          held up to international travel well

          Did a lot of searching for a good crossbody bag with anti-theft features before settling on this one. It worked very well for an international trip which included train travel, busy tourist spots and multiple cities. I didn’t test out the anti-slash (which would naturally require ruining the bag) but it felt sturdy. The zipper lock could be a bit cumbersome to undo but that is I believe the point. I especially liked the pocket that sits closest to the body as it wasn’t easily accessible (or pick-pocket attractive) but fairly easy to access.It easily fit a water bottle and/or small umbrella, epi-pen, passport in the main pocket with a credit card or cash in “hidden” pocket and a phone in the “outside” pocket. It was comfortable to wear either as a forward facing or backpack style. I went with the off-white which is something in the pale grey to off-white range of colors.

          So, so practical

          Bought this to carry my stuff while on vacation, so I used it every day for like a week. Love it. Very comfy, very practical. Will probably turn into my daily bag. It seems very well made and sturdy, like a really nice backpack.

          Not a good purchase

          The material is way too stiff and the snap does not stay shut on the outside. I would not recommend a purchase for this particular bag.

          Great medical bag

          I purchased the bag for my son in college. It's the perfect size to carry essentials on a day to day basis, including emergency medications all without being too bulky.

          bit smaller than expected

          I have not used the bag yet which is the reason for 3 stars but think it will work for a day bag on our cruise. Not quite as big as I expected. Would be hard to pack a rain jacket and bottle of water but we will see.
