These sweatpants are nice. They’re not thick and not too thin. I would call them medium weight. I would say that the ideal temperature to wear is between 60 and 75. Also, they’re not fleece, contrary to what the descriptions say. They’re just plain cotton sweatpants. Very comfortable, soft, and airy with a small waffle-like pattern on the inside.What I like is the fact that the waistband is wide and not thin like many other sweatpants I’ve tried. The stretch waistband is the height of the top section as seen in the photos. Having such a wide or tall stretch waistband keeps the pressure spread-out around your waist rather than concentrated which feels a lot better. The stretchy part is also not too strong which can be constricting. It’s tight enough to keep the pants up.I bought a medium which fits perfectly with my 30” waist and 30” inseam.
