All right. Nana Ogawa 52r tent is made of single-layer 2 10T chunyafang fabric, which is thick, wear-resistant, elastic, wind-proof and rain-proof. Suitable for picnic and camping in spring and autumn. If camping in cold areas in winter, you can use Nana Ogawa 52r tent, but the warm-keeping effect will be greatly reduced. You can use a double-layer tent, because its outer tent is breathable and windproof, and its inner tent is rainproof and heat-proof, which can better survive in cold areas.
