For sale is this Burton Snowboards rucksack.
Designed with photographers in mind its main section is able to hold numerous lenses, flashes and other paraphernalia. Perfect for biking as well as skiing and boarding, I imagine this may of use to some of the top photographic talent that populates STW. The mini-sections you see in the second to final image are re-arrangeable depending on what you want to carry for the day. I seem to recollect paying a hundred or so for this, so it's for sale at £35. It's a had a very easy life and was probably more an aspirational than a practical purchase.
