Hmmm, I'm a 34, I got the sweatpants in Medium. The waist stretches pretty well for me, but the fit in the legs and everything else is spot on. Obviously not tight, but not overly baggy like 99% of the sweatpants out there.
My friend has a pair of those fleece sweats ryosuke has but in size M. PM me if you're interested. $110CAD.
I personally think it's an interesting texture for sweatpants. Not sure if I'll look good in them though. The same pattern in the tiger fleece hoodie is super awesome though. I should've been proxying those instead.
