Electronics & fitness trackers at REI
Last we checked, the outdoors doesn’t come equipped with electrical outlets. We’ve never seen batteries grow on trees. (If there are battery trees, they’re probably endemic to Australia.) Yet electronics can be useful or downright essential for anyone who spends time outside. REI carries an array of electronics from top brands like Garmin, GoPro and Goal Zero to support your adventurous lifestyle. Portable outdoor speakers can level up your next picnic. Satellite messengers help you stay in touch and safe. Headphones are a must for music-lovers who are into fitness. GPS watches track vital stats and can motivate you when hiking or running. And don’t forget solar panels and portable power to—ahem—motivate your electronics to keep running. Just in case you can’t find a battery tree.
