The Reinforced Dive Suit is a piece of Equipment that is crafted from heavily armored fibers. It cuts damage by 50%, increases heat resistance from 50° to 70° and deflects Tiger Plant spikes, whilst reducing swim speed by 0.95 m/s. It can be crafted using the Fabricator. The fragments can be found in Wrecks and around the Mountains.

The Reinforced Dive Suit consists of two items: the Reinforced Dive Suit and the Reinforced Gloves. The gloves are added to the inventory alongside the Reinforced Dive Suit when the suit is crafted. It must be placed in the body slot of the paperdoll UI to take effect. When not worn it takes up four spaces in the inventory.

The Reinforced Gloves along with its suit counterpart, take up four spaces in the inventory, and must be placed in the gloves slot of the paperdoll UI to function.

The suit's protection from heat up to 70° is still not enough to fully protect players getting close to lava in the Inactive Lava Zone and Active Lava Zone, where the temperatures can go to upwards of 90°.
