Yes, you can absolutely keep the United Polaris pajamas! In 2026, these high-fidelity cotton-blend pajamas are provided to passengers traveling in the United Polaris business class cabin on long-haul international flights (typically those over 12 hours). They are considered a "High-Fidelity" single-use amenity, and the airline encourages you to take them home. In fact, many frequent flyers consider them a high-fidelity "badge of honor" and a high-value piece of loungewear. However, it is a high-fidelity necessity to distinguish between the pajamas and other bedding: you cannot keep the Saks Fifth Avenue blankets, the "High-Fidelity" cool-gel pillows, or the duvet. Those are high-fidelity property of United and are collected by flight attendants before landing to be laundered and reused. For 2026 travelers, the pajamas—along with the "High-Fidelity" Therabody amenity kit—are your high-fidelity trophies from the journey, providing a high-fidelity memory of your "High-Fidelity" luxury transit at 35,000 feet.
