For the price i would expect really more. It's comfy to transport on your back, no hesitation, but protection of the speaker itself is minimal. It seems Bose desiegned that backpack for dust protection cause it will not survive any bigger bump. I've bought Thomann case for 39€ just to compare these two cases. And i can tell you for sure- if you want speaker protecion- go for thomann case. It's way cheaper then Bose and it will do way more in case of protection. If Bose would do thick padded walls, top and bottom (wich they really should do considering their price) as it's done in Thomann case- maybe i would recommend to buy this Bose backpack. But for now- go for Thomann case, its really better.
Given that the Bose S1 is so compact and portable I decided to also purchase the Backpack. The S1 fits perfectly into the main compartment with the top section ideal for cables, mics, pedals (1-2) etc. The quality of the backpack is top class and well finished. While it is a bit expensive it is worth it to protect the S1. My hands are free to carry a guitar with everything I need for a small gig in the backpack.
Well made, plenty of space for cables, mics and other gear. Comfortable to wear too, which you'd hope considering how much it costs! The speaker itself is a touch on the heavy side, so if travelling to gigs on public transport, this is going to be a lifesaver.
