The exosuit protects the player from weather and other planet hazards. The exosuit includes a backpack that allows for storage of items and technology upgrades.
Upgrades will provide additional bonuses if similar technologies are grouped on the inventory page.
The exosuit has 3 separate inventories following the Atlas Rises update. General, Technology, and Cargo.
- General - maximum of 48 slots; each can hold 1 to 250 items
- Technology - maximum of 12 slots; reserved for Exosuit Technologies only
- Cargo - maximum of 25 slots; each slot holds 500 normal (eg. Iron) or 5 non-stackable items (eg. Gek Charm) like the starship inventory does.
- You can move items between General and Cargo by clicking on an item you want to move, then click on the other inventory category and click where you want to move to.
- You cannot sell items directly from your exosuit cargo inventory, it must be moved first. You can, however, craft items or recharge technology using resources stored in the cargo inventory.

The initial exosuit has 12 inventory slots and comes with the basic pre-installed following components:
The base inventory size of the exosuit backpack can be upgraded from 12 slots to a maximum total of 48 slots. Each upgrade station can be used once to increase the inventory size by one slot. The first upgrade is free, subsequent upgrades increase cost by 10000 units per upgrade. For example:
- 12 to 13 - free
- 22 to 23 - 100,000 units
- 32 to 33 - 200,000 units
- 42 to 43 - 300,000 units
- 47 to 48 - 350,000 units
If all upgrades are done using an upgrade station, the total cost to upgrade the exosuit to its maximum capacity will be 6.3 million units.
To upgrade the inventory the player may:
Cargo inventory slots can be purchased once your base inventory is at its maximum capacity of 48 slots. As of game version 1.32, you will only be able to unlock cargo slots after you've already maxed out your base inventory. Attempting to expand the cargo inventory when your base inventory is not maxed out will take your money, deactivate the upgrade station and give you nothing. Cargo inventory slots cost 50,000 units for the first slot; 100,000 units for the second slot; 150,000 units for the third slot and so on, up to 600,000 units at the 12th slot where the price is capped. To obtain n cargo slots, the cumulative cost is 25000*n^2 + 25000*n (up to slot 12, add on 600,000 units for every slot after that), so opening all 25 cargo slots will cost 11.7 million units in total.
The amount of time a player can spend underwater (and the maximum depth/pressure) are items that can be upgraded. Sean Murray has indicated that his character died in one game while trying to dive deeper than his suit would allow. "I found an ocean which was really deep, and my suit couldn't handle reaching the bottom. I could scan and see something was down there, but it was quite dark. I dived down and ended up drowning." 
Upgrades that allow this increase are Aeration Membrane Sigma, Aeration Membrane Tau, and Aeration Membrane Theta.
Like the player's starship, multi-tool, and exocraft the exosuit can be upgraded with technology.
* A bug in the "Install technology" panel list the "Coolant Network Theta" and " Toxin Suppressor Theta" as their "Tau" counterpart. But they are different.
