What makes this Discarrier bag special, is the fact that it is the biggest bag out there. It has space for two large drink holders, an outer zippered pocket for your mobile phone or MP3 player and two large compartments for extra storage (lunch etc). These two extra compartments also provide extra internal pockets for your personal items. It also has a hidden inner pocket when you think you might need that.
The Discarrier can accomodate the backsaver straps, although they are not included in the price. Off course it is fully water resistant and has a padded adjustable carrying strap.
To summarise: the most complete bag out there, you will never need another bag. This bag is available in colors blue/green, black/ green or red/green.
