The Big Agnes Deer Park 30 Degree Sleeping Bag works well for the extra-large backpacker who can't find a bag that fits or the car camper who wants extra room and the luxurious comfort of 650 goose down.



The Big Agnes Deer Park 30 Degree Sleeping Bag works well for the extra-large backpacker, with a chest size up to 56 inches, who can't find a bag that fits or the car camper who wants extra room and the luxurious comfort of 650 goose down.

Appreciated by bigger backpackers that need more room and are tired of using bulky, cumbersome car camping bags that weigh too much to carry in a pack, the Deer Park offers a solution to this dilemma. While it isn't going to pack down to the size of a Nerf ball, with compression straps the Deer Park can be squeezed down to an acceptable 9 in. x 8.5 in. and weighs in at 3 lbs 4oz.

But, big backpackers aren't the only folks who will appreciate the Deer Park's features. The reason the Deer Park is so light and compressible is its 650 down fill. This luxuriously soft insulation combined with the generous semi-rectangular cut and the Big Agnes sleep-system make the Deer Park incredibly comfortable for a great night's sleep.

Insotect Flow technology is used in the Deer Park 30 Degree to help eliminate cold spots, regulate the movement of down inside the baffles and offer better body heat distribution. Strategically placed Flow Gate construction eliminates lateral and vertical down shifting by using vertical chambers with Flow Gates to control the position and density of the down insulation.

Big Agnes bags are not your traditional sleeping bags. Thanks to the Big Agnes System, Big Agnes bags are roomier and more comfortable than regular bags.

In a traditional sleeping system, the bag lies on top of a sleeping pad. In this configuration, many people find themselves rolling off the pad at night. Plus, the insulation on the bottom of the bag is compressed by the sleeper's weight. Once compressed, the fill loses the ability to insulate.

The Big Agnes System is different. Big Agnes joins the bag and pad together. The pad supplies the bottom insulation while the top 2/3 of the bag is insulated like a traditional sleeping bag. This design provides a secure foundation so you stay on the pad all night. You can roll freely, move into a fetal position, twist and turn without ever rolling off your pad. It also prevents the bag from twisting and engulfing you in an uncomfortable mess. Big Agnes uses this concept throughout their entire line of sleeping bags.

The Deer Park 30 Degree is designed to be used with the Big Agnes 25" wide rectangular sleeping pads. However, other branded pads with the correct dimensions (25" x 78") will also work.

Big Agnes bags weigh less and have more leg room than other comparable bags, which makes them more comfortable. They also pack down smaller and have much more room to stretch out. Sleeping in the Big Agnes System is like sleeping in a bed with the mattress under you for comfort and the covers for insulation.

Available in your choice of left or right side zipper, the Big Agnes Deer Park 30 Degree sleeping bag comes in a single, long length (78"). A nylon stuff sack and a cotton storage sack are included.

Likes: Overall just a fantastic product, great sleep system. Insulated sleeping pad slides into the bottom pocket. I'm a side and stomach sleeper. I move around constantly at night. With this bag I don't get tangled up or fall off my pad. Best sleep ever camping in this system. I'm 6'2, 215 and I've got lots of room. Used this a few times now and it's kept me warm when temps dipped down into the low 40's. Little big and heavy for back packing, but manageable. With some straps and a little effort this bag will pack down to a descent size. Section hiking the AT in the fall and this bag will be coming with me.

Dislikes: Here's the downfall of this bag. Haven't used this in the rain and that will be a problem. Backpacking, I use a 1 man solo tent. To get the pad into the pocket you really have to do it outside and then put the system into the tent. Solo tent is too small to do this inside the tent. If it's raining this set up process is going to get tricky and most likely things are getting wet. Worse case in the rain, bag will have to lay on top of the pad.

Likes: I tested this with an overnight low of 37 degrees. I slept in a T-shirt and shorts with socks and a beanie cap and was comfortable and warm.
I am a slde sleeper, and a tosser turner. I am 6'4" and 250 lbs. The Big Agnes sleep system that integrates most any camp pad is awesome, and the Park series is 5" wider so you have plenty of room to turn on your side. The chest girth of this bag is about 86" (which is about 20" more than many mummy bags). I have 10 bags and this one packs down smaller than all of the rest.

Dislikes: The integrated pad takes a bit of getting used to. If you turn over with your bag (the bag turns with you), this bag does not turn over because the pad is inside the bottom liner, so it's more like a bed, which is a good thing, but it's a bit strange at first.

Likes: This bag is light and has pleanty of room for bigger people. I was able to move around in it well, and was very comfortable,

Dislikes: I think the tempature rating is a little off. I used this bag twice now, with over night temperatures 30-40 degres and I was a little cold. I had to use extra sleeping wear and socks to say warm.
