This particular variation of power armor is much larger and bulkier than other recent portrayals, closer to the appearance of classic Fallout power armor. The set looks highly similar to the T-45d power armor, but with a few minor differences. The shoulders of the T-60 are composite, double layered, and shorter than its T-45d predecessor.
The T-45d shoulder plates are almost twice as long and are only a single piece of metal. The opening valve on the T-60 set is lower on the suit, larger, and has a slot for a fusion core. The breastplate on the T-60 has two vertical handlebars, while the T-45d has a single horizontal handlebar. This particular set is superior to T-45 and T-51 armors. [Source: wikia]
