The online retailer, Campsaver, has started to manufacture and sell their own branded men’s and women’s mummy bags and hoodless sleeping bags, including the Campsaver Ultralight 30 Down Sleeping Bag, filled with 850 fill power goose down. Priced at just $299.95, it’s an excellent value (see table below) relative to other sleeping bags with the same amount of down insulation. Perhaps even more so because the 25.2 ounce Ultralight 30 Down Sleeping Bag includes higher end features such as a down filled draft collar, zipper guard, and draft tube that you normally only find on much more expensive bags.
The Campsaver 30 Ultralight 30 Down Sleeping Bag is a mummy bag with box baffles that keep the down in place so it doesn’t shift. It is cut wide at the shoulders with a girth of 60″ but narrow in the hips with a girth of 48″ to improve thermal efficiency. As a side sleeper, at least most of the time, I’ve still found the bag quite comfortable to sleep in and do not feel that my head is constrained by the wide and low mummy hood, making it easy to sleep on my back or side.
The Ultralight 30 has a draft collar that runs over the upper chest and around the back of your neck and shoulders. It is filled with goose down to seal the heat in the bag and prevent it from escaping when you move around at night. This is a feature commonly found on winter sleeping bags. (The draft collar is a bit hard to see in the photo above because the interior of the bag is grey, but it’s nice and beefy.)
Zipper Guard and Draft Tube
The Ultralight 30 has a fabric zipper guard that’s about an inch wide to prevent the zipper from snagging on the bag’s thin shell fabric. It runs along both sides of the zipper. There’s also draft tube filled with down that runs along the zipper and prevents warm air from leaking out through the zipper’s coils.
I wish more sleeping bags had zipper guards like this, especially with the lightweight shell fabrics which are being used by manufacturers today. If you snag a zipper on them, which is all too common, it’s way too easy to tear a hole in the fabric which will leak down, when you pull on the zipper to free it.
There’s a two-way zipper on the Ultralight 30, so you can vent the bag on warm nights but easily zip the bag up when it gets cooler late at night and before dawn. I like this feature because it extends the comfortable temperature range of the bag, giving you the option to treat it more like a quilt or blanket in summer.
The Campsaver Ultralight 30 Down Sleeping Bag has not been rated using the EN13537 sleeping bag standard unlike other brand name sleeping bags in its class. I think that’s a consumer requirement for three-season mummy bags, at least in my mind, and I hope Campsaver has the bags tested in the future.
When I asked Campsaver how they rated the Ultralight 30, they said that it has an equivalent amount of 850 fill power goose down to other manufacturer’s bags that have been tested using the EN13537 standard. That’s not a credible rationale anymore, given the effect that sleeping bag design can have on temperature rating, and doesn’t negate the need for cold room or standardized independent testing.
I can tell you however, that I’ve slept in the Ultralight 30 Sleeping Bag out on multiple 40 degree nights and have no doubt that it will be warm down to 30 degrees. Your metabolism or mileage may vary however…
Still, for purposes of comparison, I’ve listed several other 30 degree with 800-900 fill power goose down insulation to let you compare the amount of down fill they contain, their temperature ratings and measurements, and prices to give you a better feel for how the Ultralight 30 measures up to other sleeping bags which have been tested using the EN13537 sleeping bag temperature rating standard. The Campsaver Ultralight 30 is far less expensive than all of the other sleeping bags listed and nearly half the price of the most expensive ones, making it a good value alternative.
Most of the other bags listed contain down that’s been “waterproofed” in some way but not the Campsaver Ultralight 30, which is probably another reason it’s less expensive. While I don’t think waterproof down is a must-have feature for experienced backpackers, you may decide differently.
The Campsaver Ultralight 30 Down Sleeping Bag is a great three season mummy sleeping bag for budget-conscious backpackers who want a superior 850 fill power goose down sleeping bag loaded with excellent technical features. Weighing just 25 ounces, it includes temperature regulation features, such as a draft collar and two-way zipper, that make it adaptable to a wide range of cold or warm temperatures. While the Ultralight 30 sleeping bag’s temperature rating has not been validated by an independent product testing laboratory and its goose down has not been waterproofed like comparable name brand bags, I still think it’s an excellent value for the money and a good choice for three season camping or backpacking if you’re looking for a more affordable three-season down mummy bag.
