Last week we talked all about the different types of down: duck, goose and new waterproof down. But this new waterproof down is not fool proof, if you get soaked those feathers might dry faster but until then you will be cold. So what is an adventurer to do if rain is in the forecast?
There are many types of synthetic insulation available in clothing and sleeping bags. As of yet, no one has matched down, it is still the most light and warm fiber out there. Synthetic manufactures like Primaloft are close, and working every year to reduce the weight of their fibers. So when should you choose synthetics over down?
