Amazon EssentialsMen's Fleece Open Bottom Sweatpant (Available in Big and Tall)OEKO-TEX STANDARD 100

My husband is 6'5" what size will be long enough

Are the ankles at the bottom elasticated or non elasticated? Thanks.

I chose the size as 35-37 waist but when i went to check out the joggers' size was quoted as "s" in both cases. can i trust that these will fit?

Where are the tall options as written in the product description ‘(available in tall & big)’ but I can only see big options.
