There has been some speculation around how much insulation is necessary for an over-system to perform it duty in managing internal condensation. Some have speculated that an Alpha over-system is not enough to perform, but this is absolutely un-true. The science of what is actually happening when using an over-system is rather complicated, with many

The down gear industry has not done a very good job of providing its consumers with valuable information regarding warmth comparisons. Sometimes it seems to me as if the industry has completely forgotten all of humanity’s previous efforts to quantify insulation, and started from scratch, as if we’ve never done it before. Wild and bizarre,

We’ve already established the definition of overstuff as density added to a base fill amount. Base fill amount is enough to just fill a volume. Density added to that is overstuff. However, one thing we should keep in mind is that this density is not in a rigid box. If that were the case, then

As a tiny shop, building everything from scratch, by hand, we have a very limited ability to supply our demand. If our first lottery is any indication, it appears we are supplying around 10 – 15% of people who are interested. It is really interesting to see the different reactions to this reality. I’d say
