Here are my versions of 2 advanced vacc suits (using MongTrav2 stats, see the CSC-2e for detail's about armor and vacc suit electronics suites).
The TL 14 vacc suit is the natural extension of the development of vacc suits. It is lighter and provides better protection against damage and radiation than previous models, but it is also a garment designed to only be worn in hostile environments. Without the helmet, it is almost light enough to be worn as clothing, but not comfortable for everyday shipboard wear.
TL 15 Tailored vacc suit represents a convergence of the vacc suit and the TL 10 pressure sleeve. The suit itself consists of a light, durable garment that can be worn as ordinary clothing and has a mass of 2 kg. It features detachable gloves and boots, integral temperature control, and contains a portion of the suit's integral electronics suite (Computer 3, Geiger counter, radio transceiver), as well as an integral environmental reader and a short-term life support system. The suit also possesses the self-sealing and smart fabric modifications. If the wearer's environment becomes hostile, the suit alerts the wearer to don their gloves and it deploys a flexible transparent bubble helmet from the collar. This combined with the integral rebreather provides life support for 30 minutes.
To gain access to the full electronics suite and longer term life support, the wearer must don the helmet (which contains the sensor suite) and the yoke, which contains the life support. The modifications chameleon IR & chameleon visilight apply to both the suit and the helmet and yoke, but the modifications extended life support, medikit, and thruster pack are all added to the yoke and cannot be used if the yoke it not worn. The yoke and helmet together has a mass of 2 kg and are not designed to be worn as part of everyday use.
