Described as "part legionnaire mail, part tactical body armor, and part chameleon", the SPI armor features [[photoreactive panel]]s that mimic the surrounding textures, effectively being the UNSC equivalent to the [[Covenant]]'s [[active camouflage]] systems.<ref>'''Halo: Ghosts of Onyx''', ''page 16''</ref> The SPI armor features a full body armor with an enclosed helmet and [[heads-up display]]. The undersuit is equipped with a cushioning layer of liquid nanocrystal that provides more ballistic protection than three centimeters of [[wikipedia:Kevlar|Kevlar]] diamond weave, without the bulk.<ref name="goo171">'''Halo: Ghosts of Onyx''', ''page 171''</ref> The hardened armor plates, though advanced compared to standard UNSC infantry armor, can take only a few glancing blows before failing.<ref name="goo14"/>

Though more advanced than the [[Orbital Drop Shock Troopers]]' [[ODST armor|body armor]], the SPI armor is less powerful than the [[Mjolnir armor]] originally issued to the [[Spartan-II]]s.<ref>'''[[Halo: Glasslands]]''', ''page 207''</ref> Its main benefit is that it is drastically cheaper to produce than Mjolnir.<ref name="goo46">'''Halo: Ghosts of Onyx''', ''page 46''</ref> It is also not as bulky or as heavy as the Mjolnir armor, making it easier to handle and transport.<ref>'''Halo: Glasslands''', ''page 40''</ref> The SPI suit does not significantly enhance the user's physical performance (i.e. strength, speed, agility),<ref>'''Halo: Last Light''', ''page 33'' (Google Play edition)</ref> and unlike Mjolnir, it can be worn by any individual and does not require special neurological, skeletal or muscular [[Biological augmentation|augmentation]]; for example, the unaugmented instructors for the Spartan-IIIs often wore SPI armor.<ref>'''Halo: Ghosts of Onyx''', ''pages 89, 94''</ref><ref name="g164"/> It is also made of a less durable, less dense alloy than Mjolnir armor: [[Kelly-087]] dented a Spartan-III's chest plate with her fist when first encountering the Spartan-IIIs.<ref name="goo168">'''Halo: Ghosts of Onyx''', ''pages 168-169''</ref>

The SPI armor generally lacks an [[energy shielding]] system, making the user far more vulnerable to enemy fire. However, the Spartan-III [[Headhunters]] wore experimental armor that was equipped with energy shields due to their elite nature and value. However, power must be drawn from the energy shields to recharge the suit's active camouflage module.<ref name="head212">'''[[Halo: Evolutions - Essential Tales of the Halo Universe]]''', "[[Headhunters]]", ''page 212''</ref>
