... I have decided I need a new kit bag to trapse round the county with and I think I need a bigger than usual bag. ... Or had any other suggestions as to what the best bet is?
I bought a brand new North Face bag the other day - mainly for bike trips but I can easily see it being used for rugby as well. They are eye-wateringly expensive if you buy them in a shop, but you'd be surprised how many brand new ones are being sold on e-Bay by people planning long trips - but don't end up going. I bought it for 70% less than they sell for in the shops.
It's called the "Duffel" bag, but it's not what I remember duffel bags looking like when I was in school. It's a holdall but the straps are designed in such a way that it can be used as a rucksack if needed. I got the Large and it is big - in fact probably big enough to stick a kid in it. I did look at the X-Large as well, but that was too big.
