Bathtub edge, not flat.
Raised perimeter edges keep groundwater and twigs from migrating up into the floor — even on a saturated pad after a night of rain.

FREQUENTLY ASKED
Questions, answered.
Will this fit other tents?
No. The hexagonal cut is sized only to the Gopamir G450 main canopy (450 × 380 cm). It will not fit the TN600 or T720+ models — those use different shapes.
Can I use it on gravel or rocky ground?
Yes, with care. Brand-approved for crushed-rock and gravel pads when sharp objects are cleared first. For longer life, lay an additional tarp underneath on abrasive ground.
How does it attach to the tent?
Square toggles clip into the G450's air-pole O-rings at the corners, and Velcro strips align with the three view doors. Setup takes about 2 minutes.
Is the material truly waterproof?
Yes. P300D polyester with a waterproof coating rated to a 10,000 mm hydrostatic head — well above the 3,000 mm rating on the G450 main canopy. The bathtub edges add a second water barrier.
Air shipping available?
Yes. Weight-based air surcharge shows at checkout — duties and customs covered, no surprise bills later. Five days versus the standard six-week ocean lead time.
