Ultra Compact Sleeping Bag Ultralight Weight Only 475 grams 6 to 11°C

The Ultra-C is a truly compact sleeping bag designed for ultralight hikers and minimalist adventurers. Weighing just 475 grams, it compresses down to a size that fits comfortably in one hand. Despite its size, it offers impressive warmth with a comfort range between 6°C and 11°C.

What makes this compact sleeping bag so light and effective is the 95% white goose down filling. This premium insulation compresses easily and lofts up when unpacked, creating warm air pockets throughout the bag. The longer it’s left to puff out, the better the thermal efficiency.

Designed with practicality in mind, the sleeping bag is fitted with a reliable YKK zipper, accessible from both inside and out. To prevent unzipping during the night, a soft Velcro closure is added at the top of the bag for secure comfort.

Tips On Using This Compact Sleeping Bag

To get the most from your compact sleeping bag, keep it dry at all times. Wet or damp down loses its loft and cannot trap heat effectively. The insulation only works when the down is fully expanded within the baffles.

When your sleeping bag arrives, take it out of the compression sack and let it air for several days. This restores loft after long storage and removes any residual manufacturing odour. Shaking it occasionally during this time also helps it puff up.

Always store your sleeping bag in the large storage sack when not in use. Avoid long-term compression, as this affects its ability to loft and insulate. On trips, take the sleeping bag out as soon as you arrive at your hut or campsite. Giving it time to reach full loft ensures a warm night ahead.

Conclusion

The Ultra-C is ideal for lightweight tramping, bikepacking, or ultralight travel where every gram counts. Despite its minimalist weight, it provides the warmth needed for spring, summer, or mild autumn nights. If you’re looking for a compact sleeping bag that won’t fill your pack or drag you down, this is one of the best choices available.
