Big Agnes Echo Park 40 (FireLine Max) Backpacking and Camping Sleeping Bag

Extremely cozy and warm. You feel luxurious while camping. Versatile with the pillow area attachment (you can just jam a sweatshirt in it to make a pillow) and the zippers help with heat control

This is a fantastic sleeping bag. It's warm and wide, which is great for back sleepers and curvy hips. It attaches to my sleeping pad and worked well!

I really love this bag. I'm a warm sleeper, but at 50 degrees I was sweating. The great thing about this is the ability to unzip both sides of the bag getting some ventilation and feeling like more of a "quilt" than a "bag". It packs down fairly small and is very comfortable.

Didn't get a chance to use it but looked very warm and comfortable. Unfortunately, the bag was full to the brim, so when I opened the box, it cut the sleeve bag that holds the sleeping bag itself, so be careful when you open the box! Had to return because the volume of the bag itself would not fit inside my backpack.

Large and in charge! Big Agnes is BIG. And, Warm (-20*) and comfortable. Many innovative features not available in other brands. I’m using it for a 5 year road trip through the USA. It will be in my motorhome and won’t be “moving”…IT IS NOT A LIGHTWEIGHT BAG.

I don't even know where to begin. This sleep system is incredible! It has the perks of a quilt without the draftiness. It stays fastened to your sleeping pad all night. It has a pocket for your pillow beneath the hood so that your pillow doesn't fall off your sleeping pad. It unzips on both sides so that you can always get out of your bed, no matter what direction you have to set it up. There is a draft collar for colder nights and zipper pockets for your phone or a flashlight. I have always hated, and I mean HATED sleeping bags. They wrap around me while I sleep, they are impossible to stretch out in, they slide of my sleeping pad or bunk mattress, and, worst of all, I get super claustrophobic to the point of panic. So this sleeping bag/sleep system is a game changer! I was able to move freely in my sleep, my pillow didn't go anywhere, I was warm, and the thing stayed on my sleeping pad! Oh, and the zippers didn't get caught. The set up took a moment for me to figure out but it's really easy to strap the bag to your sleeping pad. You just have to lay the bag out first, topside down, so that the straps are facing up. Then, put your inflated sleeping pad onto the sleeping bag and put the straps on. Tighten them as needed, and then you're set! It's honestly ridiculous how excited I am about this sleep system but it's a big deal for me, especially as a camp counselor (who has to sleep on a sleeping pad in a yurt for three weeks). It is absolutely worth the $200. It will last me for years to come and with a compression sack (sold separately) it packs down small enough to fit in my Kelty Nena women's 60 liter pack.

Getting ready for a never-ending around-the-world tour starting in May. Decided on the Big Agnes for a sleep system. Threw it on the bed. Climbed in. Uber comfy! Roomy! Keeps you WARM! Had to sleep on top with a sheet. Pitched my tent. Temp dropped to 36. Using a cheap 1.7 pad. Long sleeve T and PJ bottoms. Way warm. Only problem is, it's HUGE rolled up. Going to have to strap it on top of my rear bag. Other than that: worth the $$. Great bag.

This is a gem in 20 degree weather. The material on the inside is a game changer, it feels just like you bed. Big Agnes never disappoints me Update: 21 nights later and still going strong

**5-Star Review: Big Agnes Echo Park Sleeping Bag – Total Game Changer!** I can’t say enough good things about the Big Agnes Echo Park sleeping bag — it’s a total game changer for anyone who enjoys camping but hates tossing and turning all night in a cramped, cold bag. From the moment I climbed in, it felt like I brought my bed from home into the tent. The spacious design gives you room to move, turn, and stretch without feeling like you’re wrapped in a straightjacket. The fabric is soft and cozy, and the insulation keeps you warm even when the temperature drops. No more waking up freezing at 3 AM! What really makes it stand out is how much it improved the *entire* camping experience. If you’re on the fence, don’t be. The Echo Park is worth every penny. Whether you're a casual camper or out every weekend, this bag seriously changes the game.
