What Our Gearhead(R) Experts Are Saying:"I switched to the Crossover Bikini Underwear for long active days, and the TENCEL fabric makes a noticeable difference in breathability compared to anything I had worn before. The full-coverage gusset and merrow seams mean there is nothing digging in or shifting around, no matter how long the day gets."The Huha Crossover Bikini Underwear is built around the idea that the layer closest to your skin deserves as much thought as everything on top of it. TENCEL Modal and Lyocell fibers deliver a softness and breathability that synthetic fabrics simply cannot match, and the crossover waistband moves with the body through anything the day brings without digging in or bunching up.
