great bag

I am using this as a backpack liner (35L ) for my next hiking trip. I've yet to use it in the field, but it's super lightweight, though fabric is thin, it seems robust (bag recommended to use inside backpack) and I think it will be perfect to use as both organiser and as a waterproof layer between my clothes and the backpack :-)
