Per 
Special Containment Procedures: SCP 4371 requires no special containment procedures. SCP 4371 and SCP 4371-A are kept in a Foundation standard reinforced cardboard storage box (size C) in a standard containment locker secured with an electronic locking mechanism. Access is available with permission from onsite Level 4 researchers.
Description: SCP 4371 is a collection of eight plain red coloured tuques (also known as “watch caps”), SCP 4371-A is a water damaged instructional slip recovered along with SCP 4371. They are unadorned, adult one size fits all size, with only a manufacturer’s tag inside. They are made from a wool acrylic blend in an 80/15 ratio, with the remaining 5% being made of a previously unrecorded material identified as “NitroCon Fiber” according to the tag. The manufacturer is “The Gear Company LLC”. No such material or company has been identified as existing. The material itself is anomalous, being made from an unidentified organic material that has been treated with chemical compounds that cannot be replicated under non-anomalous lab conditions.
SCP 4371 remains in a dormant phase, even when worn, unless specific criteria have been met. To enter its active phase, SCP 4371 must be worn by someone who has, in the last 18 hours, been exposed to increased atmospheric pressure. This can be achieved by scuba diving to a depth in excess of 10.3 meters, time in a hyperbaric chamber, or work in similar environments (such as a caisson). At this point, if worn, SCP 4371 enters its active phase, and begins to convert excess nitrogen build up in the subject into alcohol. The anomalous process mimics decompression, but at a pace that greatly exceeds recognized safe decompression procedures as recognized by the US Navy, ADCI, DCBC, IMCA, or any known diving regulatory body. This alcohol is absorbed directly into the bloodstream, and, depending on the amount of time spent “at depth”/under increased atmospheric pressure, can result in what D-Class test subjects described as “a mild buzz” to immediate alcohol poisoning. The effect ends and SCP 4371 returns to its dormant phase when the subject wearing it has been “decompressed”.

Recovery Notes
SCP 4371 and SCP 4371-A were recovered aboard [DATA REDACTED], a commercial diving workboat based out of [DATA REDACTED], that had been recovered off the coast of Washington State by US Coast Guard assets after calling in a medical emergency. The USCG found that five divers aboard the workboat were suffering from severe alcohol poisoning with no evidence of consumed alcohol. Foundation agents with the USCG alerted nearby recovery teams when a USCG crewman who had been diving earlier that morning placed one of the recovered tuques on their head and immediately showed signs of alcohol consumption. Five instances of SCP 4371 were recovered from the workboat, and replaced with normal red tuques in USCG evidence storage by Foundation agents. Three of the divers died before reaching medical aid on shore, the surviving two divers, USCG diver, and workboat crew members were issued with Class A amnestics after it was confirmed that this was the first time they used SCP 4371.
Three additional instances of SCP 4371, and SCP 4371-A were recovered from [DATA REDACTED], the workshop and storefront the commercial dive team was based out of. Electronic forensic investigation revealed that SCP 4371 had been purchased by the commercial dive company as a method to undercut other contractors. The rationale being that they could dive longer and deeper, without having to purchase a surface decompression chamber. The owner of the company is missing and under investigation by civilian authorities.
