I bought this back pack a while ago and thought I should share it with the forum.
I bought it for motorcycling but never saved up enough money for the motorcycle I wanted. I kept the bag, and then when I recently took up bicycling (mainly mountain biking), it started coming in very handy.
Below is the website I got it from. It is an English website and I live in the US, but they shipped it to me in a timely manner. The main website is currently down, but there is a link on the page to an alternate site that sells the same items.
Here is a direct link to the shop page. The bag is at the bottom.
The Back pack is of pretty good quality. It holds all of my tools and various bicycle accessories I like to bring (chain, lock, pump, wallet etc...). The reflective strips are sewn on, sturdy, and are very reflective from many directions. There may be higher quality high-vis bags out there, but my experience with this one has been good, so I thought I would share instead of just lurking.
