Sleeping Bag Ratings

It would appear that sleeping bag ratings can offer no consistency. Temperature ratings will still be determined entirely through the manufacturers within the bags. My 3-pound Sierra Designs bag, by way of example, was rated to twenty degrees. Honestly, it never kept me as warm as my 17-ounce Western Mountaineering sleeping bag, that could be only rated into 40 degrees. Isn't vid problem after you buying a bag? Any 45-degree bag will continue to keep you warmer rather than a 30-degree bag.

Consistent Sleeping Bag Ratings

Regardless of the temperature a bag is rated for, under any system of testing, it doesn't necessarily help keep you warm to it temperature. I not able to solve the situation of individuals having different metabolisms and bodies. A specific bag may well be beneficial to yourself right down to 20 degrees, while for the next it's just good to 40 degrees. You generally can work out an advanced cold maybe a warm sleeper, but of which does not help neighborhood retailer know whether a bag is rated excessively or lacking.

You should know if a bag says 30 degrees it will eventually help warmer than person that says 40 degrees. Repair, you will still add or subtract 10 or 20 degrees for use on your tastes, you are able to still discover which bag often is the warmer one. How should we have this consistency?

Begin testing with any sleeping bag, by placing a bag of water there that is certainly human-sized, weighing perhaps 160 pounds. Have three standard sizes for small, regular and enormous sleeping-bags. Always begin using the hot and cold levels at 100 degrees Fahrenheit, and measure the span of time before it drops to 90 degrees. External air temperature preferably should be particularly the identical too, whther it will be 60 degrees or 40.

The numbers aren't crucial. What's important at this point is that after the standards are chosen, every bag is tested the same, with the exact same conditions (even temperature and material for the testing platform might need to really do the same). This is just what offers consistency with the sleeping bag ratings for warmth.

Now, if the bag rated to 40 degrees keeps this type of water above 90 for 2 hours, a bag rated for 30 would obviously really have to it above 90 degrees a bit longer. Pegging heat-retention times to specific temperature ratings will be bit tricky first. However, once done, each new bag on the market will be listed in the testing and quickly given an even rating. We'd recognise that a lesser rating would always mean a warmer bag, degree-by-degree. We were able to get a hold of old bags tested to observe should it be enough time to replace them.

Manufacturer Acceptance?

Would manufacturers pay a non-public testing company to acquire their bags rated? Some, in the beginning, since the device might be a a bonus for people companies who're already conservative throughout their temperature ratings. We can have "proof" the bags are even warmer than that they were claiming. Then, eventually, all bag makers would feel some motivation to obtain their sleeping-bags tested, because consumers could well be wary about buying ones that weren't tested.

Lets hope someone can take this concept and gone with it. A present consumer rating company, like Consumer Reports, could use this ourselves and report the outcome. Despite that they listed the baggage without temperature ratings, in absolute order that held the warmth on the best, it becomes very handy. An online business browse through the list when their current bag kept them warm to 25 degrees, ythey know that any bag higher on the list may be warmer.
