I think you received different fabrics than me. My sky blue oxford is similar in colour to the sky blue summer chambray, while my classic blue oxford is similar to PRL's blue oxford. The blue oxford is also a little bit thicker.
I have a messenger bag from Bric, and I've been using it for three-four years and I didn't have any problems until late May when one of the shoulder strap broke off. But I was able to glue it to the bag again and it is as good as new.
