Jaybird Tarah Earphones ($100)

Music is a must to stay focused in a noisy gym. These Bluetooth earphones are comfortably snug, sweatproof, and good for six hours on a single charge.
Hill City Body Map Train T-shirt ($48)

Not too loose and not too tight, the Body Map Train is made from Tencel, a durable fiber derived from wood pulp that鈥檚 surprisingly soft to the touch.
Ascent Whey Protein Powder ($40)

This natural whey blend is easy to digest and offers a 25-gram boost of protein (the equivalent of four large eggs) with every scoop.
Salomon Predict RA Shoes ($160)

Six channels in the sole help the Predict RA flex with your foot. The 25-millimeter stack height cushions during box jumps and sprints. And the tightly knit upper keeps you locked in.
Fits Light Runner Low Socks ($18)

These were a tester favorite, thanks to a blend of nylon, Lycra, and merino that offered breathability, odor resistance, and durability.
Lululemon Command the Day Duffel ($158)

Thirty-seven liters may seem big, but testers loved the dedicated pockets for shoes, laptop, and water bottle. The water-repellent fabric is easy to clean, too.
Saxx Kinetic Boxers ($37)

Luxurious enough for everyday wear, these boxers feature the (unfortunately named) BallPark Pouch and flat seams that don鈥檛 chafe.
Hill City X-Purpose Shorts ($58)

Hill City鈥檚 shorts are made with a water-repellent and wrinkle-resistant nylon fabric. Plus, they come in three different lengths, which means every tester found a pair that fit.
Purist Mover Water Bottle ($48)

The Mover looks like plenty of other stainless-steel carafes, but it鈥檚 lined with a thin layer of glass, so the bottle won鈥檛 absorb the flavors of your protein powder.
