Rab Solar 4 Synthetic Sleeping Bag

The Solar is a lightweight, warm and super reliable sleeping bag for damp, cold conditions. Perfect for our UK winters then! It uses a tough ripstop outer fabric and Rab's own Stratus synthetic insulation. Insulation:
Rab use their own Stratus insulation throughout the bag. This is made entirely from a high-quality polyester and insulates even when wet, so you won't get too cold if you spill your morning coffee over yourself. When you're ready to pack the bag away, Stratus will compress down super small and weighs very little.

Outer fabric:
Surrounding all this clever insulation is a tough yet lightweight 20D ripstop polyester with a durable water repellent coating. Inside, a softer 20D polyester sits next to skin and feels a lot like a duvet you'd find at home.

An internal stash pocket is a perfect place to store a phone or other electronics to keep them warm during the night, while an internal 3D collar and hood keeps the warmth in by creating a seal around your neck. This can be adjusted via a drawcord in the hood depending on how warm you need to be. A 3/4 length main zip reduces the pack size compared with a full-length zip and features glow in the dark zip pulls for ease of use in the night. Lastly, an included compression stuffsack squeezes the bag down to a fraction of its original size. Please note, this compression sack shouldn't be used to store the bag for long periods of time.

This insulation is kept in place via two different construction methods; a shingled and blanket construction. As the name hints, a shingled construction essentially layers pieces of insulation over each other a lot like a shingled roof, while a blanket construction uses a larger sheet of insulation in. Well, a blanket. The blanket construction is used for the base as it resists compression better, while a shingled construction reduces the overall pack size yet provides bucket loads of warmth. An angled foot box allows your feet to relax into their natural upright position without compressing the insulation above, in turn keeping you warmer.
