I can’t answer your question “are we there yet?” since we are not, in fact, "there" yet. No one has tried out a new suit design on the Moon for a half century. It is certainly being worked on. Check the links below. The big design problem with pressure suits is change in volume with joint movement. If any volume change occurs, energy is needed (pressure x volume = work) to return to the neutral position. Two types of constant volume joints have traditionally been employed: Bearing Seals and Bellows. Below is the torso section of the Extravehicular Mobility Unit (EMU) suit which makes extensive use of bearing joints: [![enter image description here][1]][1] [![enter image description here][2]][2] https://ingeniumcanada.org/aviation/education/space-suit-hero-upper-torso-assembly The seals and bearings are complex, and a major source of suit leakage, even without moon dust gritting things up. [![enter image description here][3]][3] The alternative design is the bellows joint which allows flexion but not rotation. This elbow bellows is combined with bearing seals at each end to permit rotation.

Series: Materials Science and Engineering 187 (2017) 012014 doi:10.1088/1757-899X/187/1/012014 A bellows joint works on the same principle as a vacuum cleaner hose: Circumferential bands prevent change in diameter while soft sections in between allow flexion. A longitudinal restrainer is required to prevent internal pressure of an EVA suit from ballooning the length of the bellows. This restrainer defines the axis of permissible flexion. Bellow joints are very dust resistant. However, because they cannot rotate, they need to be paired with bearing seals. Without these constant-volume joints, suit pressure would immobilize the astronaut. Unfortunately, bearing joints (with their seals) are a necessary evil. With their tight tolerances and rubber seals, they are very susceptible to abrasion from regolith dust. And efforts to blow dust out risks driving it deeper into crevices.
