Sleeping Bag (synthetic)

Material Composition Assumptions

A typical synthetic sleeping bag weighing approximately 1.2 kilograms consists of several polyester-based components. The insulation comprises roughly 600 grams of synthetic polyester fill, representing about 50% of total weight. The outer shell fabric accounts for 300 grams or 25% of the product weight, while the inner lining contributes another 200 grams representing roughly 17% of total mass.

Additional components include zippers and hardware weighing approximately 80 grams, and various treatments such as durable water repellent coatings that add minimal weight but significant environmental impact. The insulation may utilize either virgin polyester or recycled content, with recycled options showing substantially lower carbon footprints despite slightly reduced performance characteristics.

Manufacturing Geography

Synthetic sleeping bag production concentrates primarily in Asian manufacturing hubs including China, Vietnam, and Indonesia. These regions dominate global textile manufacturing due to established supply chains, skilled workforce availability, and cost advantages. Chinese facilities handle the majority of polyester fiber production and bag assembly operations.

The regional grid intensity of 540 gCO2/kWh in China significantly influences the overall carbon footprint, particularly during energy-intensive processes like fiber production and fabric dyeing. Manufacturing in coal-dependent grids increases emissions compared to facilities operating in regions with cleaner electricity sources.

Regional Variation

Manufacturing Region	Grid Intensity	Estimated CCI Score	Adjustment vs Default
China	540 gCO2/kWh	55	Baseline
Vietnam	470 gCO2/kWh	52	-5%
Indonesia	615 gCO2/kWh	59	+7%
European Union	280 gCO2/kWh	47	-15%
United States	390 gCO2/kWh	50	-9%

Provenance Override Guidance

1. Submit detailed material composition data including percentages of recycled versus virgin polyester content, as recycled materials can reduce emissions by up to 35% compared to virgin alternatives.

2. Provide manufacturing facility energy source documentation, particularly renewable energy certificates or grid mix data, since electricity-intensive processes significantly impact overall footprint.

3. Supply transportation logistics information including shipping distances, modes of transport, and packaging specifications to refine transportation-related emissions calculations.

4. Document chemical treatment processes and coating applications, especially regarding PFC-free alternatives and Bluesign-approved treatments that affect both environmental impact and product lifespan.

5. Provide product durability testing results and expected lifespan data, as synthetic bags typically last 5-8 years compared to down alternatives lasting 15+ years.

Methodology Notes

• The CCI score represents cradle-to-gate emissions for a standard synthetic sleeping bag rated for 20°F temperature performance, including raw material extraction through manufacturing completion.

• Scope 3 emissions dominate the footprint at 70% due to upstream polyester production, while Scope 2 represents 22% from manufacturing energy consumption and Scope 1 accounts for 8% from direct facility emissions.

• The functional unit assumes normal consumer usage patterns over the product’s typical 5-8 year lifespan with standard care and maintenance practices.

• Exclusions include consumer transportation to point of sale, washing and maintenance during use phase, and end-of-life disposal impacts beyond initial manufacturing considerations.

• Data gaps exist around specific chemical treatment impacts and regional variations in recycled content sourcing, contributing to medium confidence levels in the overall assessment.
