Request for Information on Combat Boot Sock

The Marine Corps is conducting a market‑research Sources Sought (RFI) to identify vendors capable of manufacturing a high‑performance, Berry‑Amendment‑compliant combat boot sock. The sock must meet stringent material composition (≥ 52 % wool, ≥ 20 % nylon, ≥ 1 % spandex), durability, compression, and shade‑matching requirements as detailed in Purchase Description MC‑PD‑24‑003. Respondents must submit their capability statement, business size, NAICS and CAGE codes, and evidence of a qualified domestic manufacturer. No contract is awarded at this stage; the RFI is used for future planning. • Over‑the‑calf, wool‑blend combat boot sock with graduated compression and non‑slip cuff. • Must comply with Berry Amendment (domestic production and fiber origin). • Required response by 5 p.m. EDT, 30 Oct 2026 to both government points of contact. • No samples or SAM registration required for this RFI, but will be needed for any subsequent solicitation.
