Now you have to completely unbuckle the top strap, and re-buckle it to get it back on. 5in wide spare on the back. But they work like theyre supposed to do all is well. Complete sound blocking from any background noise. I have worn Chacos for decades - they are incredible! This dress was not what I expected. My tennis shoe size is 8 and these fit perfectly, even with socks. The sound quality is also incredible. Make sure you use a rear-facing camera when you back into parking spots or your garage. It is highly recommended for those who are looking for easy-to-install, sturdy and spacious roof bag.
