Sub School Pillowcase — Blackout Edition
For sailors who haven't seen the sun in 90 days.
The Sub School Pillowcase — Blackout Edition is a jet-black, total-opacity cotton pillowcase designed for submariners who have adapted to an environment where the sun is a concept and daylight is something that happens to other people. The fabric is 400-thread-count matte black, sewn in a standard queen size, and tested to achieve zero light transmission under laboratory conditions. Your rack is already dark. This makes the pillow match the assignment.
Sub school teaches a great many things: pressure hull theory, watchstanding, the sound of your own thoughts at 400 feet. One thing it does not teach is how to sleep in a room that has windows. This pillowcase is a transitional aid. It recreates the sensory environment of a submarine rack for the sailor who has returned to surface life and found the bedroom unacceptably bright at 1400 on a Tuesday.
The Air Force sleeps in hotels. Hotels have blackout curtains, pillow mints, and a front desk number. This pillowcase has none of those things. It has darkness, which is the only thing you actually need and the one thing the Air Force has outsourced.
“The Air Force sleeps in hotels with pillow mints and the curtains someone else hung, and they have made peace with that, and so have we.”

After-Action Reports
I have been on surface ships for two years since getting off subs. I still cannot sleep with light in the room. This pillowcase has fixed my marriage. Five stars. No notes.
Ordered six. One for every rack in my household. My civilian roommate asked why. I explained submarine sleep culture for approximately forty minutes. She uses one now too.
The pillowcase is too effective. I used it on a Saturday and did not wake up until the following morning. I missed a barbecue. The pillowcase felt no remorse.
