The Mega Light is one of the lightest four season, four person tents on the market. This floorless tent uses a single ultralight carbon fiber center pole for support and includes adapters to use a pair of trekking or ski poles in place of the included carbon fiber support pole. If you would rather not sleep on the bare ground, you can get the optional Mega Floor for just an additional 1lb 13oz, still incredibly light for a four season, four-person tent. Black diamond uses the durable, lightweight 30D SilNylon fabric on the Mega Light. This fabric is waterproof but will require seam sealing with Sil-Net, so we are including a free tube of Sil-Net with the Mega Light tent.
