Spending long days on the trail under an unforgiving sun is no joke. Whether you’re hiking, backpacking, or thru-hiking, protecting your skin from UV exposure is just as critical as staying hydrated. Sunscreen helps, but it fades with sweat, dust, and time. That’s where the best sun hoodies for hiking step in. A good sun hoodie doesn’t just shield your skin — it keeps you cooler, drier, and more comfortable for mile after mile.
After digging into hundreds of miles of testing and real-world use from backpackers, here’s your complete guide to choosing the right sun hoodie and the best models worth considering today.
Key Features to Look for in a Hiking Sun Hoodie
Before jumping into the best picks, it’s important to understand what separates a great sun hoodie from an average one. These are the features to keep in mind:
UPF Rating
UPF (Ultraviolet Protection Factor) measures how effectively fabric blocks UV rays. A UPF 15 shirt blocks about 93% of UV rays, while UPF 50 blocks 98%. The difference might sound small, but for those with fair skin or at high altitudes, it matters. For most hikers, UPF 30–50 offers the sweet spot.
Fabric: Synthetic vs. Merino
- Synthetic (polyester/nylon blends): Lightweight, durable, quick-drying, and often more affordable. Downsides: they can hold odors.
- Merino wool: Naturally odor-resistant, breathable, and comfortable. Downsides: warmer, less durable, and more expensive.
- Blends or plant-based fabrics: Some brands use Tencel or bamboo for softness, but they tend to dry slower.
Weight and Breathability
A sun hoodie is your hot-weather base layer. You want fabric that breathes and doesn’t trap heat. Thinner synthetic models like the Outdoor Research Echo feel almost invisible, while thicker options like the REI Sahara Shade offer more durability but can run warmer.
Moisture-Wicking and Quick-Dry
Sweat is inevitable on trail days. Look for fabrics that pull sweat away from your skin and dry fast. Quick-dry fabrics prevent that clammy feeling and keep you comfortable when temperatures shift.
Fit and Comfort
Fit is about preference. Some hikers like a slim, athletic cut; others prefer a looser, breezier style. Important details include:
- Hood shape: Full coverage that stays put in wind is best.
- Thumbholes: Keep sleeves in place and protect the backs of your hands.
- Length: Longer hems give more coverage but may feel bulky for shorter torsos.
Now, let’s dive into the best sun hoodies for hiking in 2025.
Best Synthetic Sun Hoodies
Cotopaxi Sombra Sun Hoodie
The Cotopaxi Sombra has earned a cult following among thru-hikers. It delivers UPF 50+ protection, durable fabric, and a scuba-style hood that layers well over a cap. Despite months of heavy use, hikers report no holes — rare for lightweight synthetics. It’s not the lightest, but the balance of durability, breathability, and protection makes it a top pick.
Outdoor Research Echo Hoodie
If you want the lightest, most breathable option, the Echo is hard to beat. At UPF 15–20, it offers lower protection than others, but it’s incredibly airy and dries faster than anything else tested. Perfect for sweltering climates where breathability matters more than maximum coverage.
Backcountry Tahoe Sun Hoodie
This option combines UPF 50+ with a soft, stretchy fabric. It feels more comfortable than most synthetics, with a flattering fit. Great for backpackers who want high protection without sacrificing comfort.
Columbia Summit Valley Sun Hoodie
The Summit Valley strikes a balance with UPF 50+, lightweight fabric, and Omni-Wick technology to manage sweat. Slim but not tight, it’s breathable on hot days but does snag more easily than tougher hoodies.
Arc’teryx Taema & Cormac Hoodies
Premium but worth it. The Taema (women’s) and Cormac (men’s) use Arc’teryx’s Phasic LT fabric: UPF 40+, breathable, moisture-wicking, and odor-resistant. They’re pricier but more durable than ultralight competitors.
REI Co-op Sahara Shade Hoodie
A favorite for value hunters. For $50 and UPF 50+, the Sahara Shade is soft, stretchy, and comes in a huge size range (including tall, plus, and even kids). It’s slightly thicker, making it better for cooler hikes or those who prefer more coverage.
Patagonia Capilene Cool Daily Hoody
A versatile choice for trail-to-town use. With UPF 34 on average, this hoodie feels casual but still technical. Breathable, quick-drying, and affordable, though it lacks thumbholes.
Outdoor Research Astroman Air Hoodie
This one blends stretch and durability with UPF 30–50+ depending on color. Its half-zip adds ventilation, though the fit runs long. Great for taller hikers who want extra coverage.
Best Merino Wool Sun Hoodies
Ridge Merino Solstice Lightweight Hoodie
For those who prefer natural fibers, the Solstice offers UPF 30+, odor resistance, and comfort even after days without washing. The fabric is soft and regulates temperature well, though it won’t dry as fast as polyester.
Icebreaker MerinoFine Ace
A premium option at a premium price. With UPF 40 and merino breathability, it’s ideal for hikers who value odor resistance and sustainability. Expensive, but one of the best-performing wool hoodies tested.
Zpacks Mirage Hoodie
A merino blend with a zipper for extra ventilation. Great for high-altitude or cooler environments, though some hikers find zips cause neck irritation.
Hoodless and Button-Down Alternatives
Not everyone wants a hood. Some prefer long-sleeve sun shirts or button-downs:
- REI Sahara Long-Sleeve T-Shirt: UPF 30–50+, soft, stretchy, and available in both men’s and women’s cuts.
- Patagonia Capilene Cool Daily Long Sleeve: Same fabric as the hoodie but without a hood. Great for layering.
- REI Sahara Button-Down: A durable, vented classic with UPF 50. Popular with backpackers who like a more traditional hiking shirt.

Final Thoughts
There isn’t a single “best” sun hoodie for every hiker. The right one depends on your climate, budget, and personal preference. If you want maximum breathability for hot desert trails, go with the Outdoor Research Echo. If you need all-around durability and coverage for long-distance thru-hiking, the Cotopaxi Sombra is a proven workhorse. For value and inclusive sizing, it’s hard to beat the REI Sahara Shade. And if odor control is your top priority, merino wool options like Ridge Merino or Icebreaker will keep you fresher longer.
At the end of the day, the best sun hoodies for hiking do more than block UV rays — they keep you comfortable, protected, and ready to push for that next summit. Choose one that fits your needs, and you’ll never go back to short sleeves and sunscreen alone.
