This synthetic sleeping bag is made with Polarguard Delta (the most efficient type of synthetic insulation) and constructed with a shingle overlapping method to reduce cold spots. The shell is ripstop nylon and it fends off water extremely well, which is essential in a typical condensation-drenched winter tent. The long side zip has been carefully designed not to snag, and it runs well. Open up the bag and you’ll see good zip baffles. Get in and zip it back up and you’ll notice the EXL system comprising of elastic stitching that gently hugs the body, so reducing cold spots. The ‘shark’s toe’ foot is 5cm longer than the base too, so your feet can relax in a natural position without compressing the insulation (at least that’s the theory!). The good shoulder baffle can be easily adjusted and means you don’t have to have the hood fully drawn in if you are claustrophobic. The drawcords around the hood are easy to adjust though and the hood fits well. Add in the contoured hood and neck collar, and you’ve got all the luxury required for winter warmth. But confusing labelling suggests that both -14 and -20 deg C will be comfortable sleep temperatures (the Trail temp rating is -15 deg C). It is £180, so you could save money and still get a good bag (but would you get all those superb details?). Some may not like the feeling of the bag hugging them, even though this is a more efficient use of the insulation. I can’t really fault it more than this though.
