These are made of soccer fabric, which feels cool and comfortable. The length is about knee-covering. How about them for loungewear or pajamas? They have an elastic waist, making them very easy to wear. I bought them as loungewear in August of this year, but they were too big, so I've been storing them. The tag says 3L, but I think they'll fit LL or even smaller. Please check the size details below. I've washed them at home after trying them on. Approximate measurements: Waist: 33cm Total length: 83cm Inseam: 52cm Rise: 38cm Pockets on both sides. #Loungewear #LL #LargeSize #RelaxedFit
