I have been going through my older gear. I have 4 dry bag backpacks that I am not going to use. These would be good for outfitting the personal gear of a larger group. (better than plastic bags and the price is right). They have been used but not abused. No leaks. The yellow ones are Cascade Designs (31x16x8). The red is an early model NRS Bill's Bag HD (107 L). The green/black one is a Cabela Boundary Waters Pack that has never been used (31x16x10). I'll sell them all for $80 and you pay shipping. Send me an email if interested.
