The Sweet Smell of Sleep


Odour control technology company, Polygiene, has partnered with leading outdoor brand, Rab, to launch the first technical sleeping bag featuring Polygiene’s anti-microbial fabric treatment.

The Rab Neutrino is a minimalist, down-filled sleeping bag designed for mountaineering, backpacking and multi-day adventures where the warmth-to-weight ratio is of prime concern.

Polygiene’s silver salt treatment of the interior lining means it won’t need to be washed as much, thanks to the anti-odour technology. With washing and drying accounting for two-thirds of the environmental impact of a product, the anti-odour treatment helps saves water, energy, time and money as well as improves the product lifespan.

Perfect for adventurous alpine climbers and mountaineers the Rab Neutrino is not only lightweight but also ensures a fresh night’s sleep. There’s no need to hang your sleeping bag out to air.

Polygiene’s CEO, Christian von Uthmann says, “this is the first time we will be included in a highly technical and performance-driven sleeping bag collection.  We’re very proud to partner with Rab.”  Uthmann continues, “when you settle down for the night, the only smells you want are the forest pine and woody, earthy scents, definitely not the stink of your own or tent mate’s sleeping bag”.

Available in four weights, the Neutrino sleeping bag is hand-filled in Derbyshire with high-quality Hydrophobic European goose down.  Lightweight Pertex Quantum, a lightweight yet durable fabric to ensure maximum loft without increasing the weight.

Minimising pack size but maximising comfort, the Rab Neutrino is styled in a ‘mummy taper’ shape and has a close fitting internal collar.  Other features include quality YKK zippers throughout, an internal collar and hood draw cord, anti-snag zipper webbing tape and a unique trapezoidal baffle chamber design, to eliminate cold spots.


The Rab Neutrino models are available in:


  • The Neutrino 200 has a Rab Sleep Limit of 1.5 degrees, RRP £220
  • The Neutrino 400, has a Rab Sleep Limit of -4 degrees, RRP £310
  • The Neutrino 600, has a Rab Sleep Limit of -12 degrees, RRP £380
  • The Neutrino 800, has a Rab Sleep Limit of -20 degrees, RRP £450

Polygiene Permanent Odour Control™ is a silver chloride treatment made from recycled silver from electronic waste. It inhibits the growth of viruses, bacteria and fungi and the odour that arises from them.  Bad smells develop when odour-causing bacteria settle into the fabric, mix with sweat and multiply. The treatment is permanent and products treated with Polygiene stay fresh and remain hygienic between washes, earning Polygiene’s tagline “Wear More. Wash Less®”.
