Cumulus - Quantum 450

Product Information

The Cumulus Quantum 450 uses Pertex Quantum (with Ripstop), which weighs just 35 gms/m2 and is the lightest grade of Pertex incorporating rip-stop reinforcement.  Pertex is water-resistant, windproof and breathable. Water resistance is essential to prevent the insulation material from becoming wet and losing some or all of its thermal properties while breathability is necessary for reasons of comfort and thermal efficiency. It should be noted, that the Cumulus Quantum 450 sleeping bag is not waterproof. Waterproofing is not desirable as body moisture must be allowed to evaporate out of the sleeping bag without creating condensation. The Cumulus Quantum 450 is insulated with 96:4 'diamond grade' Polish goose down which is recognised world-wide as being of the best available. Cumulus sleeping bags outperform competitive sleeping bags by their warmth to weight rating. Colours may vary.
