So this is the Velcro version of Northwater scabbards, they have an internal plastic 'sheath' that slides out and makes it very easy to slide the paddle in/out, and it keeps them open (ala ABS pipe). There are three separate Velcro tabs to attach to lines. It's super quick to put on/take off, I'd recommend it if you're looking for a bow-type removable device.
I don't consider a pair of underwear strapped on your bow a good look, so I'd consider this a win. Just my opinion.They don't look as much like a tiny pair of pants though, so a bit of a drawback.
