NRS Inc. of Moscow, ID is recalling about 3,300 of its Chaos Side Cut whitewater paddling helmets because the rivets holding the chin strap to the helmet can fail and cause the helmet to fall off in an incident posing a risk to head injury.

NRS has received four reports of the helmet’s rivets failing. No injuries have been reported, but the company is asking consumers to immediately stop using the recalled helmets and return to the place where they purchased them or to NRS directly for a free replacement helmet or full refund.

The helmets, one of which is shown at right, were sold at Collinsville Canoe & Kayak Store, NRS, Outdoorplay, REI and other paddlesports equipment stores nationwide and online at nrs.com and aire.com from April 2014 through July 2014 for about $60.

This recall involves NRS “Chaos Side Cut” helmets used for water sports, including rafting, kayaking, stand-up paddling and canoeing. The helmet’s hard shell is available in yellow, red, blue or white. “NRS” is printed on the front and back of the helmet.  The recalled helmets have a black “Boa” dial-fit retention harness inside at the back of the helmet. “Boa” is printed on the dial. “Chaos” and PO#39225 are printed on a white sticker inside of the helmet. Helmets with an “Inspected” sticker inside the shell under the Boa dial are not included in this recall.
