Who camps in January, anyway?

The Big Agnes Deer Park Sleeping Bag is ready to bring comfortable three-season camping to the big and tall. Stuffed with 600-fill down to keep the weight and bulk to a minimum, this plus-size bag keeps the heat cranking from March through October. Before you turn in, slide your 25-inch-wide sleeping pad (sold separately) inside the Deer Park's pad sleeve and get ready to rest easy.

  • Big Agnes bags don't have ground insulation and are meant to be used with a sleeping pad (not included) to be completely insulated
  • Full-pad sleeve holds any 25-inch-wide sleeping pad and prevents you from rolling off your pad while sleeping
  • Soft, breathable, and down-proof lining feels great against your skin and features a stain-resistant finish in case the blister on your heel pops overnight
  • 600-Fill down insulation features a high warmth-to-weight ratio to save your shoulders during long days on trail
  • Flow insulation system with a unique baffle design distributes heat evenly through the bag to help eliminate cold spots, eliminate bulk, and keep weight down
  • Vertical baffle design prevents cold spots and degeneration of the lofty down insulation
  • Vertical Thermal channels enhance uniform distribution of heat over the entire length of the bag for greater warmth and fit
  • Semi-rectangular shape gives you more room to stretch out your tired legs
  • An insulated draft collar around your head and a draft tube covering the zipper provide extra protection to keep you toasty despite the cold
  • Built-in pillow pocket stows your puffy or fleece
  • Internal fabric loops allow you to add a sleeping bag liner during colder nights
  • Note: sleeping pad not included

Great bag, but a little light for 30degs

  • Gender:Male
  • Familiarity:I've used it once or twice and have initial impressions

I am stoked on this bag. I'm a big guy, 6'5" 210 lbs, and I have plenty of room in this bad boy. I recently took it on it's first trip and it fared pretty well, but I'd call it a 40 degree bag rather than a 30, because even in my medium weight long underwear I was still a little cold; not to the point of shivering, but just a little cold. If I could go back and do it again I'd spend the extra on the 15 degree, or I just might wear more layers when I sleep. Lucky for me it was a fluke that I hit weather that cold as I don't really plan on anything under 40. I had a 25" Therm-a-rest Trekker in it and I felt more heat coming from beneath me. I'm warmer in my 15 year old 20 degree Kelty, but that sucker weighs 6 lbs! However I'd still recommend it.


Great big bag!

Not the lightest in the world, but what a great way to get a large bag (zip two together!) for those shorter trips where weight isn't the absolute overriding concern.

Do 26" mats fit this bag

Yes the sleeve is extra roomy. I used a 26" wide exped in my park series bag all the time.

can you connect 2 together to make one?
