It’s always been very obvious to me, why using total fill weight, spread into an unknown area, can’t be an effective comparison metric. Over the years, there have been hundreds of examples of people being led astray by it, and this continually backs up my position on it. However, to anyone who isn’t constantly exposed […]
As we head towards autumn here in the NEUS, the first few cool nights are often a bit of a shock. After our bodies spent the hot summer adapting to staying cool in warm weather, they are ill equipped to conserve warmth in cool weather. It always highlights, to me, how much the perception of […]
Fill density in sewn through items is a balance between calculated loft and chamber width. As standard, our sweater fill density is optimized for static use, trying to maximize the warmth to weight ratio. There are cases where down garments get flexed into semi-active use where a higher density might be ideal. Examples might be […]
The short term exposure test is something I’ve done hundreds of times and the results were not surprising at all to me. It was more to provide a visual representation, instead of me just stating things. This long term test is something I haven’t specifically done, in this exact way, and the results were […]
https://youtu.be/kf2mO0ivGDQ There is a click bait video circulating right now that makes some bold claims about down being hydrophobic. I think most people with ample experience with down stuff can see through this sort of misleading information, but it uses some real shock value testing that catches people who maybe don’t quite […]
Nowadays, with the tools we have available to us, it seems super obvious that using total fill weight to assess warmth of down items is highly inaccurate. So why do we do it? Like most things like this, I think it was born out of a different time when maybe it made more sense than […]
I often see questions around sizing that sound like this…..” Is it true to size? ” or ” Does it fit big or small? “. I struggle with how to answer these questions because, technically, there is no way to answer them. There is no real ” standard ” size template that everyone must follow. […]
My perspective and intention with regards to life outdoors is that comfort and performance should be a combination of well designed gear and human adaptation. That adaptation should be both physical and intentional. In modern society we are continually pushed towards technology that is designed to do all the work for a negligent user. I […]
I ended up posting these as regular pages on the site instead of here in the blog so here are the links! https://timmermade.com/technology/total-fill-weight-explained-with-visuals/ https://timmermade.com/technology/calculated-loft-explained-with-visuals/
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 […]
