Our test protocol
A dozen testers participated in the test, especially during cold nights in the snow and in an igloo (with a floor insulation adapted – see our latest test of floor mattresses ).
We are two testers have slept several times in every sleeping bags. We systematically permutions bags during the night, so as to exchange our hot notice, and record them in a test report, with associated notes. All this information were then concatenated and depth.
We have also established an objective test protocol to assess the “heat” of all the sleeping bags, independent and repeatable manner, using a model “home” and two cans of hot water at about 75 ° C, one at the bust, the other in the foot (photo-cons ). This is the same calculation as for testing the freezer of our recent test of hot mountain gloves (a Pom’Potes playing the role of the can). Our protocol is explained in more detail in Carnets d’Aventures 33.
In CA No. 33 , you will find the results of this heat test (measured at the bust and feet), and the scoring of bags according to the following criteria:
- Thermal insulation quality (by construction)
- warmth / weight ratio
- Quality / price ratio
