When summer’s long days coax you into ever-longer rambles, reach for these warm-weather essentials. They’ll keep you wandering—in comfort.

Patagonia Nine Trails Pack 20L
Knowing that any grocery sack can haul a water bottle and jacket, Patagonia focused on maximizing comfort: A layer of perforated foam in the back panel solves the sweaty-back syndrome by venting heat and moisture, and thermo-moldable mesh eliminates pressure points by conforming to your back’s every curve and gully. A women-specific 18L version features narrower straps and fits shorter torsos. patagonia.com, $129

Tecnica Forge Leather GTX
Blisters, begone: The market’s first heat-moldable hiking boot feels broken-in from Day One, thanks to a custom-fit process that warms the boots in a special oven before installing them on your feet. The result is a supremely comfortable boot that’s supportive enough for rugged paths, regardless of weather. Its Vibram Megagrip outsole provides sticky traction on uneven terrain, and the Gore-Tex membrane seals out rain. tecnicausa.com, $250

ROKA Rio Ti
Titanium makes these aviators lighter than most metal-rimmed sunglasses: Weighing just 18 grams, the Rio Ti is unobtrusive enough for hiking, running, and cycling. The nose pads feature a patented material (inspired by sticky gecko feet) that keeps these frames from slipping down even the most sunscreen-slathered nose. And premium nylon lenses by Carl Zeiss Vision provide sharp, contrast-enhancing views. roka.com, $260 ($300 for polarized lenses)

Marmot EVODry Eclipse Jacket
Most water-repellent fabric treatments are awful for the environment, yet Earth-friendly alternatives haven’t held up in hard rain. Enter Marmot’s new EVODry technology, which uses sustainably-produced recycled nylon that will actually keep you dry even in extended downpours and drenching white water. Plus, this lightweight, 13.4-ounce jacket packs down small for easy stowage. marmot.com, $250

An all-organic instant tea that actually delivers the full flavor nuances of brewed loose-leaf, Cusa turns off-flavored hotel tap water into a tasty summer cooler and becomes a cup of comfort at any temperature.
