 movement of the valve element. Since the control pressure is proportional to the drive force of the valve element if the control piston diameter is constant, it is possible to use the measured pressure value to determine the drive force required to move the valve element. If the drive force increases over the course of the operating time of the pneumatic valve, then this can be an indication of increasing wear. This invention relates to garments, especially combinations or suits of garments, and to easing the difficulty with which such garments can be fitted to the wearer. The invention is advantageous especially where the wearer is a child, and has to be helped into the garment, and especially where the wearer is a physically-disadvantaged child.
Although the invention may be applied to the design of other types of garments, the invention will be described herein mainly as it relates to wetsuits.
A wetsuit can be difficult even for a strong healthy wearer to put on. One of the difficulties with putting on a wetsuit lies in inserting the arms into the tubes that form the arm-sleeves, and in inserting the legs into the tubes that form the leg-sleeves. Even a non-disadvantaged person finds that it can take a good deal of muscular strength to force the hand and arm into and along the tight-fitting tube that comprises the sleeve. Also, the material from which wetsuits are made is generally foam rubber, which has a high coefficient of friction. The combination of tightness and high friction can leave even a normally-functioning person momentarily exhausted from the muscular effort of forcing the arms into the sleeves, and the legs into the pants, of a typical conventional wetsuit.
The therapeutic benefits of swimming are well known, and these benefits are no less applicable to disadvantaged children (and adults) than to normally-functioning persons. Indeed, swimming is often favoured, as being the activity in which a physical handicap is the least restrictive.
For a physically-disadvantaged person, especially a disadvantaged child, the effort needed to force the arms and legs into the sleeves and pants can be simply too much. Even with an adult caregiver assisting with the heavy pushing, it can be a major task for a disadvantaged child to get into a wetsuit. The task of getting a cold wet child out of a saturated wetsuit also carries its own difficulties.
The invention is aimed at providing a design of e.g. a wetsuit, in which
movement of the valve element. Since the control pressure is proportional to the drive power of the valve chemical element if the control piston diameter is constant, it is possible to practice the measured pressure value to determine the drive force out required to move the valve component. If the drive force increases over the class of the operating time of the pneumatic valve, then this can be an reading of increasing wear. This invention relates to garments, especially combinations or suits of garment, and to easing the difficulty with which such garments can be fit to the wearer. The invention is advantageous especially where the wearer is a child, and has to be serve into the garment, and especially where the wearer is a physically - deprived child. 
 Although the invention may be applied to the purpose of other types of garments, the invention will be report herein mainly as it relates to wetsuits. 
 A wetsuit can be difficult even for a strong healthy wearer to place on. One of the difficulties with putting on a wetsuit lies in inserting the arms into the tubes that form the arm - sleeves, and in inserting the stage into the tubes that form the stage - sleeves. Even a non - disadvantaged person finds that it can take a effective deal of muscular strength to force the bridge player and arm into and along the tight - fitting tube that comprises the sleeve. Also, the material from which wetsuits are make is generally foam rubber, which has a high coefficient of clash. The combination of tightness and gamey clash can exit even a normally - functioning person momentarily exhausted from the muscular effort of forcing the arms into the sleeves, and the leg into the pant, of a typical conventional wetsuit. 
 The curative benefits of swimming are well known, and these benefits are no less applicable to disadvantaged children (and adults) than to normally - function persons. Indeed, swimming is frequently favoured, as being the action in which a physical hindrance is the least restrictive. 
 For a physically - disadvantaged person, especially a disadvantaged child, the effort needed to coerce the arms and branch into the sleeves and pants can be simply besides much. Even with an adult health professional assisting with the heavy push, it can be a major task for a disadvantaged child to get into a wetsuit. The job of getting a cold wet child out of a saturated wetsuit besides carries its own difficulties.
