I just got the medium oblique and I LOVE it!!! It’s so lightweight and easy to carry. The opening is smaller, but I think the purpose of that is so things don’t come out of the sides. I didn’t think I was going to live it as much as I do. The strap is such a great length and not too wide, which I love. It’s also easily adjustable.
I have the medium oblique too and absolutely adore it. Easy to use and don’t have to be too fussy with it. Would love the larger size but still a bit nervous of the leather scratching. Haven’t used anything else since I bought it!
