Alvivo – Arctic Extrem Ultra – Synthetic Sleeping Bag

With its anatomical foot box and very lightweight hollow fibre insulation, this particularly warm synthetic sleeping bag is ideal for expeditions and mountaineering – the Arctic Extreme Ultra by Alvivo!
4-channel hollow fibre made of polyester has been used for this warm mummy sleeping bag. The fibres have been siliconized so they absorb less moisture than conventional insulation. The hood is designed to fully envelop the head without making you feel restricted as you sleep. The collar with additional draft collar can be quickly adjusted with the integrated drawstring to optimally regulate the temperature in the sleeping bag. The chambers have been designed so that all of the synthetic fibres can expand to their maximum volume and provide reliable insulation. The outer material consists of a robust, triple-layer design and protects the insulation against moisture absorption. The slightly wider mummy cut of the sleeping bag offers efficient temperature management with a simultaneously low weight. The warm winter sleeping bag can quickly be stuffed into the compression stuff sack supplied to save space during transport.
The hood of the Alvivo Arctic Extreme Ultra synthetic sleeping bag has a slightly larger design, and the spacious cut of the upper body gives you lots of freedom of movement when sleeping in the tent.
