Product Description


1.8KG 400GSM Single Blue Dual Color Waterproof 190T Polyester Envelope Sleeping Bag


Product Description & Features,

A polyester sleeping bag is a type of sleeping bag that is made primarily from polyester fabric. Polyester is a synthetic material known for its durability, water resistance, and insulating properties. Sleeping bags made from polyester are popular among outdoor enthusiasts, campers, hikers, and backpackers due to their lightweight nature and ability to retain warmth even when damp.

Polyester sleeping bags come in various shapes, sizes, and temperature ratings to accommodate different climates and seasons. Some common features of polyester sleeping bags include a zipper closure to secure the bag, a hood or drawstring to cover the head and retain heat, and often a stuff sack for convenient storage and transport.

Polyester sleeping bags come with a variety of features, depending on the specific model and brand. Here are some common features you might find in a polyester sleeping bag:

  1. Shell Fabric: The outer shell of the sleeping bag is typically made from polyester fabric, which provides durability, water resistance, and protection against wear and tear.

  2. Insulation: Polyester sleeping bags can have different types of insulation, such as synthetic fibers or polyester fill. These materials help trap body heat and keep you warm during cold nights.

  3. Temperature Rating: Sleeping bags are often assigned temperature ratings to indicate the lowest temperature at which they can provide adequate insulation. Common ratings include three-season bags (designed for spring, summer, and fall) and winter bags (designed for colder temperatures).

  4. Shape and Design: Polyester sleeping bags are available in various shapes, including rectangular, mummy, and semi-rectangular. Rectangular bags provide more space for movement, while mummy bags are more form-fitting and offer better heat retention.

  5. Zipper Closure: Most sleeping bags have a full-length zipper that allows you to open and close the bag. Some bags may have two-way zippers, which provide the flexibility to vent the bag from the bottom or top for temperature regulation.

  6. Hood: Many polyester sleeping bags come with a hood that can be cinched around the head to trap heat and provide added warmth.

  7. Draft Tubes and Collars: Draft tubes are insulated tubes that run alongside the zipper to prevent cold air from entering the sleeping bag. Draft collars are insulated sections around the neck area to minimize heat loss.

  8. Pockets: Some sleeping bags have internal or external pockets where you can store small items like phones, flashlights, or personal belongings for easy access.

  9. Compression Sack: A compression sack is often included with polyester sleeping bags. It allows you to compress the bag into a smaller size for convenient storage and transportation.

  10. Weight and Packability: Polyester sleeping bags are generally lightweight compared to other materials. The weight and packability can vary based on the insulation type, temperature rating, and overall design of the bag.

The advantages of polyester sleeping bags include their affordability, ease of maintenance, and quick-drying properties compared to natural materials like down. Polyester is also less susceptible to mold, mildew, and insect damage, making it suitable for various outdoor conditions. Additionally, polyester sleeping bags tend to be hypoallergenic, making them a good choice for individuals with allergies.

However, polyester sleeping bags may not provide the same level of insulation as down-filled sleeping bags in extremely cold temperatures. They also have a lower compressibility, meaning they may take up more space when packed. Some people also find polyester to be less breathable compared to natural fabrics.

When choosing a polyester sleeping bag, consider factors such as the temperature rating, intended use (e.g., camping, backpacking), the user's body size, and personal preferences. It's always a good idea to check reviews and ratings before making a purchase to ensure the chosen sleeping bag meets your specific needs.


  1. Are polyester sleeping bags suitable for cold weather camping?
    Polyester sleeping bags can provide insulation and warmth, but they may not be as effective as down-filled sleeping bags in extremely cold temperatures. It's important to consider the temperature rating of the sleeping bag and choose one that is appropriate for the expected conditions.

  2. Can I wash a polyester sleeping bag?
    Yes, polyester sleeping bags are generally machine washable. However, it's important to follow the manufacturer's instructions for washing and drying to ensure the longevity of the bag. Some sleeping bags may require special care or professional cleaning.

  3. Are polyester sleeping bags waterproof?
    Polyester fabric is naturally water-resistant to some extent, but most polyester sleeping bags are not completely waterproof. They can withstand light rain or moisture, but prolonged exposure to heavy rain or submersion in water may result in water seeping through. To enhance water resistance, you can look for sleeping bags with a durable water repellent (DWR) coating or consider using a waterproof stuff sack or bivy sack.

  4. How do I choose the right size of a polyester sleeping bag?
    Sleeping bags come in different lengths and widths to accommodate various body sizes. It's important to consider your height and body shape when selecting a sleeping bag. Most manufacturers provide size charts or guidelines to help you choose the right size. Additionally, some sleeping bags offer different sizes or have adjustable features to ensure a comfortable fit.

  5. Can I use a polyester sleeping bag for backpacking?
    Yes, polyester sleeping bags are commonly used for backpacking due to their lightweight nature and durability. When choosing a sleeping bag for backpacking, consider factors such as weight, packability, and insulation performance to ensure it meets your specific needs and can be easily carried in your backpack.

  6. Are polyester sleeping bags hypoallergenic?
    Polyester is generally considered hypoallergenic, meaning it is less likely to cause allergic reactions compared to natural materials like down. However, individual sensitivities can vary, so if you have specific allergies or sensitivities, it's best to check the product description or consult with the manufacturer to ensure the sleeping bag is suitable for you.

  7. Can I use a polyester sleeping bag for indoor sleepovers or guest accommodation?
    Yes, polyester sleeping bags can be used for indoor sleepovers or guest accommodation. They provide a comfortable and portable bedding option. However, keep in mind that sleeping bags designed for outdoor use may have features like water resistance or insulation that may not be necessary for indoor use.
