[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-5 One embodiment provided by this utility model: A sleeping bag without cold spots includes a sleeping bag body 3 and a sleeping bag mat 1. The surface of the sleeping bag body 3 is provided with a "Z" pattern 11. A windproof strip 2 is fixedly connected to the surface of the sleeping bag mat 1. The surface of the windproof strip 2 is provided with a down filling port 21. A main zipper 5 is movably connected to the surface of the sleeping bag mat 1. A side zipper 51 is movably connected to the surface of the sleeping bag body 3. When using the sleeping bag mat 1, an air cushion or moisture-proof mat can be added to the surface of the sleeping bag mat 1, which will make it more comfortable and enhance its warmth.

[0018] Furthermore, the "Z" pattern 11 is evenly distributed on the surface of the sleeping bag body 3. The sleeping bag mat 1 is made of waterproof material. There are two sets of windproof strips 2, and the two sets of windproof strips 2 are distributed at both ends of the sleeping bag mat 1. The surface of the sleeping bag body 3 usually uses a grid to fix the fleece, but the effect is not good and the fleece is easy to slip or clump. The "Z" pattern 11 makes the fleece locking effect better.

[0019] Furthermore, the sleeping bag body 3 is movably connected to the sleeping bag mat 1 via the main zipper 5. The sleeping bag body 3 is connected to the windproof strip 2 via the sleeping bag mat 1. The sleeping bag body 3 is also filled with down. The sleeping bag body 3 is made of wear-resistant and waterproof material. The sleeping bag mat 1 is made of the same material as the sleeping bag body 3. The sleeping bag mat 1 and the sleeping bag body 3 are connected via the main zipper 5.

[0020] Furthermore, the down filling port 21 is movably connected to the sleeping bag mat 1 via the windproof strip 2. The windproof strip 2 is movably connected to the sleeping bag body 3 and the main zipper 5. The windproof strip 2 is filled with down near the down filling port 21, which makes the windproof strip 2 more effective in preventing wind. The windproof strip 2 is set on both sides of the sleeping bag mat 1 to prevent air leakage caused by the air cushion added to the surface of the sleeping bag mat 1.

[0021] Furthermore, a sleeping bag cap 4 is fixedly connected to the surface of the sleeping bag mat 1, and a sleeping bag cap 4 is movably connected to the surface of the sleeping bag body 3.
