Item #: SCP-3397

Object Class: Safe

Special Containment Procedures: SCP-3397 is to be kept, folded, in standard storage in site-24. No tests may be conducted on SCP-3397 without approval by Dr.████

Description: SCP-3397 is a men’s large black zippered hoodie, with two buttoned chest pockets left and right of the zipper.No brand name has been found on SCP-3397 to see who might have made it. SCP-3397's body is 55% cotton and 45%polyester, the body/hood lining is faux fur 100% polyester, and it's sleeve lining is 100% polyester. When a sentient humanoid creature wears SCP-3397 on their torso1 in a way they might wear a non-anomalous hoodie, said creature enters a catatonic state, and SCP-3397 will physically and/or mentally alter the subject in some way depending on the subjects past or present, and depending on what is in the right or left chest pocket. Approximately 1.5 minutes after the subject activates SCP-3397, a high-frequency wave is emitted from SCP-3397, canceling all attempted external scans on SCP-3397, and the subject using it.Things put in the left chest pocket alter the subject to their benefit, and things put in the right chest pocket alter the subject in usually lethal ways. Given there is nothing in the chest pockets, there is no way to predict how beneficial the alteration might be. After 1-24 hrs, the subject will wake up and take off SCP-3397 as quickly as possible2. SCP-3397 seems incapable of being damaged by the effects of the alterations it creates.

Test 2

Subject:D-316847, Caucasian male with an aggressive disposition.
Chest pockets:Empty
Time:1 hour
Results:Subject doesn't wake up. Thermal scans indicate their blood had been super-heated to 158°C, searing them from the inside. It is currently unknown how D-316847's blood didn't boil when it hit 100°C, or how it never cooled down at all after SCP-3397 was taken off.

Within the first 3 hours, the sounds seemed to be that of car repair/ construction, including metallic clanks, a multitude of different clicks, and various power tools. During the next 3 hours, the sounds consisted of sounds that a 2016 Ford Transit Passenger would make, such as honks, engine noises, and various types of sputtering. during the last hour, all that could be heard from SCP-3397 was a quiet occasional click or clank. D-71458 never woke up, and an autopsy showed that their stomach was replaced with an unidentified automobile engine, and 89% of their other interior structure was pieces of metal and unidentified car parts.
