Pretty certain that those are the same bag, and also that they are the same as the old TNF one I have. Someone just pumps them out with whatever logo you want. They do the job is all I can really say – pretty robust, basic, kit
Definitely different as I have looked at both in the shops. Main difference seems to be that the Eurohike has the thicker material all round, whilst the MW one has a ‘canvas’ base (which most of the more expensive ones seem to have too). I prefer the more discrete MW branding, but wonder if the Eurohike may be more robust.
I looked at the Decathlon one, and the others I mentioned seemed better. The LoweAlpine, I’d still only be getting a single bag for the cost of both of the ones I have mentioned.
