Very comfortable and the fabric feels like it gives well. I like the stripe by the back of the knees, versus the weird angled crease seam from hip to under butt of the Tiro 24 Training Pants that I could feel as I wore them so returned. Wish they had slim fit version because there's more gathering folds on the legs than I'd like. Fabric definitely seems slightly thinner and lets even more light through when holding up to light. The waistbands on all Tiro pants I've had for years are incredibly forgiving (and adjustable with the drawstring) and have lasted with me through weight gain and loss--it's just the legs and lower hip area that eventually becomes too tight, but never the waist, interestingly enough!
