CUSTOMER REVIEWS

Scott D.

“Brilliantly comfortable. Daily wear. Exercise. Lounging with Netflix or a book. The boys are supported yet free to move. Genuinely the best of both worlds. Discovering Sly’s a few years ago was an eye opener. The others out there just don’t measure up for softness, comfort, function and style.. With the new XXXL size, the now fluffy sized me is still in the game. Not to mention, the other-half loves the funky designs. Oh! Forgot to mention the pocket. WTH? A pocket?! Yes! A freakin’ pocket to put your phone in, if you’re just cruisin’ the house in your Sly’s. Genius.” – Scott.

Designs are amazing and the reason I thought to give them a go. Was worried about sizing especially in the seat, but it was spot on. Good fit. Not completely confident about the elastic in the leg but time will tell.
