Airflo
The Tilley costs $25 more than the OR Sombrero and trades 1 inch of brim width (2.5 inches vs. 3.5 inches) for a mesh crown panel that genuinely improves airflow. If you run hot or hike in humid desert conditions (Sonoran monsoon season, for example), the ventilation difference is noticeable.
The LTM6 floats if it hits water, which matters for canyon hikers in flash flood terrain. Chin strap is standard. The 2.5-inch brim is smaller than ideal, use it with a sun hoody to cover the neck gap, but the hat’s overall quality is exceptional and it lasts years longer than budget options.
3. Sunday Afternoons Adventure Hat
At $48, this is the best value wide-brim option for hikers who get out a few times a season rather than every week. A 3-inch brim (not 3.5, but close), UPF 50+, a vented crown, and a chin strap. It doesn’t crush and recover as cleanly as the OR, but it holds its shape when stored flat.
The Adventure Hat is a good first desert hat. Most people who buy it end up using it for years before upgrading.
Also Worth Knowing
The REI Sahara Bucket Hat ($35) is a solid compact option. It folds down to almost nothing and the UPF 50+ rating is legitimate. The brim is only 2 inches, so it’s not a ridge-hike hat. It’s a pack-it-in-your-bag-in-case-of-sun hat. Fine for canyon trails with some tree cover.
Backpacker Magazine tested the KUHL Sun Blade in desert conditions and flagged it as a strong performer for hikers who want a more structured, fitted feel than a crushable trail hat. It runs narrow in the brim (2.75 inches at most) but the fit is excellent for people who find the Tilley too loose.
What to Look For
Brim size: 3 inches minimum, all the way around. Check that the back brim matches the front.
UPF rating: 50+ is the right call. UPF 30 blocks 96% of UV. UPF 50+ blocks 98%+. That extra 2% matters on a 6-hour desert day.
Ventilation: A mesh crown panel or eyelets help significantly in still air. The OR Sombrero skips this, and most people don’t notice. But if you’ve ever worn a non-vented hat in the Sonoran summer, you’ll appreciate the airflow.
Chin strap: Required for open ridgeline hiking. Optional for shaded canyon trails. Non-negotiable for anything with exposed scrambling.
Packability: A hat that crushes flat and recovers its shape lives in your bag between uses. A hat that holds its shape only when stored properly gets left behind. The OR Seattle Sombrero and Sunday Afternoons Adventure Hat both crush and recover well.
The Baseball Cap Problem
A 6-inch bill on a baseball cap seems like real sun protection. It isn’t.
The bill only covers a narrow band in front of your face when the sun is directly ahead of you. In desert terrain, the sun is overhead, to the sides, and reflecting off light-colored rock and sand. Your ears are fully exposed. The back of your neck is fully exposed. A baseball cap with a neck gaiter is a partial fix, but at that point you’re already halfway to a wide-brim hat in terms of coverage and hassle.
The data is clear: ear and neck exposure during outdoor activity is the leading site for squamous cell carcinoma in hikers. A hat that doesn’t cover those areas isn’t a hiking hat, it’s a fashion choice.
Get a 3-inch brim. The OR Seattle Sombrero at $60 is the right call for anyone who hikes in open desert terrain more than a few times a year. Start there.

Frequently Asked Questions
What's the minimum brim size for desert sun protection?
3 inches all the way around. Anything narrower leaves your ears and the back of your neck exposed. On an exposed ridgeline at noon, a 2-inch brim casts almost no shadow on your neck. You'll feel the difference after two hours. If you can only find brim size listed in front measurements, skip it, the front brim and the back brim need to match.
Do I need a chin strap on a desert hiking hat?
Yes, if you hike anywhere with wind or open ridgeline exposure. A hat that blows off once on a scramble section is a hat you might not get back. Most desert terrain is exposed, no tree cover to break wind. A chin strap doesn't need to be tight; it just needs to exist for the moments when a gust hits. Look for a breakaway or adjustable cord, not a stiff plastic clip that digs in.
Is a bucket hat good for desert hiking?
A vented bucket hat is fine for shaded canyon trails or casual desert walks. It's not a substitute for a wide-brim hat on exposed terrain. The brim on most bucket hats is 2 inches or less and doesn't protect your neck at all from high-angle sun. The REI Sahara Bucket Hat is the best version of this style, compact and UPF 50+, but it's a convenience item, not a protection item.
Can I wear a hat instead of sunscreen?
No, but a wide-brim hat dramatically reduces how much sunscreen you need. A 3.5-inch brim cuts UV exposure to your face, ears, and neck by over 70% compared to no hat. You still need sunscreen on your face, the back of your hands, and any other exposed skin. But you won't need to reapply nearly as often because the hat is doing most of the work for covered areas.
