There are some things that should be mandatory when camping and we think a good pair of down slippers is one of those things. Down slippers, tent mules? Whatever you choose to call them they provide nothing less than camping contentment and comfort after a long day outdoors. These examples from North Face and Nordisk will keep feet toastie and warm whatever the conditions with a choice of super lightweight synthetic or duck down insulation depending on which brand you choose. If that wasn't reason enough, and we think it is, then consider how practical they are in that they weigh very little and can be packed down to virtually no size at all.
