Our colors determine the fabrics you choose on our site. We have nine 10D fabric colors and seven 20D fabric colors. No 10D colors looks exactly the same as any 20D colors, however we do have several that are close. Typically the 20D colors are lighter, where the 10D colors are darker, but have a shine to them. Many of the 10D options are somewhat see through and you can see the down within the baffles of the quilt. You will end up finding this helpful for when you need to redistribute your down. You will be able to see where the pockets of no down are in the baffles which will help you redistribute the down evenly. On the darker 10D colors, all you need to do is hold the sleep system up to the light and any problem areas will stand out.
Many customers like to use the colors of their sleeping gear as a tool in emergency situations. They will get a lighter color on one side of their sleep system to flag down help in an emergency, and darker colors on the other side to help dry their gear out when wet, this is mostly just a preference choice. However, if you are worried about dampness, then getting a darker color is a good idea.
The weather resistant stripes, though do have a functional purpose, also can be used just as a way to look even more awesome! Sure they help keep your footbox and top of your quilt dry from moisture while allowing more breathability in the center of your quilt. But they also allow you to add a 3rd color to your quilt. This could be helpful if you, as an example, want to show pride to your country and they use 3 colors in their flag. Or if you just can't decide between the Orange, Pink, and Yellow colors that we offer. Now you can get all three! Remember that in the end, the most important thing is that you not only have an awesome lightweight and functional piece of gear, but that it looks great to.
