Hold up… Are we talking about the same Decksavers here? I mean to each their own, but in my opinion they are neither hulking nor ugly - it’s just clear plastic sized specifically for whatever model of gear you have. Boring perhaps, but not ugly.
Also, if your “mobile environment” is enough to break a Decksaver, your gear is already toast. Those things are bloody indestructible - you can quite literally run over them with a car and they come out fine
Venting shouldn’t be an issue - players shouldn’t be venting out the top and Decksavers don’t cover the sides.
