Product description
The Sphere UL 3-Season by Mammut is your ideal companion for touring from spring through to fall! The down sleeping bag is perfectly suited for trekking and mountain hiking. Due to its very light weight and small packed dimensions it will leave you with extra room for your gear or provisions.
Mammut have consistently focused on saving weight, choosing only the lightest, most durable materials for this high quality down sleeping bag. The Sphere UL 3-Seasons outside fabric is literally light as a feather, totally windproof, moisture-repellent and permanently waterproof through DWR treatment. This can be a crucial advantage when you are out and about, as even water condensation in your tent or bivy sack can reduce the insulation performance of downs.
For the down sleeping bags fill, Mammut rely on top quality down with a fill power of 800 cu in and a down to feather ratio of 95/10. This makes for a sleeping bag that is conveniently lightweight and highly compressible but, nevertheless, capable of developing a strong heat capacity. Cold spots are avoided as the fill is secured in wave shaped baffles. The perfectly shaped hood with its draft collar, as well as the three quarter length zip further minimize any loss of heat. The hoods special design provides unobscured views even when it is closed.
The Mammut Sphere UL 3-Season is a good choice for anyone looking for a 3-season down sleeping bag for long trips that require elaborate gear and where every ounce of weight truly matters!
