Updated for 2017, the Calder 600 is a 3 Fibreglass pole tunnel tent which comes with a pre-attached sun canopy providing a balance between living, sleeping and outdoor space when enjoying the summer weather. Our new and improved ventilation system featuring 50% larger vents, allow greater air circulation and significant reduction in the chance of condensation building up, making sure your tent stays fresh throughout your camping trips. The fully sewn-in groundsheet keeps you snug, while the patented Tension Band System (TBS II®) can be attached for added stability when needed.
