Most of us have got cold at some point while camping, but http://www.repairclinic.com/RepairHelp/Air-Conditioner-Repair-Help with knowledge and quality, weather-appropriate gear, it is entirely possible to sleep comfortably at 0 F and below using traditional insulating materials.
Beyond that, its a simple liner. The company doesnt specify the material used, but it appears to be polyester with a durable water repellent finish. Weve reached out to ask for more details and will update this post with responses.
For comparison, a Furnace 5down sleeping bag from The North Face rated for use down to 5F costs $239 retail for a regular length almost exactly the same as the future retail price of this liner.
Beyond that, it has similar traits as the Simple liner, but can be worn out of the bag and around camp, or as a long, cozy jacket for lounging around in hammocks or whatnot in cool weather.
The small pack will heat the bags from 2.25 hours (high setting, core and feet) to 15 hours(low setting, feet only), according to the company. The larger battery can run from4.5 hours (high setting, core and feet) to 30.4 hours (low setting, feet only).
We love to see the innovation here, but for now, well be sticking with our down bags.

The promise of a heated sleeping bag has launched a companys Kickstarter campaign into success, raising more than $100,000 in just a few days. Is an electric addition really the right way to warm up your cool-weather campout?

It sells for the same price as the Simple liner on Kickstarter.
Run Times, Battery Functions
The Ravean liners have removable battery packs that can also charge USB devices. They sell for $89 for a 7,800 maAh model, and $99 for the 15,500 maAh model.
The brand delivered on its promised heated down jackets, fulfilling its obligation to customers, and so far the reviews are pretty good. So, how will the heated liners pan out? So far, consumers are stoked.
Created by Ravean, a brand that made waves with a heated down jacket that raised more than $1 million last year, the heated sleeping bag liner is a next step in the brands evolution.
The liner, with a battery (which is not always included), sells for $179 early bird pricing ($200 regular) on Kickstarter, and the brand plans to sell them for $249 retail.
Wearable Liner
A second version is the Wearable liner. It is basically a very long jacket with heating elements running around the torso and feet. It has sleeves, pockets, and a hood.
Crawl into a sleeping bag. Push a button. Get warm.
Lets start with the simple liner, as its a basic bag that the Wearable model expands on. The liner has heating elements over two areas of the body the core and the feet. These are powered by a removable, rechargeable battery and controlled by a button system that can provide low, medium, or high levels of heating for each area independently.
The Ravean system appears marketed toward car campers or those who are looking for a leisurely weekend in cool weather. For this, it may be fine, but for those who rely on a sleeping bag for safety and comfort in remote areas far from a car, removing possible points of failure is critical.
Ravean says in its video (watch below) that the bags expand the range of your current, warmer-weather bag by 20 F. Thats a significant increase in warmth, but comes at a hefty cost.
While electronic heated garments and accessories have come a long ways in recent years, they still are not as fail-safe as good old-fashioned insulation.
With a promise to Sleep Naked Everywhere! something thats never been a problem for us in traditional sleeping bags were guessing this product is aimed at the novice or occasional camper. But the concept is interesting and worthy of investigation.
Ravean Heated Sleeping Bag Liner
The Liner comes in two designs, a simple mummy sack and a wearable design that looks like a mix of a sleeping bag and a jacket.
The battery is stored below the feet for this model. The liner has cinch straps for length adjustment, a full zipper, and it can be closed around the upper body.
Weve used lots of bags in this temperature rating, and while youll feel a chill as the temps drop to near 0, for sleeping in the teens or above, this or a similar bag should be cozy, and wont require batteries, wires, and regular charging.
Its unclear if other USB batteries can work with the bags, but Ravean says its new batteries are backwards compatible with its jackets, so these new batteries should work with the jackets if youve fully drunk the heated-garment Kool-Aid.
Does A Heated Liner Make Sense?
So, who really needs one of these heated liners?
The major job that returns most in resale value is an upscale replacement of siding using fiber-cement. The job costs an average of $13,287 but increases home value by $11,112, or 83.6%. A vinyl siding replacement returns 79.9% of costs.
http://money.cnn.com/2009/12/18/real_estate/return_on_renovations/
That was down a whopping 7.5 percentage points from their 70.7% return on investment in 2008 . At the height of the housing boom, in 2005, upscale kitchen renovations returned more than 80% of their costs.
In New England, where winter are long and cold, vinyl window replacements reap a better return than they do in the warm South Atlantic region, where poorly insulated windows don't mean as much expensive heat leaking away.
So, although replacement windows cost more in New England -- an average of $11,155 -- they add $9,152 to home values there, recouping 82.3% of their cost. In the South Atlantic states, they cost $9,705 but add just $7,417 to home values, 76.4% of their cost.
Ron Phipps, a real estate broker in Rhode Island, said how the house looks from the outside is more important than ever.
"A lot of the things that, historically, had huge value, don't have as much today," said Phipps. "If you want to redo a kitchen, it may no longer make as much sense to use upscale appliances -- Viking ranges, Sub-Zero refrigerator. Buyers may not pay any more than they would for a home with GE appliances instead."
Among the remodeling jobs faring the worst in return on investment were large, upscale kitchen remodels. They cost an average of $111,794 in 2009 and added $70,641 in recoupable value, just 63.2%.
"Once again, this year's report highlights the importance of a home's first impression," said NAR President Vicki Cox Golder, owner of Vicki L. Cox & Associates in Tucson, Ariz.
"It's kind of intriguing," said Phipps. "Buyers are using the unimproved houses to negotiate lower prices, but they wind up buying the remodeled homes."

