Warm & Comfy
These pants are super warm & very comfortable. I was slightly disappointed when I got them as I thought the fabric would kind of drape and hang off your hips but as they are a fleece, they are a bit more firm/slightly stiff. That said, they are still really comfy. For sweat pants, the fit is relatively flattering but I still wouldn't be overly keen to wear them outside the house.
I too found the sizing to run a bit big... I bought my usual TNF size (small) but should have gone for the XS. They have a drawstring around the waist, so I haven't bothered to exchange for the smaller size - they are fine for lounging around at home. I am 173cm (5ft 6), 62kg (136lb).
One of the side seams came undone near my hip on my 2nd wear, which surprised me but nothing a needle & thread couldn't fix.
Despite the slight disappointment of them being a bit more casual than I thought, I find myself diving into these as soon as I get home from a long day at work!
