Why Wiggy's Temperature Ratings Are Conservative

TEMPERATURE RATINGS

The Temperature Rating Is Conservative

Just took this bag out on a camping trip during a freeze advisory where the temperature dropped to 27° F (cold for North Carolina in April). I was hot in this bag wearing Wiggy's Insulated Head Cover and a very light athletic shirt and pair of pants. Based on this trip I'm sure the bag would be comfortable far below the 20° F rating. Can't wait to test it out in winter while wearing a true base layer.

Alex thank you for your comment about the temperature rating of the sleeping bag you purchased.

When I first made the sleeping bags that became the Ultra- Light [plus 20 degrees], Super Light [zero degrees] and Ultima Thule [minus 20 degrees] I knew that I was under rating them so long as the user used them as I presented. Using them in a tent and on a ground pad. If one used them under the stars the temperature ratings were basically voided.

Yes, they may work okay under the stars for some but not for most. You see when the air moves across the bag it takes the heat with it. In a tent there is no air movement.

Over the years of making the sleeping bags as we do at Wiggy’s we have learned from our customers that the temperature ratings are conservative. That said I could have done one of two things, reduced the amount of Lamilite used in each bag or just lowered the temperature rating of each model. That is something I never thought of doing. I like being told that the Wiggy bags work below the advertised ratings.
