I Squatted, Sprinted, and Planked to Find the Best Workout Underwear

July 7, 2026 | "I’ve been testing the thong from Oregon-based brand Branwyn — it contains mostly merino wool — and it’s been my favorite because it has some stay-put compression but not enough to cause discomfort."

Brenley Goertzen of The Strategist tested a range of workout underwear across strength training, running, cycling, and Pilates, evaluating each for comfort, moisture management, chafe prevention, fit, and visibility under leggings. The BRANWYN Essential Thong was named a top winner and the reviewer's overall favorite, praised for its Merino wool construction, stay-put compression, comfortable fit, smooth appearance under leggings, and ability to soften with wear, while outperforming other Merino options tested.
