These are the first joggers I've owned that actually feel light enough to forget I'm wearing them, and the fleece inside is soft without being bulky. I've been lounging in them all weekend and the waistband doesn't dig in at all.
Wore these on a chilly morning run and forgot I had them on by the second mile. The fleece is genuinely light, not bulky like my old sweatpants, and the bamboo fabric feels almost silky against my skin.
