Cumulus Aerial 330 - Ultralight down sleeping bag with innovative design
TheAerial 330 from Cumulus is a groundbreaking down sleeping bag designed for adventurers who demand maximum performance in minimum weight - without compromising on comfort. Through a combination of ultra-lightweight materials, 900 FP high-quality down fill and thoughtful design solutions, the Aerial 330 offers an unbeatable weight-to-insulation ratio.
Minimalist construction for maximum performance
When sleeping outdoors, the main insulation comes from underneath your sleeping pad - the down in the bottom of the sleeping bag is still compressed under the weight of your body. To save weight, the Aerial range therefore features a 'false bottom' construction, where the underside is just a single layer of super-light Toray Airtastic® fabric with no extra down filling. This innovative choice makes the sleeping bag significantly lighter without compromising on warmth.
In addition, the precise trapezoidal chamber design and lack of zipper further contribute to keeping the weight down. The result is an ultra-light sleeping bag weighing only 483g with a comfort temperature of -1°C, placing the Aerial 330 at the very top of down sleeping bags in its class.
For gram hunters and extreme adventures
Whether you're planning a multi-day hiking adventure in technical terrain, taking part in a long-distance cycling race, or looking for equipment for fast and easy mountain hiking, the Aerial 330 is the obvious choice. It's made for outdoor enthusiasts who carefully weigh every ounce of their pack and value the freedom of a lighter adventure.
