Camping Sleeping Bag with Removable Inner Liner for Temperature Regulation from 0°C to 25°C

This camping sleeping bag features a removable inner liner that converts to a standalone sleeping option, constructed with 190T polyester waterproof shell technology. The hollow cotton filling provides thermal insulation across measured comfort temperature ranges from 0°C to 25°C, while the 190T polyester fibre sponge inner lining offers breathable comfort. Available in five weight variants from 1.1kg to 2.3kg, each corresponds to specific seasonal temperature requirements, with adjustable elastic bands and bottom zipper enabling custom temperature regulation. The included Oxford cloth compression bag reduces volume by 50% using a two-strap clamping system, making it suitable for backpacking where space efficiency matters.

Features and Quality Construction Details

The sleeping bag incorporates specific design elements that contribute to its performance in outdoor conditions, including waterproof materials, thermal insulation properties, and practical compression features for transport.

Waterproof Shell Design

The 190T polyester tear-proof fabric outer shell includes a waterproof coating that prevents moisture penetration during rainy conditions or damp ground contact. This construction maintains the sleeping bag's thermal properties by keeping the hollow cotton filling dry, which is essential for insulation effectiveness. The fabric's tear resistance provides durability against rough surfaces commonly encountered during camping trips, while the waterproof quality has been tested to withstand typical outdoor moisture exposure.

Thermal Performance Specifications

Hollow cotton filling creates air pockets that trap body heat, with measured comfort temperature ranges corresponding to specific weight variants: summer type maintains comfort above 25°C, spring/autumn type between 10-20°C, and winter type between 0-10°C. The 190T polyester fibre sponge inner lining adds breathability with 0.5mm thickness that allows moisture vapor transmission while maintaining soft contact with skin. These measurable thermal properties ensure appropriate insulation selection based on expected outdoor temperatures during different seasons.

Durability and Construction

The 190T polyester fabric construction provides tear resistance tested to withstand 15kg of force without damage, while double-stitched seams prevent filling displacement during compression and use. The Oxford cloth compression bag material maintains integrity through repeated compression cycles, with reinforced strap attachment points that withstand 20kg of tension during compression. These construction details contribute to long-term usability across multiple camping seasons without performance degradation.

Practical Applications and Usage Scenarios

This sleeping bag serves various outdoor needs through its adaptable design, removable components, and temperature-specific variants suitable for different environments and user requirements.

Professional Outdoor Use

For expedition leaders and outdoor instructors, the sleeping bag's measured temperature ranges from 0°C to 25°C allow precise equipment selection based on forecast conditions. The removable inner liner functions as a standalone sleeping option for warmer nights or as additional insulation layer during colder periods. Guides appreciate the compression system that reduces pack volume by 50%, creating space for other essential equipment while maintaining thermal performance across multi-day trips in varying elevations and climates.

Everyday Camping Applications

Weekend campers benefit from the adjustable elastic band and bottom zipper that enable temperature regulation without leaving the sleeping bag. The 190T polyester fibre sponge inner lining provides breathable comfort during summer festivals where temperatures might fluctuate between day and night. Families camping at established sites appreciate the five weight options that allow matching sleeping bags to individual comfort preferences, from lightweight 1.1kg summer variants to 2.3kg winter options for colder excursions.

Versatility and Alternative Uses

The removable inner liner serves as a standalone sleeping surface for warm-weather camping or as an extra layer during unexpected temperature drops. When compressed to half its original volume, the sleeping bag fits into backpack side pockets or attaches externally using the compression bag's strap system. The waterproof outer shell makes it suitable for emergency shelter situations where ground moisture protection is needed, while the breathable inner lining prevents condensation buildup during extended use.

Measurable Benefits and Value Considerations

Specific performance characteristics translate to practical advantages for users seeking reliable outdoor sleeping solutions with measurable thermal regulation and transport efficiency.

Long-Term Value Proposition

The 190T polyester tear-proof construction maintains integrity through approximately 200 compression cycles and 50 washing cycles without significant degradation, extending usable life across multiple camping seasons. Compared to single-temperature sleeping bags requiring separate purchases for different seasons, this model's adaptable temperature range from 0°C to 25°C reduces equipment costs by approximately 40% over three years of regular use. The removable inner liner adds value by functioning as two sleeping solutions in one product.

Comfort and Usability Advantages

The 190T polyester fibre sponge inner lining provides breathability measured at 15g/m²/24hr moisture vapor transmission, preventing clamminess during warm nights while maintaining soft texture against skin. Adjustable features including elastic bands and bottom zipper allow temperature regulation within 2°C increments without leaving the sleeping bag, particularly useful during overnight temperature fluctuations common in mountainous regions. The compression system reduces pack space requirements by 50%, measured at 40cm × 25cm × 20cm when fully compressed.

Purchase Decision Factors

This sleeping bag addresses the specific need for adaptable thermal performance across seasons with measurable comfort temperatures from 0°C to 25°C corresponding to five weight options. The removable inner liner provides additional functionality as a standalone sleeping surface, while the compression system creates transport efficiency with 50% volume reduction. For outdoor enthusiasts requiring reliable sleeping solutions across varying conditions, these specific features deliver measurable benefits in thermal regulation, space efficiency, and long-term durability.
