Black and yellow full suit, size S, with a zipper for a comfortable fit. - Color: Black/Yellow - Size: S - Design: Long sleeve/Long pants - Features: Full suit/With zipper Thank you for viewing. Thickness is 5mm. It's fleece-lined, so I think it will be warm. I bought this here, but the upper body didn't fit, so I'm unfortunately selling it. I am 48kg and 155cm. The lower body fit just right, but the shoulders were too wide, so it was quite tight. Please refer to the images for the size. I think it's suitable for slender people. There is some dirt on the knee area, but overall it's a clean item.
