I also need to see how these hold up over time, but so far so good. Easy to put on and take off. Way too big/loose. Theyre comfortable, easy to wash, and seem durable enough for hiking! Im sure if I had bought these drives at a bricks and mortar store they would have been fine, but unfortunately the seller treats these like books; throw them into a box, put in a few air pillows and ship them out. My journey finding a perfect moisturizer has ended, not only is it amazing it?s also clean! I re-used the velcro surfaces with the normal command refill too with no problems. Thank u . Next time I know that I need to order smaller size. Returned for a refund.
