I accidentally bought the wrong size and ended up not being able to wear it. Now that the cold season has arrived, I think it can be worn as is or over a jersey. The two layers of fabric overlap, creating a thin yet warm structure. Purchased at an ASICS store. I think it was quite expensive. I forgot the price. Just in case, it's large for those who usually wear LL. Will be folded for shipping. #Keeps Warm - Brand: ASICS - Color: Black - Size: 2XL - Material: 100% Polyester - Design: Simple #asics #paddedjersey #asicsTrainingWearXXL #windbreaker Thank you for viewing.
