Coleman Coastline 3 Plus

The Coleman Coastline 3 Plus is a 3-person annex tent designed to expand your campsite setup with extra sleeping or storage space. It attaches easily to larger tents or RVs, offering a sheltered area for guests or gear without taking up much room when packed away.

Its outer tent is constructed from PU-coated polyester, which helps shed moisture, while the inner tent uses breathable polyester and No-See-Um Mesh to promote airflow and keep out even the smallest insects. The integrated polyethylene groundsheet forms a bathtub-style floor to block ground-level dampness, and the fiberglass poles provide a lightweight yet sturdy frame. Coleman includes pegs, guy lines, and a carry bag so you can get set up and pack down with minimal fuss.

The PU coating is a thin layer of polyurethane bonded to the fabric to seal its fibres and improve moisture resistance. No-See-Um Mesh is an ultra-fine screening material that prevents tiny bugs from entering the tent while still allowing air to circulate. A sewn-in groundsheet edge creates a continuous barrier against wet ground, helping keep the interior dry.
