Eisseide fabric is comfortable, not overly cold, and highly breathable, suitable for all seasons. The wide top opening provides unobstructed access, and the two U-shaped doors can be opened for easy entry and exit at any time. A practical tent buckle makes it easy to hang tent guy lines, keeping tension strong and preventing slack. The double-head (two-way) zipper allows convenient closure from inside or outside for practical operation. Use scenarios: - All-season family camping where ventilation and easy access are important. - Festival or group camping requiring quick entry and convenient entry from either side. - Campsites with wind or variable conditions, where taut guy lines and reliable tension enhance stability. This design emphasizes function, compatibility, size, material, and performance without extraneous embellishment.
