Marmot Penguin -40 F Goose Down Winter Expedition Sleeping Bag – Vintage, Classic and Rare (yet still extremely functional)! This classic Marmot winter mountaineering bag is the real deal, made in the USA in Grand Junction, Colorado in the early days of Marmot, when they made things… You know, the way they just don’t make them anymore. It’s also the real deal in terms of its ability to keep a person alive on the side of an 8,000m peak at tens of degrees below zero, where this one served duty doing exactly that for my old man back in his crazy days. All baffles are still holding up strong and keeping the 800 fill power down where it should be, and our dedicated loose storage and regular fluffing and rotation routine over the years are evident in this bag’s unbelievablly high loft to this day – it’s as thick and fluffy as any bag out there. From my dad’s tales and my own research, I believe this is Marmot’s first super-subzero Gore-Tex/waterproof professional mountaineering bag. And I can absolutely attest to it being just as warm and effective as it was originally built to be, as it kept me very comfortable (and occasionally a tad TOO hot) during a pair of -25° nights in the Eastern Sierras some years ago. It’s also still very well sealed and waterproof from my own tests, despite some yellowing of the seam sealant. This is an absolute fortress of a winter down bag. The Penguin model is long retired from production, but the closest current equivalent is the Cwm, Marmot’s warmest and most “serious” winter bag. I’m unsure of the exact weight but I believe it’s between 4lb 8oz and right around 5lb. It is 82.5 inches long and generous in the hips and shoulders, which Marmot bags are known for. Here’s a great summary of all the things Marmot sleeping bags are loved for, if you’re unfamiliar. Includes its original stuff sack and a bonus loose storage bag, as pictured, so that you can store it properly and continue to keep that loft high and fluffy. Help me build a great reputation for the top-quality piece and the excellent service I provide to you in this sale!
