Peloton's Jess Sims's Must Haves Include a $3 Caffeine Eye Mask

When you're constantly on the go, good sleep is nonnegotiable, and Sims has found the travel hack that keeps her rested anywhere. "I love my Dreamegg Portable Noise Machine ($19, originally $20)," she says. "I'm in hotels every week, and sometimes they're loud in the hallway or on a major highway, so a sound machine is a must! This one's rechargeable, portable, and has some great sound options."
