Penguin 10 YF Sleeping Bag

With 900+ fill power down and roomy semi-rectangular shape, the Penguin 10 provides unmatched comfort and insulation to keep you warm when the frost hits the ground. Great as a single person bag when a bit more space is desired, or as a two person sleep system when combined with the Penguin groundsheet. Two draft tubes line the zipper to prevent loss of heat when used alone or with a Groundsheet. Optional hoods are available for cold weather comfort; these can be attached to the Penguin Groundsheet or zipped onto the sleeping bag when used by one sleeper.

YF: YFuse. Pertex Quantum® 20 denier mini-ripstop fabric treated with a DWR (durable water repellent) finish.

Love the penguin 10 nano Review by Colorado Craig
This is my second ff bag purchase. First was a 5 degree model on clearance back in the early 90’s. I still have it and use it 3-5 times a year in Colorado and the western US. Still has great loft and I’ve always loved the outer shell material. Durable. I bought the penguin together with the ground sheet and bag hoods. Again a top notch sleeping system, after one “season” its amazing for one, or two, in a variety of situations. I know I’ll enjoy it for decades to come. C (Posted on 1/27/2019)
Penguin and groundsheetReview by Jim & Catie
Over 10 years ago we bought the penguin bag and groundsheet, and had added down to make it a minus-10-degree-F rated sleeping bag. It has been wonderful, from desert to high mountains. We can open it when it is warm, and we are always warm when it is cold. Slipping into the bag on a cold night we get warm instantly. And of course sleeping together is the best. It never loses feathers as many down bags do. It has been worth every bit of the original cost, and has many years of service left. (Posted on 7/6/2018)
