When space and weight matter most, like on biking adventures, kayak journeys, or long - distance backpacking, you need a sleeping bag that's super packable and can fit into small spaces like sterns, bike panniers, and bags. The lightweight, PFC - free NanoWave 25 Mummy - Style Sleeping Bag is your go - to for comfort around 25°F. Its Synthetic SpiraFil High Loft Insulation provides warmth even in wet conditions. The full - length zipper that wraps around the footbox allows for easy ventilation. A snagless draft tube stops air from getting in and prevents the fabric from getting caught. Regular length weighs 1300 g / 2.87 lbs, with a fill of Spirafil High Loft Synthetic Insulation and a fill weight of 705 g/ 24.87 oz.

Using this sleeping bag is easy. Just unroll it at your campsite and crawl in. It's great for keeping you warm on cold nights around 25°F. When it's time to pack up, roll it tightly and stuff it into your backpack or pannier. Make sure to close the full - length zipper properly for better insulation. To keep it in good shape, avoid getting it dirty as much as possible. If it gets wet, let it dry completely before storing it. Also, be careful when using the zipper to prevent any snags. Store it in a dry place to avoid mold and mildew.
