Better than I expected
I've purchased a number of sling / crossbody bags in the past year or so but often end up going back to a backpack for flexibility. Bags like Lulu lemon, Tomtoc etc., are all good bags but I find them too small at times and they can get bulky with only a few items in them.
The beauty of Red's cross body bag 7L is that if you only have a few items it rolls up small and lays nice and flat but if you want to throw in a small wind breaker or water bottle it easily expands to handle these items. It also attaches to a bike's handlebars quite nicely.
I purchased this for an upcoming trip to Paris and like that the roll down flap should make it harder for someone to pickpocket. Also there is a zippered pocket inside the bag to be extra safe for your key documents and a secure zippered pocket on the backside close to your body for items you want to keep safe but more easily accessible than having to open the bag i.e. smartphones.
I would like to see a better strap system as the strap it comes with is a bit on the thin side but still very usable.
