For many years, I have know of the Kelty packs made of Spectra.
I finally bought one. This page is a collection of everything I can find
about the Kelty spectra packs. There are some files I have downloaded from
Kelty. There are some old web pages, saved by archive.org, and presented here.
Some old web pages are missing pictures. This is not an oversight on my part,
the pictures simply weren't saved by archive.org.
There are some pages from old catalogs that I have kept over the years. If
anyone has some info that isn't here, I would appreciate a copy if it to add
to the modest data presented here. I would really appreciate old
catalogs describing the Kelty Spectra packs. I put the catalog scans at the
bottom of the page, as they are a bit on the large side for some.

Cloud and Vapor Instructions @2000

WHITE PHANTOM
For those long (and often extreme) alpine trips. The lightest
and toughest expedition pack ever created. The insanely strong and
light Spectra fabric (pound for pound ten times stronger than
steel) and aircraft aluminum alloy stays laugh at heavy loads and
alpine abuse.

Additional horizontal rib stay to cup your back and
prevent pack roundout
CobraCut shoulder straps anatomically distribute the
load
Load lifter, side stabilizer, and sternum straps provide
stability and freedom
Conical waist belt distributes weight comfortably, but
doesn't get in the way of a harness
Packbag
Side pockets have ski slots behind them
Top pocket converts to a fanny pack
Two quick release ice axe holders positioned so you can
get your axe while wearing the pack
Clip loops on shoulder and belt straps
Dual ice tool holsters on lower sides can also carry
crevasse rescue gear
Rope lashing and compression straps

WHITE CLOUD
High alpine ascents and descents. The Cloud is lighter
and smaller in capacity than the Phantom. The same Spectra fabric
(pound for pound five times stronger than Kevlar) gives it the same
strength and durability. It's a perfect size for skiing trips and
super alpine ascents.
