I have not used them hiking yet but have tried them on. I have average sized arms for a woman (120lbs) and I find them tight on my arms. I tried to fold the cuff over so it doesn't cut my upper arm so much and that relieved a bit of the tightness. Not sure how much I will use them, as even though I find them plenty long they binding my arms. Maybe they will stretch in time. I love the idea of these for convenience and sun protection.
