Step into AMAZING every morning.
“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.
Have not bought any undies from anywhere else.
Still rocking my SLY’s I bought years back.
Best undies I have ever had.
Great customer service, super comfortable and do NOT ride up *at all* unlike 99% of other brands! highly recommended!
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.
I have 5 men wearing them.
Lining up birthdays & Christmas.
The youngest demands them now LOL.
I love your collection.
They’re my favourite to wear.
Comfort with support unparalleled by other brands.
Awesome fit and very comfortable.
Snug where they need to be and roomy where needed.
Nice and comfy.
Fit well and strong elastic waist band.
I’m well and truly a SLY lover.
Great fit.
You can feel the quality of these undies.
