I've used it once or twice and have initial impressions
True to size

Really interesting bag, BD has put a lot of thought and care into this one it’s obvious. It weighs almost nothing, packs down into an attached stuff sack (brilliant idea as it’s so small it would get lost instantly) that is not bigger than a small mouse! Also has an adjustable sternum strap! Incredible attention to detail for such a featherweight minimalist bag. Should straps are adjustable too with a very clever system and they are cut wide . Suffice it to say a bag this ultra thin cannot be expected to carry heavy sharp objects, I have not used it yet, but for things like hats, gloves, socks etc or food and drink (or garbage) it seems perfect. My city is outlawing plastic bags so this should also come in handy to keep in a back pocket and use if need to buy basic groceries etc . I’m a bag collector this one impressed me for its careful design and build for sure
