Wearing it under a skiing helmet is still possible but gets painful quickly because it presses into the ear too much. I also use these on my work laptop which has the Dolby Audio EQ on it; it’s great because it allows me to customize the levels to get it to a perfect balance. I wont hesitate to buy here again. Perfect fit and fantastic texture. She loves the colors and comfort of them! when new, fit like a glove, then stretched out with wear. 5-8 W US size I ordered the 8-9 size and it fits perfectly. Wanted to try them on! I dont want to wear it for 8 hours but if I did I could and I feel it would be comfortable it fits my body like a glove. I would say if youve never worn an under bust corset (like me) that you should watch videos on proper lacing.
