VKK-6D is a modification of the VKK-6M high altitude compensation suit. It's main (and only) difference is
the addition of the cable that connects suit's bladders with oxygen mask's altitude compensation system.
Please note, that since suit needs to be connected to the oxygen mask, VKK-6D should be worn with regular
helmets (ShL type leather and ZSh hard shell helmets) equipped with oxygen masks equipped with altitude
compensation system.
Front view of the VKK-6D suit, at first glance it looks exactly like VKK-6M. But note a thin cable
that connects suit's bladders and oxygen mask.
Waist area of the suit with suit's tubes. The one on the right is used to fill big rubber tubes that
run along the whole suit. The one in the middle (which points down on this picture) fills suit's waist
bladders. The last one (which points up) connects suit's waist area bladders with oxygen masks altitude
compensation system.
Suit's cable has a splitter on it's end which allows to connect both - helmet's occiptal bladder and
suit's bladders - to the oxygen mask's altitude compensation system.
Back view - here VKK-6D is similar to the regular VKK-6M suit..
