From Halopedia, the Halo wiki
The Volant helmet arrived in Halo Infinite, during Season 02: Lone Wolves, and was available through the season's battle pass at level 31. Based on the GEN2 Air Assault helmet seen in Halo 4, and Halo 5: Guardians, Volant appeared only as a helmet, with it and its attachments being available for multiplayer Spartan armor customization on the Mark VII armor core.
Volant features one exclusive attachment, the HUL-I/RS(X)/HEMLOCK. The HEMLOCK attachment is available through the free unlock track at level 51 in the Lone Wolves battle pass.
