Taihua chooses comfortable and high-strength polyamide fiber material and uses 8D-20D ultrafine and super light fabric design. Our products with down or cotton filling are cold- proof, warm, waterproof, windproof, wear-resistant and tear-resistant. The fabric is tightening, tough, comfortable and breathable. The whole of our leeping bag is lightweight and easy to store, and the folding volume is smaller ( Such as an outdoor water bottle size). It is a must for outdoor camping and easy trip.
