BP3-V3 Backpack

Pros.
Great bag. Lightweight.
Comfortable to carry and holds plenty of discs (I have 12 in the main pocket at the moment).
The dual water bottle carriers are a really welcomed addition. The fabric is waterproof (or resistant at the very least).
This bag is good value for money, I picked it up on sale for 30 odd quid which made it excellent value for money.

Cons.
The side pockets are relatively small, as is the main top pocket. This is not a problem for casual rounds or if you don't bring more than some snacks, your keys and maybe a foldable jacket. Would not recommend for tournament rounds necessarily if you like to pack lots of additional things. There is a towel hook but umbrellas are difficult to store.
One of the zip pulls has come off for me already, although this may well be down to me rather than the bag, but disappointing none the less.

On balance, an excellent bag that is good value for money. At the full price, there may be others that are comparable but I could definitely recommend this to someone who is just getting started or for casual rounds when a satchel bag is not enough.

This is a great bag. Fits plenty of discs, comes with dividers and has loads of pockets. I like that it has dual bottle holders.

My only wish is that it had a bit of structural support to it.

Been using this backpack for some weeks now and it's excellent. It has room for more than enough discs (face it, who needs more than 15 discs in a game...?), two drinking bottles and three extra rooms for whatever things and gadgets you might bring with you. Also very happy with it being water proof (especially the bottom of the backback) since the field we're playing in often has morning dew on it.

I purchased the blue version (not navy), I love the colour. The quality of product is great. Compartments are perfectly sized. YouTube how to build the insert that comes with it (it makes the bag more solid and allows to compartmentise the discs).
