Motorcycle - Traverse Backpack

This thing is awesome! Been using it every day since I got it a couple weeks ago! There's a ton of pockets that are all easy to get to, the zippers stay put while riding, and it works great aerodynamically! It's somewhat similar to a turtle shell backpack from an unnamed brand. There's two small downsides that I've gotten so far. . . One is that the chest strap freaks me out lol. The extra parts of the strap will bunch up and/or come loose while I'm riding, so when I get to a stop, & go to grab the buckle to take off the bag, it spooks me a bit cause I thought something was wrong. The buckle itself is perfectly fine though! The other one is possibly a user-error type of thing, the backpack does sit slightly higher on your back, which is great because, it never comes in contact with the back/passenger seat! The problem is the top of the bag, specifically on my sportbike. In a very leaned-over riding position mixed with one of my long-boi race helmets, they come in contact with eachother all the time, which is very annoying! It's only with one helmet on one specific bike though, I only get that issue with that one specific combo.
