I purchased two underarmor sweatpants and they are clearly knock offs - very poor quality, itchy, this awful somewhat elastic.
Their website says they have a hassle-free return policy. I do not consider me having to pay for shipping to return poor quality knock-offs to be hassel free.
Do not buy from here as the customer service is not helpful and just copies and pastes canned responses, the products are also poor and knockoffs - very uncomfortable and itchy.
