LONG TERM FILL POWER?
Down processing technology has increased in sophistication
over the last decade allowing processes that can increase the fill power
of cheaper down. This gives you the customer a budget bag with a seemingly
expensive fill rating. The problem is that this bag will soon lose this
added loft, leaving you with a lacklustre and disappointing sleeping
bag. I know two sponsored climbers who recently found themselves stuck
together high on a mountain in sleeping bags of apparent equal weight
and fill. One bag was made in the UK and lofted so well it looked as
if the occupant had a bad case of gas, while the other 'top' range bag
made in the Far East resembled an old sock.
The lesson is that if you want the best then buy premier bags from
the companies that have a good reputation and steer clear of the meat
and gravy 'festival' and car camping bags manufacturers making bags
by the tens of thousands. Remember a good bag shouldn't be cheap, as
there are no real bargains in this high quality market, but good down
will take a lifetime's abuse, dry cleaning and stuffing.
