The ribbed rubber has just enough flex that I can turn my head without the hose kinking, which was my main worry. Feels fresh and pliable too, not that stiff old surplus stuff people warn you about.

Snapped right onto my mask and canister with no fuss, and the rubber still smells fresh instead of that old surplus rubber stink. The flex is stiff enough that it holds its shape but bends where I need it.

The ribbed design makes this hose far more flexible than the old surplus ones I've used, and it connects perfectly to both my mask and canister. Feels solid and new, exactly what I needed for my setup.
