I had the old green/grey one which I liked but was a bit small to hold a drink and sarnies for a full days fishing. Got the red/grey tri pack which is slightly better and bigger, holds a couple of pint alloy bottles in the side rod tube holders. Has capacity for a camal pack inside but not supplied. Some nice touches like the concealed magnets to hold forceps and clippers etc but is a bit bigger than the first green/grey one.
The new green one is out now,I got my tri pac off a lad who works in shop as he was getting the new colour. Better than a rucksack but not as mobile as a vest, depends what you need it for. If you try your "luck" you could get the old colour half price at your nearest store when new colour arrives
