The ProLite Session Longboard boardbag is 5mm thick with reinforcement at nose and tail. The zip is set back from the tail of the board to improve protection further. There is a carry handle and adjustable shoulder strap which has a velcro stash pocket. Inside this pocket there is a further smaller one for wax, valuables etc. The shiny silver finish on the underside is essential on a boardbag, reflecting sunlight and heat, thus protecting your surfboard from delamination and also preventing your wax from melting. Heres a useful tip. Choose which way up you're going to keep your board in the bag and stick to it. By doing this your board will be much easier to remove from the bag on even the hottest days and you wont get wax on the underside of your shiny speed-stick!
