The Rab Solar Eco 0 Regular is a lightweight mummy-style sleeping bag designed for warm-weather camping and trekking. With its summer comfort rating around 12 °C, it’s meant to keep you cozy on mild nights without adding bulk to your pack. The generous 215 cm length accommodates users up to about 185 cm tall, giving a bit of extra room to stretch out.
Filled with 100% recycled Atmos polyester insulation (41 gsm) and lined with recycled polyester, this bag strikes a balance between warmth and packability. The 20D recycled polyester shell is free from DWR and PFC treatments, relying on its tight weave to shed moisture naturally. At just 510 g, it falls into the superlight category, so you’ll hardly notice it strapped to your backpack and can move more freely when you’re on the trail.
The 41 gsm insulation rating indicates the weight of the fill per square metre, offering enough loft to trap warmth while keeping the overall weight down. The mummy shape tapers toward the feet, reducing dead space and improving heat retention, and the recycled shell fabric’s fine weave helps resist dampness without using added chemical coatings.
