The Vango Helium Carbon 100 is a technical, one-person tunnel tent designed for lightweight backpacking and thru-hiking. It features a semi-geodesic tunnel construction utilizing carbon fibre poles to provide a high strength-to-weight ratio. The design incorporates a single-pole configuration for rapid pitching and a side-entry vestibule for gear storage. The flysheet is constructed from Protex SH fabric with a high hydrostatic head, while the groundsheet is made from durable 70D polyester. The tent includes internal storage pockets and a side-access door, balancing interior space with a compact pack size.
