Rating: rated 4.5 of 5 stars
Source: received it as a personal gift


This is a great sleeping bag for large men. I am 6'2" and 265 lbs and I toss and move in my sleep. The Hog Park allowed me to turn over in the bag while zippered.


  • Sleeve for your sleeping pad, so you can't roll off.
  • Large enough to be comfortable


  • Has no bottom insulation. Need to have an insulated pad
  • Has a sleeve for a pillow which I didn't need
  • Too heavy for backpacking

Ive used my Big Agnes Hog Park twice now. For me at 6'2" and 265 lbs it was great. the length was long enough for me to stretch out and its girth allowed me to turn over easily. I chose the Big Agnes Hog Park to go with my Big Agnes Air core pad that I have owned for 7 years (of course the pad chose to fail the first time I used them together. This just gave me the chance to upgrade to the Big Agnes Insulated air core.). The Big Agnes system is great. With the sleeping pad enclosed within the sleeping bag you wont ever wake up off the pad. 

The only drawbacks are the fact that you have to use a pad underneath because there is no insulation underneath. The other drawback is its weight at almost 6lbs.

Temperature Rating: 15 degree

First off I have to say that I absolutely love the concept of these Park Series bags from Big Agnes, and I think with a little work they would have a winner. They are extremely roomy, which is paramount for me as I just can't get comfy in a mummy bag, and the Summit Park is light enough to pack. But the 15 degree rating on this thing is WAY over rated.

I have now spent several nights in cold weather in this bag down to the mid 20's. Have tried multiple pads with this bag. Two inflatables and a Prolite 4. The last 2 nights with an Exped Synmat 9 Deluxe rated at R-6 and approx 0 degrees. With it, a full fleece liner and a layer of Capilene 4 I was just barely comfortable on cold ground surrounded by snow with temps about 25.

The down in the bag seems to work it's way towards the edges more than it should. BA says that they have corrected this with a different baffle design but I have the new design and it hasn't. There needs to be more down over the top of the body and not around the sides. Seems that in a race to produce the lightest that they gave up on comfort. I would gladly pack another 8 oz of down that stayed in place in this thing in exchange for comfort.

Oh, and the zipper ALWAYS gets hung up.

I have spoken with BA and they are great to work with, but even they suggested a liner or heavier insulated pad. Which I already have. They also gave me the name of a company that can do alterations and add more down. What would you bet they have had this complaint before.

These companies really should be held accountable for putting out these ratings hence the 2 stars. This is a 35 degree or better bag and if it would have been advertised as such, with a good zipper, it would be 5 stars. I am using this with equipment that is designed for colder weather. We should not have to go to extremes to make their rating work. There is only one other warmer pad that I am aware of and that is the Exped 9 Deluxe Downmat with an R-8 rating. I may get one, or I may just not camp in 25 degree weather any more.

Can someone please produce a true cold weather bag 0 degrees or so that is roomy, packable and comfortable?

Design: Rectangular
Fill: Quallofil
Temperature Rating: 20 degrees F
Price Paid: $55

I bought this in January for $55 for the bag and the Hinman sleeping pad from Sportsman's Warehouse on an inventory reduction sale. I have used it three times now. The coldest was 25 degrees F and I slept very warm. For car camping this is a great bag and as an older and more abused camper I found the thick sleeping pad very comfortable.
