Ogawa's Lodge Shelter T/C Inner Tent for 5 people, offering a comfortable camping experience. Used twice after purchase. A PVC sheet was placed under the bottom for protection, so there is almost no dirt. - Brand: Ogawa - Model Name: Lodge Shelter T/C Inner Tent for 5 people - Type: Inner Tent Not Ⅱ. Made of technical cotton with a sturdy PVC bottom. (Ⅱ has windows on both sides, but the bottom is not PVC. This one is overwhelmingly warmer in winter.) Thank you for looking.
