Osprey Child Safety Products LLC of Cortez, Colo. is recalling about 31,000 backpacks for carrying children because a cut in the plastic buckle on the shoulder strap can cause the shoulder strap to release, posing a fall hazard to a child in the carrier.

The recall involves the Poco AG, Poco AG Plus and Poco AG Premium model child backpack carriers. These nylon carriers come in seaside blue, ivy green and black. They have a metal frame and a gray padded child’s seat inside. The back of the carrier also has an upper zippered pocket and a lower zipped compartment, along with a stretch pocket in the middle.

The production date code identifying when the carrier was manufactured is stamped on a black label sewn in the interior of the large lower zippered compartment in the back of the carrier. Recalled carriers have a production date code of S16SB03, S16SB04, S16SB05, S16SB06 or S16SB07. “Osprey” is printed on the back at the top of the carrier. The model name is printed on the back at the bottom.

Osprey has received no reports of injuries due to the issue, but is instructing consumers to immediately inspect the buckles on both straps of the carrier harness (pictured here) to determine if there is a cut in the plastic buckle on one or both straps. If the buckle is cut, consumers should immediately stop using the carrier and contact Osprey for a free replacement or full refund.

Consumers also may contact Osprey and return the carrier for inspection. If the buckle is cut, consumers will receive a replacement or full refund.

The carriers were imported from Vietnam and sold by REI and specialty outdoor retailers nationwide and online at amazon.com and rei.com from January 2016 through May 2016 for between $250 and $330.
