The Ortlieb medium weight PD350 dry bag is probably the best drybag in the world! It is tough and incredibly durable yet light enough to use practically everywhere. Originally designed for water sports the Ortlieb drybag has become the choice of all outdoor enthusiasts who want to keep their kit dry and clean. The roll top closure whilst not guaranteed 100% waterproof does meet IP64 standards which describes the bag as “Dust proof, no penetration of dust and protected against splash water coming from all directions”. Once the top is rolled it is secured with a tough buckle and there are two d-rings for additional security or locking. The base features a loop for fixing or holding and it is reinforced with PD620 fabric for increased stability and abrasion resistance.
