I own three Gore jackets, shorts and a helmet cover and I've been very happy so far. Hi quality and no-nonsense products. So I was expecting another great product BUT these Gore tights are really TIGHT! I usually wear medium in LG and PI and large in Gore and Castelli but their large here is more like medium around the waist. Length is good thow. I'm not fat at all (5'10" 163lbs with 34" waist) but I felt very unconfortable when I tried them on. Sitting on the saddle was a nightmare because there is no elasticity at all and I think the Abrasion-resistant fabric is the main culprit. Unfortunately I had to return this. If you are planning to buy maybe you'll have to size up but then the legs might be too long. Maybe you have to be extra-thin and bone skinny to fit in these.
