The Aire Tributary Sawtooth II Inflatable Kayak is a perfect craft for paddling on lakes, bays and easy rivers. Introduced due to the popularity of the single version, the Sawtooth II includes two seats that can be repositioned. The second seat can be removed entirely to make room for more gear on those long trips. Paddling a straight course is simple with the removable skeg and ribbed floor chambers. The Airecell system improves performance and durability using 1670 denier base PVC coated fabric to decrease the chance of tears.
