osprey 25l women's backpack Sportlite Lightweight Hiking for Men and Women, Blue Sky, S/M and there is a lower loop for a signaling light Osprey Sportlite™ 25 Hydration Backpack

For airline travel, it makes a nice personal item on top of hard-sided luggage

I like using it, but usually reserve it for either the lining of a bag (to add extra body), for straps (so that they are padded, but without any extra bulk), for small flaps, etc

If youre after a polished, professional look that doesnt compromise on practicality, then there are few brands better equipped to deliver

Top access makes it easy to grab items on the go, while the clamshell opening flips open like a suitcase when you arrive
