For those times when you are carrying everything you need for a week on your back or when check in airline baggage is tight - Patagonia have the answer, the Rio Azul Waders!

Patagonia's Rio Azul Waders are built for extreme lightweight performance and maximum packability, which also makes them a perfect fit for warmer weather and water. The supple H2No Performance Standard 4-layer, 6.1oz polyester fabric with waterproof/breathable barrier and a DWR (durable water repellent) finish is now put together with the same single seam construction for increased durability found throughout the rest of our wader line up.

Adding to the versatility of these waders, the fully adjustable suspenders have male and female buckles that allow quick conversion to a belt so the Rio Azuls can be neatly worn as pants. Patagonia's flat panel gravel guards drain water quickly if you fish in and out of a boat, in addition to better resisting abrasion and wear while hiking or wading.

Beneath the gravel guards, our improved booties have a more anatomical, sock like fit and are made from a denser 4mm neoprene that resists compaction better over the long haul.

A stretch wading belt with a low profile buckle protects you filling up with water, should you happen to go for a swim. Front utility keeper for convenient tool attachment. A raised Fitz Roy Trout logo tops it off.

Field repair kit included.
