Backpack recommendations - big enough to put a helmet inside.

[Ben Diesel]

@b1k3rdude I have an 'as new' Knox biker rucksack that will take a full-face helmet - my Arai RX7 fits inside it. At a guess, I'd say 35 litre capacity.
Also, an Oxford Sports expanding tailpack.

I'm selling them to raise funds for British Heart Foundation in memory of a friend.

You can have either or both in return for a small donation and cost of postage.

Can supply photos if needed.
