Thank you for viewing. I used it for about 2 hours. There are no particular stains or odors. It is a US size, so it is a size L in Japan. If you have any other questions, please leave a comment. The following is an excerpt from the official text: This lightweight multi-glove uses GORETEX INFINIUM and is excellent for wind resistance and breathability. Even though the fabric is thin, its excellent wind resistance prevents body heat from being taken away even when exposed to strong winds on ridgelines. It also has waterproof properties, so it can handle some rain. (*Note: Seam sealing is not applied.) ・GORETEX INFINIUM is used on the back of the hand. Excellent breathability suppresses stuffiness when sweating. ・Recommended for mountaineering in the high mountains above the treeline in summer, and for hiking in late autumn or when there is remaining snow, or for approaches. ・The palm side uses artificial leather, which is characterized by high durability, grip, and a soft, familiar feel. It also has wind resistance and is effective for use in high-altitude chain areas and ladder areas. ・Touch screen compatible
