For guide-grade water protection, we like the NRS Heavy-Duty Outfitter Bag. This bad boy takes plenty of abuse with its burly PVC construction, and its large, 100-liter capacity carries more than its fair share of our paddling and camping gear for multi-day trips. It's our choice for big loads and big water-whether we're actually an outfitter or just a seasoned paddler looking for the best quality dry storage.
