Here's what other sites are saying:
Protect your Exped Mira III Tent from wet ground, sharp rocks and poking roots with the Exped Mira III Footprint. This Exped groundsheet is cut to fit perfectly beneath this tent so it won't channel water underneath you and still offers enough space to protect the tent floor. Sleep soundly knowing your Exped tent is safe and your bag will be dry in the morning.
