This is Harrison's views others see MCP suits as meeting the needs of future suits better than Hard Suits as they weight even more than traditional fabric "soft" suits. Those Gary Harris* in his history of spacesuits also favours a hard suit soft suit hybrid and dismisses MCP's for not having enough history and having yet to resolve the problems with fit, etc...

Space Suits and Extravehicular Activities

Extravehicular activities (EVAs) are strenuous and dangerous. Most
run four hours, and some have gone for eight hours. In addition to the
time spent on the EVA itself, there is time for preparation and wrap-
up, both of which are done inside the air lock. Outside the habitat,
moving even short distances is difficult when encumbered by a bulky
space suit. Relatively early in the development of spacecraft, handholds
were added to the exterior to make it easier for spacewalkers to scam-
per about. Later came small, personal propulsion units using tiny
rocket engines or compressed gas.

Space suit design is a fine art that requires resolving many dilem-
mas. Inspired by suits of armor and deep-sea diving attire, the space
suit must be strong enough to protect the occupant, but flexible enough
so that he or she can move around. An underinflated, soft space suit
is easy to move around in, but if too underinflated the suit will not
keep the person alive. Overinflating a space suit is in some ways safer
but makes it difficult for the occupant to move his or her arms or legs.
Having only a small faceplate makes it difficult to see what one is
doing, but since holes of any type are points of structural weakness,
having a large faceplate increases risk. The greater the number of joints
and movable parts the easier it is to move around, but the more op-
portunities there are for the space suit to develop leaks.
Despite preconceptions of space as a frigid void, dissipating heat is
the greater problem. The outside temperature may be well over a hun-
dred degrees. Inside the space suit, the hard-working spacefarer is giv-
ing off more heat. Not only is this uncomfortable and smelly but drip-
ping sweat and a foggy visor make it difficult to see, a situation that
cannot be remedied with a simple swipe of the hand. To help offset
this, spacefarers wear undergarments containing tiny tubes that have
cold water circulating within them.

Working within a space suit requires more time and energy (oxygen,
water, and food) and leads to much greater fatigue than working in
regular clothing. Operating equipment or conducting work that in-
volves intensive use of the hands and fingers fatigues even fit astronauts
in relatively short order. Early EVAs were tremendously exhausting
and caused spacefarers to sweat quarts of water, which they poured
out of their space suit boots after they squeezed themselves back inside
the spacecraft.

Designers seek lightweight, flexible suits for future missions.
Particularly desirable are increased flexibility for wrists, hands, and
fingers and feedback devices that give at least the illusion of touch. In
the future, hard space suits modeled after suits of armor will allow
occupants to work at normal rather than reduced atmospheric pres-
sure, without the "ballooning" characteristic of the soft space suits.
Shuttle space walks are related to specific tasks that are set in ad-
vance. They can be carefully planned and well rehearsed. On space
stations, space walks often have to be improvised as it becomes nec-
essary to make some sort of emergency repairs. The spacefarer may
not know what to expect until he or she exits the hatch. Furthermore,
moving from place to place can be extra dangerous on a space station
because the various antennas, solar panels, and experiment packages
have sharp corners and can obscure the view. It is not that difficult to
become disoriented, and more than one spacewalker has wondered
about finding the air lock to get back in.
