This Neutrino 800 down sleeping bag is a game - changer for winter mountain adventures. With a highly tapered mummy design, it cuts out excess bulk and offers outstanding warmth relative to its weight, making it ideal for fast and light four - season mountain missions. Filled with 800 grams of 800FP European goose down, which is stabilized in chevron - shaped baffles, this design reduces fabric usage compared to traditional horizontal baffles. The trapezoid boxwall baffle construction enables the down to fully loft, eliminating cold spots and maximizing warmth. Along the zip length and around the neck, additional baffles minimize heat loss. An adjustable drawcord on the hood lets you snug the bag around your face for extra warmth. The bag features a recycled nylon lining and a recycled, wind - resistant Pertex Quantum outer, making it eco - friendly and lightweight. The down comes with a Nikwax, fluorocarbon - free hydrophobic treatment to handle condensation. It has a ¾ length zip with anti - snag zip guards and a zipped internal stash pocket. It also includes a waterproof roll - top compression sack for easy storage. Hand - filled in the UK, our down bags ensure the down's loft and warmth as it's never been compressed before use.

Using your Neutrino 800 down sleeping bag is easy. First, unpack it from the compression sack and let it air out for a bit to allow the down to fully loft. Then, simply unzip the bag and crawl in. Use the adjustable drawcord on the hood to keep your face warm and cozy. For storage, roll it up tightly and place it in the waterproof roll - top compression sack. When it comes to maintenance, spot - clean any stains as soon as possible. Avoid machine - washing too often as it can damage the down. If you must machine - wash, use a gentle cycle with a down - specific detergent. After washing, dry it thoroughly on a low - heat setting, adding a few clean tennis balls to help fluff up the down. Keep the bag in a dry place when not in use to prevent mildew and maintain its loft and warmth.
