Cheap HQ Dry bags
 

Just bought some dry bags from here...

Excellent quality and strong materials and all at less than half the price of those found anywhere else. The 30L Overboard Grab Bag is an absolute steal at �13.00 and its ideal for the back of a bike with its yellow and reflective stripes. They're british made too! Always used Ortlieb before, not any more.

Highlander do a top waterproof bag, cheap and excellent quality - they supply the armed forces - lots of stuff on their website. Do a range of ponchos for those who are interested!
