Perfect gear for the desert: sunglasses, hydration pack, trail runners, more.

1. The Sun Blocker Editor's Pick: Best Value GoLite Chrome Dome   An adventure umbrella? Surprisingly, yes. The 22-inch (56-centimeter) Chrome Dome ($30; www.golite.com) wards off the sun better than any sunscreen and weighs just ten ounces.
2. The Bike Tire Slime SRT Tubeless Tires   Ah, Slime. Nothing fends off cactus flats like the goopy green tire sealant—and now you can skip the messy installation with pre-Slimed tires. The 2.0-inch (5.0-centimeter) cross-country tires ($42; www.slime.com), our favorite, fit on tubed or tubeless rims.
3. The Astronomer Editor's Pick: Best Innovation Celestron SkyScout   A thousand points of light can be pretty confusing unless you have the SkyScout ($400; www.celestron.com). This GPS-driven device instantly identifies objects in the night sky—just point, shoot, and learn the name and history of the star, planet, or constellation in question.
4. The Sunglasses Editor's Pick: Best Comfort Smith VTI For all their style, Smith shades typically haven't been the first choice for hot-weather cardio; sport-specific Oakleys or Rudy Projects were more likely to get the nod. But the new VTI dual-lens shields ($159; www.smithsport.com) are changing that. Best for cycling or running, the feathery frame has all the heft of a butterfly wing, the lens optics are crisp, and venting is so good that fogging is rarely a concern.
5. The Hydration Pack Camelbak Octane 14   With the carrying capacity of a small dromedary, the new Octane 14 ($95; www.camelbak.com) is one stealthy little exercise in versatility: It's light enough for trail running, vented enough for the heat, and adaptable enough for a one-hour or daylong hike. In short, it's the bomb.
6. The Shirt Patagonia Capilene 1 Crew The fast-drying, gossamer Capilene 1 Crew long-sleeve tee ($38; www.patagonia.com) might be the ultimate desert shirt: adept when hiking, running, relaxing, or (in its original use) as next-to-skin insulation. All that and it's made from 100 percent recycled fibers.
7. The Canyon Shoe La Sportiva Exum River   There aren't many canyoneering kicks, period, and the Exum River ($100; www.sportiva.com) is the rare one that's as comfortable on dry trails and slickrock as it is in wet, mucky slots. The shoe's sticky rubber tread handles rock climbing and scrambling, and its hiking-shoe chassis makes it supremely stable. The standout feature is a strap that cinches down your heel as solidly as a rock shoe does.