Finishing a basement returns 84.4% of its $55,357 cost in the South Atlantic and only 64% of the $65,715 New Englanders spend for the job.
The most financially successful jobs are smaller-scale, lower-cost renovations that improve the exterior appearance of homes. In this down real estate market, curb appeal is king.
Biggest pay-offs
Adding a basement bedroom is also fairly cost effective, averaging $49,346 but adding $40,992 in value, an 83.1% return.
The return on investment for some jobs varies greatly by region.
One common renovation, a mid-priced bath remodel, for example, runs an average of $16,142 and adds only $11,454 to the resale value of a house -- recouping just 71% of its cost. In 2008, the same job cost less -- $15,899 -- and typically added $11,857 to the home's value, recouping 74.6%.
"If you're driving down the street and the house doesn't have great appeal, it doesn't matter how nice it is inside," he said.
So, if there are two similar houses in the area, buyers will use the listing price of the one that has not gone through a metamorphosis to get the seller of the renovated house to slash their price. Buyers http://www.sg-aircon-service.com/ want to pay for the caterpillar but get the butterfly.
But here's the kicker: Clients are savvier than ever in their shopping. Even though the costs of home improvements are less likely to be returned on resale than they have been in prior years, sellers may still have to bite the bullet and do the remodeling if they want their house to sell at all, he said.

NEW YORK (CNNMoney.com) -- Home remodelers are getting less bang for their bucks. For the fourth straight year, renovation jobs have added less to resale values relative to their costs, according to an annual Remodeling Cost vs. Value Report released this week by the National Association of Realtors.
Seller must play along if they want to make deals. "You get to sell the house more quickly if you do the renovations," Phipps said.
Of course, most remodeling jobs are done to please homeowners. Any increase in home value is a bonus, not an end in itself. But for anyone thinking of selling in the near term, keeping an eye on the bottom line is always a good idea.
On the other hand, buyers in the South Atlantic seem to reward sellers for adding living space more than they do in New England. Maybe thrifty Yankees hate having to heat those extra rooms.
The average remodeling job cost $50,908 in 2009 and added $32,497 to the value of the home, a ratio of 63.8%. That was down from a cost-to-value ratio of 67.3% in 2008, when the average was $49,866 and the added value was $33,568.
"Increasing livable square footage with a new deck or an attic bedroom is usually more valuable than just remodeling existing space," Phipps said.
