I've worn the traditional 4-clip suspenders for years and have always found them to be a lot of trouble coming loose after snagging on things, as well as damaging to my F-450's leather seats.
These side-clip Suspenders from Holdup are really nice... They're well-made and the clips, which are on the side and I have yet to snag, hold very securely.
So, after trying a pair of these "Holdup Hip-clip 2" Wide Trucker Style Suspenders", I was pleasantly surprised at how comfortable and little trouble they were.
They also come in several great colors, of which I purchased several.
Be aware that this type of Suspender attracts some attention!

TWO THUMBS UP!
