Great quality!
2XU is unique and the only "mainstream" retail store that carries these types of tights. While I think the quality and design is fantastic, I feel like their sizing is not great or inclusive. I am 5'3, 165lbs with an athletic build, but carry weight around my waist. I found that the large tights were tight and uncomfortable - making it very unlikely that I would wear these tights when and if I needed them, so I ended up exchanging the large for an XL. The XL is a tad loose, but I would prefer them to be loose than uncomfortably tight. I also think it's strange that someone larger than me would not be able to buy this product - especially as I consider myself to be "average" in size.
All in all, I do think it's a great product, which is why I would recommend it. I just think the sizing isn't the best.
