The best underwear for the gym

Founded by entrepreneur Renata Black, this high-tech panty brand gives 20 percent of its net profits to Seven Bar Foundation, an org that provides loans to impoverished women. Each ultra-lightweight, seamless thong ($22) comes with a personal testimonial from a woman who’s received a loan to start her own business. What better way to feel strong and get motivated? (Also available to select Equinox shops.)

Just-launched brand The Eighth describes itself as “a mashup of all the good things in life: art, music, sex, culture, and sport.” The Sport in limited edition toile print “Wears the Eighth” ($78) is all these things and more; the luxury briefs feature a chafe-resistant second skin fit, silky smooth compression fabric, and tagless care for streamlined performance.

Minimalist activewear brand Cory Vines proves there’s beauty in simplicity. These tagless, seamless, sweat-wicking panties ($12) provide full coverage, but without the embarrassing lines. Plus, they are so light you might even forget they’re there.

Made with Lululemon’s own Luxtreme fabric, the Lock ‘Em Down Trunk ($32) is designed for maximum comfort and support whether you’re tearing it up on your bike or in the board room. Plus, the four-way stretch fabric is designed with shrink-resistant technology, ensuring that your shorts will be in it for the long haul.

From activewear and lifestyle brand Lolë (an acronym for Live Out Loud Everyday), the Ritzy Shorts ($40) boast quick-drying, antibacterial fabric and booty-toning compression bands, making them a perfect choice for some sweaty, hot yoga or a barre burn class. Worried about going commando? These seamless boyshorts feature double the yarn for complete coverage.

If you’re the adventurous type, these ultra-versatile briefs ($30) are about to become your new best friend. Super soft, sweat-wicking mesh fabric and top-notch odor resistant technology combine to make them a great option for any activity, so it doesn’t matter whether you’re scaling Mount Everest or training for a triathlon—these briefs have you covered.

From Carrie Underwood’s new fashion-forward fitness brand, this lightweight thong ($15) provides moisture wicking and odor-free antimicrobial protection for total comfort and long-lasting wear. Plus, the smooth hems prevent pantylines so you can focus on your workout and not your waistband.

These flashy boxershorts ($25) use heat-dispersing mesh fabric and moisture transport technology to keep you feeling as cool. They also feature four-way stretch fabrication for total mobility, and anti-odor technology, making them ideal for your more intense workouts.
