Ultralight and compact sleeping bag for summer hiking and travel
The compact sleeping bag LW180 is designed for summer outings and lightweight travel, with a weight of 680 g for the Standard version and 760 g for the Large version, and a compressed size of 12 x 29 cm. The 80 g/m² silk-like synthetic fiber filling and the 20D 380T polyester taffeta fabric for both the shell and lining provide a soft and breathable feel against the skin, suitable for summer nights. The indicated temperatures (15°C comfort / 8°C limit) are manufacturer values: in the absence of an explicit measurement standard, plan for an extra layer from 10°C in real-world conditions.
Versatile design: sleeping bag, blanket, or double bag
The two-way YKK zipper allows the LW180 to be opened completely to be used flat as a light blanket, or to be zipped together with a second compatible bag for duo use. Velcro tabs keep the zipper in the open position without being annoying. This level of versatility compensates for the lack of a winter temperature range: the LW180 is a summer sleeping bag or a light addition to integrate into a layering system, not a 4-season bag.
20D 380T fabric: durability and skin feel
The 20D 380T polyester taffeta fabric used for both the shell and lining offers good abrasion resistance for such a fine yarn weight, a common compromise on ultralight summer sleeping bags. The 380T thread count (weave density) contributes to the fabric's durability over time despite its fineness.
Silk-feel filling: a texture designed for summer
The silk-like synthetic fiber filling provides a smooth, soft feel against the skin, unlike the coarser texture of standard synthetic filling. This texture enhances the comfort of this compact sleeping bag on warm nights when it is often used unfolded, as a single layer, directly against the skin.
If you prefer a joinable envelope shape with synthetic insulation better suited for static trips, the Naturehike H150 is the camping benchmark in this family.

The Naturehike LW180 has a comfort temperature of 15°C and a lower limit temperature of 8°C. These values apply under standard conditions: sleeper in thermal base layers, on an insulated sleeping mat. It is designed for trek use (summer).
The Naturehike LW180 is filled with Synthetic fiber. Synthetic insulation keeps insulating when damp, dries quickly and needs no special care — suited to changeable conditions or family trips. The Naturehike LW180 weighs 680 g, which places it in the ultralight category.
For static camping in France, a bag with a comfort temperature between 5°C and 15°C covers most situations from spring to autumn. Synthetic fill is often preferred for camping because it is easy to care for and tolerates humidity. Down is preferable if weight and packed size matter, especially if gear is carried on foot.
Night-time warmth when camping depends on several elements: a sleeping bag suited to the expected temperature, an insulated sleeping mat to cut heat loss through the ground (often underestimated), and dry clothes worn only for sleeping. Eating a hot meal before bed also helps the body produce heat during the night.
A down sleeping bag can be machine-washed at 30°C maximum on a delicate cycle, with a down-specific detergent (standard detergents damage the down). The machine should have a capacity of at least 7 kg. Low-heat tumble drying with tennis balls is essential to restore the down's loft. Do not spin at high speed.
