Bed TimeWhen you require something to snuggle
down for the night in, what do you do? Do you buy a cheap polyester sleeping bag
or an expensive down one? Here are
some pointers to help you. What keeps you warm is the air, heated by
your body, trapped in the bag's filling – polyester-based (synthetic) or down
"feathers"). Polyester-based fillings are: ·
Hollofibre
- crimped (coiled) polyester with a hole through the middle; ·
Hollofil
- longer lengths of hollofibre, thereby reducing heat loss at the end of
strands; ·
Quallofil
- crimped polyester with four holes. There are various qualities of down used
as sleeping bag (and duvet) filling. Man has yet to improve on it for heat
retention. Whilst expensive to start
with, down will last a lot longer than synthetic materials, which tend to uncoil
with age. When packing a sleeping bag into its
stuff-sac, literally do just that - stuff it in!
Folding and rolling not only takes longer, but will eventually form
creases which result in cold-spots. |
