This is a useful sized first aid kit for out and about and comes with a well thought out set of contents which should suffice for its intended use.
I added a few more antiseptic wipes as it seemed a bit light on these, and a strip of paracetamol tablets.
It doesn't say in the description, but it does have a sturdy belt loop on the rear.
The only negative comment would be that I doubt the bag is waterproof, so if it was carried externally on a belt / rucsack strap it might be best to repack the contents inside a ziplock bag.
