The YSHIELD® TSB Shielding Sleeping Bag offers a durable and portable alternative to traditional RF shielding bed canopies. Designed to attenuate high-frequency electromagnetic fields (RF/EMF), this groundable sleeping bag is made from Steel-Gray fabric, providing convenient shielding for use at home, while traveling, or in temporary sleeping environments.

The sleeping bag is made from 40% cotton, 30% polyester, and 30% stainless steel, offering a durable, wash-resistant construction. Measuring 90 × 220 cm (3.0 × 7.2 ft), its generous dimensions provide comfortable sleeping space for regular use.

The TSB features a silvered zipper for integrated shielding, a removable cotton inner lining secured with a hook-and-loop fastener, and an adjustable elastic head closure that can be tightened to leave only the face exposed. The cotton lining provides additional comfort against the Steel-Gray fabric’s slightly coarse texture.

With 42 dB shielding attenuation at 1 GHz and manufacturer testing across 600 MHz to 40 GHz, including 5G frequency ranges FR1 and FR2, the TSB Shielding Sleeping Bag provides a practical, reusable shielding solution for bedrooms, hotels, business trips, and other portable applications.
