The Hog Park 20 is a Synthetic filled sleeping bag incorporating the Big Agnes sleep System, geared for the big guys or those who want more space.

Big Agnes says:

Park Series Synthetic bags are cut tall and wide, ideal for campers of a larger stature, barrel-chested strong men, or for folks who just want more room to move around at night. Ideal for hunting camps, base camping, or road-tripping. Slip one of our 25” wide pads into these Big Agnes System bags, which utilize our full pad sleeve design. With double zippers and top corner hand pockets that feel just like your comforter at home, the Park bags’ unique quilt-like construction turns your bag into a backcountry bed. So comfortable,you won’t want to go home!

Compared to other Big Agnes sleeping bags, the Hog Park 20 is cut with extra length and a wide girth. It's so roomy that space and comfort are simply not an issue. This makes the bag ideal for taller, bulkier people or for those who just want more wriggle room.

The bag is constructed from a nylon taffeta shell fabric with a water repellent finish and has a cosy cotton polyester lining that feels a lot like your sheets in your own bed. The Thermolite Extra fill is a cosy insulating material that offers all the plush warmth and softness of down but with a lower price tag. Of course it is bulkier and less compact then down, but this isn't the type of bag you would take lightweight back packing. Comfort over weight is the key selling point here.

Like most Big Agnes bags, the Hog Park 20 features an integrated full pad sleeve so you can enclose your pad within the sleeve, creating a secure attachment to the bag. This is a great idea as when insulation material is compressed under your body, it loses most of it's ability to insulate. This will prevent that as well as preventing you sliding off your mat in the middle of the night.
