Q: Is Merino wool good for underwear?
A: Yes, Merino wool is excellent for underwear as it is naturally moisture management, breathable, and odor-resistant, keeping you dry and comfortable throughout the day. Its softness and temperature-regulating properties make it ideal for all-season wear.
Q: Are Merino wool sports bras suitable for high-intensity activities?
A: Yes, our Merino wool sports bras provide excellent support and moisture management, making them perfect for high-intensity workouts and activities.
Q: How should a sports bra fit?
A: A sports bra should fit snugly around the band and cups without causing discomfort, providing firm support without restricting movement or breathing. Ensure the straps are secure but not digging into your shoulders, and the band should sit level around your ribcage. Be sure to visit our sizing chart.
