Plaintiff brought a products liability action after her husband drowned in an Oklahoma lake while wearing Defendants’ life-vest. The district court granted summary judgment for Defendants, and this appeal followed. We exercise jurisdiction under 28 U.S.C. § 1291.
The product at issue is a vest used in water sports, specifically waterskiing and wakeboarding. The vest was imported, distributed, and sold by Defendants. 1 Plaintiffs husband, Mr. Scott Wheeler, wore the vest while wakeboarding behind a boat driven by a friend. Mr. Wheeler, an advanced wakeboarder, attempted a difficult aerial trick, crashed face-first into the water, and was apparently knocked unconscious upon impact. Having observed the accident, the driver immediately turned the boat around and arrived at the would-be pick-up site within eight to ten seconds. The record is not clear on how long Mr. Wheeler floated at the surface of the water, but he had already sunk when the driver arrived. The driver, a certified life guard, dove into the water and attempted to recover Mr. Wheeler. Approximately two hours later, the Oklahoma City Fire Department located him drowned at the bottom of the lake.
Plaintiff, who witnessed the accident from lakeshore and assisted in the efforts to rescue her husband, brought this action under a strict liability theory alleging that the life vest was unreasonably dangerous. The district court granted Defendants’ joint motion for summary judgment, ruling that the vest was not unreasonably dangerous and that, in the alternative, Mr. Wheeler assumed the risks associated with using that type of vest.
Our review of the district court’s grant of summary judgment is de novo, applying the same legal standard as the district court.
See Simms v. Oklahoma ex rel. Dep’t of Mental Health & Substance Abuse Servs.,
Under the applicable Oklahoma product liability law, a plaintiff suing a retailer or supplier under a strict liability theory must prove (1) that the product caused plaintiffs injury; (2) that the defect existed in the product at the time of sale or at the time it left the retailer’s possession and control; and (3) that the defect made the product unreasonably dangerous.
See Kirkland v. General Motors Corp.,
In this case, Plaintiff asserts that the vest was defective in manufacture and also that the warning was inadequate. While there is some dispute whether she argued a design defect, we conclude that she has, and we address that argument separately. Plaintiff alleges two theories of manufacturing defect: (1) the thickness of the foam in Mr. Wheeler’s vest was only half of that advertised in promotional brochures; and (2) in a test administered by Defendants, five men wearing vests identical to Mr. Wheeler’s all floated at the surface of the water. Plaintiff also alleges that the vest was defective because it contained only 7.1 pounds of foam material and 10 pounds of flotation material is necessary to float an average person at the surface, which is a design defect argument. Finally, Plaintiff alleges that the warning attached to the vest was insufficient to apprise users that the vest would not float them in a manner necessary to prevent drowning. We turn first to the allegations of manufacturing defect.
A product is defective in manufacture if it “deviates in some material way from its design or performance standards. The issue is whether the product was rendered unsafe by an error in the manufacturing process.”
Jones by Jones v. Led-erle Labs.,
The record contains evidence that Mr. Wheeler’s vest contained 3/8-inch foam in contrast to Defendants’ promotional brochure, which advertised a vest consisting of 3/4-inch foam. Although we might expect advertised specifications to match production specifications, proving one does not prove the other. Plaintiff has been explicit that this is not a breach of warranty case.
See
Appellant’s Br. at 20. If it were, we would have reason to rely on the language of the advertisement, but it is not and we cannot.
See Osburn v. Bendix Home Sys., Inc.,
Plaintiff asserts that her husband’s vest must have been manufactured defectively because he sank. She compares this outcome to the tests administered by Defendants’ expert witness, where wearers did not sink. In those tests, males wearing vests identical to Mr. Wheeler’s floated at the surface of the water despite their best efforts to sink themselves. To establish a manufacturing
*758
defect under Oklahoma law, however, Plaintiff must “offer ... [a] theory as to the cause of the defect,” going beyond a mere “assertive statement that the defect occurred during the manufacturing.”
Kimbrell,
A product is defective in design if something about that design “renders it less safe than expected by the ordinary consumer.”
Lamke v. Futorian Corp.,
Plaintiffs final argument is that Defendants’ vest was unreasonably dangerous because the warning failed to apprize users that the vest would not float them in a manner necessary to prevent their drowning. A product is defective as a result of inadequate warning when “it is placed in the hands of the ultimate consumer without adequate warnings of the dangers involved in its use.”
McKee v. Moore,
CAUTION: READ BEFORE USE THIS PRODUCT IS NOT A COAST GUARD APPROVED LIFE SAVING DEVICE
This product is not approved by the U.S. Coast Guard, the Canadian Coast Guard or any other agency designated to grant such approvals and may therefore not be counted toward fulfillment of your mandatory carriage requirement. This product does not have any stated or *759 implied warranties concerning its performance.
This product is designed for use by experienced riders only. It should be used only during conditions where adequate supervision ensures constant monitoring of the wearer and pick-up boats are being used.
The buoyancy distribution is not sufficient to float a person face-up in the water. This product should not be used by non-swimmers and will not protect any wearers from drowning or injury.
THIS PRODUCT IS NOT A LIFE JACKET
Plaintiff explains that she and her husband had discussed this warning beforehand. They understood the warning to mean that the vest would not float a person face-up, such that they could continue to breathe even if unconscious, but that it would float a person face-down. Thus, when properly supervised, a downed wearer could be recovered by those in a pick-up boat. The district court noted that the label specifically warned of incapacity to float a person face-up in the water, but concluded that the warning “does not imply that it will float someone face-down in the water either.” Appellant’s App., vol. 2, at 385. We respectfully disagree with the district court. We see nothing in the label that warns a wearer that he or she will not float at all, which is a distinctly different risk than the risk of not floating face-up.
The warning uses the language “buoyancy distribution.” The implication, if not immediate connotation, of that language is that buoyancy is in fact distributed. Given the surrounding language, a reasonable wearer could understand that the vest has buoyancy distributed such that it will float a person face-down but not face-up. If the vest will not float a person on the surface of the water at all, the warning understates the risk because the issue is not merely buoyancy distribution but buoyancy deprivation. Further, the warning specifies that the vest should be used only when “adequate supervision ensures constant monitoring of the wearer and pick-up boats are being used.” Unless that language is superfluous, which construction we are inclined to avoid, the implication is that constant monitoring and the use of a pick-up boat will avail the wearer. If the vest will not float a wearer at all, supervision and pick-up boats are inadequate and rescue divers are necessary.
The district court observed that the vest is not Coast Guard approved, that it will not protect wearers from drowning, and that it is not a life jacket. A jury may agree with the district court that these general statements trump the specific warnings we have discussed, but that decision is one for the jury to make. Mr. and Mrs. Wheeler’s understanding — that the vest would not keep his head above water if knocked unconscious but would distribute buoyancy sufficient to keep him afloat and enable a pick-up to rescue him — is consistent with the language used throughout the warning. A reasonable jury could reach the same understanding and return a verdict in favor of Plaintiff. The warning did not alert Mr. Wheeler that he would not float at all, and sinking poses a distinctly different danger than not floating in a certain manner.
The district court articulated that Mr. Wheeler was an experienced wakeboarder who assumed the risk of drowning. The court identified the doctrine of assumption of risk as an alternative ground for summary judgment. Oklahama law requires a “voluntary assumption of the risk of a known defect.”
Kirkland,
*760 We conclude that there is a genuine issue of material fact about the adequacy of the warning. We REVERSE and REMAND for further proceedings consistent with this opinion.
Notes
. The vests were manufactured for Defendants in Asia.
