Rab's Solar Eco sleeping bags combine recycled synthetic materials and cutting edge technology to produce performance bags that are also eco friendly.
Rab says:
High performance, lower impact. The Solar Eco bags are built with recycled fabrics and recycled Stratus™ insulation made from 100% post-consumer PET bottles. Ideal for the mountain bothy goer, the globetrotting backpacker, and trekking in cool conditions, with a wide mummy shape for a comfortable night's sleep.
We’ve taken everything we know about lower impact design and applied it to what we do best. These resilient synthetic bags are filled with 100% recycled Stratus™ insulation, and lined and covered with a tough, 20D, recycled Atmos™ fabric with ripstop. Hardwearing, warm, and dependable, they are fast drying and cope with condensation or damp conditions.
The Solar Eco 3 is insulated with a double layer of Stratus™ insulation arranged in a concertina structure to trap warm air. The elastic internal quilting brings the lining and insulation closer to the user, helping to reduce pockets of cold air. The localised quilting simply means that the stitching which holds the insulation in place has been minimised to reduce the chance of cold spots. Perfect for three season climbing trips, mountain bivis, and backpacking adventures.
The Solar Eco has an adjustable hood which can be cinched in snug around the face to shut out the chill and an adjustable neck baffle to stop the heat escaping. The ¾ length zip has an additional baffle along its length that acts as an effective draught excluder with an anti-snag zip guard. The wide mummy fit offers space to find your most comfortable sleeping position, with room for extra layers should night-time temperatures plummet.
Our Verdict
Rab's Solar Eco 3 Synthetic sleeping bag fits into Rab’s Solar Eco range which combine recycled synthetic materials and cutting-edge technology to produce performance bags that are also eco-friendly.
The starting point is the Stratos recycled filling which has been carefully selected by Rab for its warmth to weight ratio and is incorporated with a differential fill, so there’s more on the top than the base where it is less effective. They’ve also incorporated their TILT technology to boost the performance by reflection of radiated heat.
The outer shell fabric is tough and water resistant making these bags more suitable for all applications, including bivying and tarp camping.
Have Rab achieved their goal? – well a leading edge down bag with an EN Comfort rating of 0C will typically weigh between 550 and 600grams, the Solar Eco 2 weighs 980grams and has a slightly better rating of -1C, so there is a significant weight premium for the synthetic version.
Interestingly Rab would say that the EN test doesn’t account for TILT very well and their Rab Sleep Rating is a bit better, especially in these synthetic bags. Their Solar Eco 1 bag is only 710grams and has a Rab Sleep Rating of 2C but an EN rating of 5C.
Whatever your judgement Rab have not only made a good contribution to the synthetic bag market but also taken a significant step forward in responsible manufacturing.
