I'm 5'11" tall and the 36" leg is great. I like the cuffed ankle, and they're a comfortable fit generally. Personally I think the leg should be a bit slimmer, but for wearing at home they're ok. The material is cosy and soft. These are light to mid-weight, so are suitable for everything except Winter IMO. I haven't washed them yet, but the poly cotton mix should wash well.
