Rab Solar Eco Sleeping Bag

The Solar Eco 3 is rated for 32 degrees Fahrenheit, making it a solid choice for three-season camping and backpacking. While it handles variable mountain conditions well, it is best suited for mild to cool nights rather than deep winter temperatures.

Unlike down, the Recycled Stratus synthetic insulation retains its loft and warmth even when wet. Combined with the water-resistant shell, this bag is a reliable option for humid environments or unpredictable weather where moisture is a concern.

The dual-layer concertina construction is designed to maximize loft, which traps more air to keep you warmer. This method helps the synthetic insulation mimic the performance of down while maintaining the durability and moisture resistance of a synthetic fill.

The bag features an anti-snag internal zip guard specifically designed to prevent the fabric from catching in the zipper track. This makes getting in and out of the bag much smoother, even in the dark.

The Solar Eco 3 packs down to 40 x 22 cm. While synthetic bags are generally bulkier than down equivalents, this size is manageable for most backpacking packs and provides a good balance between insulation and portability.

Yes, it includes several heat-retention features, including an insulated zip baffle, a neck baffle, and an adjustable hood with an elasticated drawcord. These elements work together to seal in warmth and prevent cold drafts from entering the bag.
