After a few days, the process of removing and putting on the bumper definitely gets smoother, but I wouldn't exactly call it something that could be done mindlessly, unfortunately And you're definitely, right, those are the kind of events I had in mind when addressing the best use cases for the bumper, although like you said once a certain sporting event gets treacherous enough, I'd imagine I'll be taking my $600 watch off in the first place.That is incredibly ugly/bulky.
Honestly, I wouldn't be opposed to some type of bumper/cover if it could be installed and removed very quickly.
For example, if someone likes to do obstacle races (Tough Mudder, etc.) and would still dare to wear the watch doing one of those, it might be nice to have a cover that you could quickly put on before the event and take it off as soon as you didn't need that level of protection.
I don't know. Laudable concept I guess, but yeah ... fugly.
