Sleeping Bag Ratings - A New Notion

De BISAWiki

It seems that sleeping bag ratings have no consistency. Temperature ratings are nevertheless determined completely by the producers of the bags. My 3-pound Sierra Designs bag, for example, was rated to 20 degrees. Honestly, it never kept me as warm as my 17-ounce Western Mountaineering sleeping bag, which is only rated down to 40 degrees. Is not this a difficulty when you get a bag? Maybe a 45-degree bag will keep you warmer than a 30-degree bag.

Constant Sleeping Bag Ratings

No matter what temperature a bag is rated for, under any system of testing, it won't necessarily maintain you warm to that temperature. Dig up supplementary info on this partner wiki by clicking web hard water filter. We can not resolve the difficulty of people getting distinct metabolisms and bodies. A specific bag may well be very good for one person down to 20 degrees, even though for an additional it is only excellent to 40 degrees. We found out about saltless water softener discussion by browsing Google Books. You generally can figure out if you are a cold or a warm sleeper, but that doesn't assist if you do not know whether or not a bag is rated also high or too low.

You need to have to know that if a bag says 30 degrees it will keep you warmer than one that says 40 degrees. With that, even if you add or subtract ten or 20 degrees for your private tastes, you can nevertheless figure out which bag is the warmer one particular. How do we get this consistency?

Commence testing with any sleeping bag, by placing a bag of water in it that is human-sized, weighing possibly 160 pounds. Have three regular sizes for little, normal and huge sleeping bags. Constantly start off with the water temperature at one hundred degrees Fahrenheit, and measure how lengthy just before it drops to 90 degrees. External air temperature has to often be the very same too, whther it is 60 degrees or 40.

The numbers are not crucial. What is important right here is that once the requirements are chosen, each bag is tested the exact same way, with the exact same conditions (even the temperature and material of the testing platform would have to be the same). This is what will give consistency to the sleeping bag ratings for warmth.

Now, if a bag rated to 40 degrees keeps the water above 90 for two hours, a bag rated for 30 would certainly have to preserve it above 90 degrees for a longer time. Pegging heat-retention instances to particular temperature ratings would be a bit tricky at 1st.

Manufacturer Acceptance?

Would suppliers pay a private testing organization to have their bags rated?

Then, ultimately, all bag makers would feel some motivation to have their sleeping bags tested, simply because consumers would be wary about buying ones that weren't tested.

I hope somebody will take this notion and run with it. An current consumer rating company, like Customer Reports, could do this on their personal and report the outcomes. Even if they listed the bags with no temperature ratings, but in absolute order by which held the heat in the finest, it would be really helpful. A single could look at the list and if their present bag kept them warm to 25 degrees, ythey would know that any bag larger on the list would be warmer. Isn't it time for steady sleeping bag ratings?.
