OASIS by Gregarious Simulation Systems (GSS) 2025 Vintage Men’s Hoodie

---

The OASIS (Ontologically Anthropocentric Sensory Immersive Simulation) is an MMOSG (massively multiplayer online simulation game) created by James Halliday and Ogden Morrow of Gregarious Simulation Systems (GSS). While starting as an online gaming platform, the OASIS gradually evolved into a globally networked virtual reality world that most of humanity now uses on a daily basis. It will go live on December 8th, 2025, and will co-evolutionize the entirety of gaming and made up for all of GSS’s 10-or-so years of lost revenue they spent creating it. The unprecedented success of the OASIS made Halliday one of the wealthiest people in the world. After Halliday’s death, the OASIS continued to evolve and grow in popularity, protected from takeover attempts and legal challenges by the ironclad terms of Halliday’s will and the army of lawyers he had tasked with administering his estate.

Like all our designs, this one is treated with our signature ‘relic-ing’ process which includes our own secret recipe of hand-painted chipping, cracking, fading, and just the right touch of yellowing to ensure that it looks the part of a true vintage imprint.** We lay these works of art down on super-soft Gildan 18500 hoodies via state of the art direct to garment (DTG) printing which allows us to create a vintage effect that simply can’t be accomplished with other printing methods. With a large front pouch pocket and drawstrings in a matching color, this hoodie is soft, stylish, and a perfect mid-weight for laying in cooler weather or keeping the chill off during summer nights at the beach.

Not sure what size is your best fit? We recommend taking one of your current sweatshirts, laying it flat, and measuring it. The measurements in the chart below are taken with the hoodie laying on a flat surface. To get the length, measure from the high shoulder point down to the bottom of the sweatshirt. To get the width, measure approximately 1-inch below the armhole, across the chest, from seam to seam.

 

While our sweatshirts are made using premium, preshrunk cotton/poly blends, there can be some slight shrinkage depending on your personal wash and dry cycles. With that said, if you’re on the fence or just want to be able to layer over various shirts, we always suggest going up a size as hoodies are meant to be a little on the big side 😎

All sizes are provided in inches!
