The Ninth Layer Unisex Hoodie

Field gear for depths below authorized levels. This is the official Ninth Layer BSRI hoodie — the field crew design, the cave cross-section, the nine layers mapped and labeled with Layer 9 glowing at the bottom where the hum gets loudest. Warm enough for extended underground work. Durable enough for whatever you find down there. Authorized personnel only, but we're not checking credentials. Pendleton University isn't either, apparently.
