I never leave the house wearing them anymore and I think they are great. I work retail, and at the end of my shift, I’m usually the only one who still has a nice tuck. One day we were doing inventory, counting all the products in the toy department, and all my colleges (including the managers helping out) gave up on their shirts and wore them untucked for a couple of hours, my shirt stayed perfect.

I’m quite tall (193 cm) so I need to wear a larger shirt for sleeve length (especially the case for cheap shirts, such as my workplace uniform). But since I’m also pretty slim, this creates a good amount of extra fabric in my sides. The muffin top is removed with the KK&Jays, but some extra fabric is still popping up in the sides. I fixed this by messing around a bit with the points of the shirt where I attached the straps, and also doing a sort of backwards military tuck in the sides. Basically I just push the extra fabric in under the places, where the tension from the strap keeps the shirt in place. I found that this works relatively well. Definitely still a giant upgrade from before!

When raising my hands above my head, lower armhole shirts will result in the shirt moving longer up my body, and thus also a little bit out of my pants. However it’s really a slight movement, and the end of the shirt has never reached the top of my pants, and the tuck has therefore never gotten untucked. It does however create a bit of a muffin too after this, but this is easily fixed by moving the waist of the pants around a bit. This loosens the pressure from the belt on the shirt a bit, which instantly results in the tension of the KK&Jays straps to fix my shirt in place again. A quick finger into each of the “military-isk” folds, and the tuck is perfect.

This is a great product and I can highly recommend it. My only issue with them is, that the front right strap has gotten unattached a couple of times, resulting in me having to make a quick visit to the restroom to attach it again. Has only happened a couple of times, most of which were after I’d been sitting. I blame this on time maybe having loosened the strap attached to the sock a tad too much. Still definitely worth 5 stars!
