A down sleeping bag for children for cool nights
The children's sleeping bag Aegismax Kid 400 is sized for smaller frames (160 × 70 cm), with an 800-fill power white goose down filling. Its comfort temperature of 8°C covers spring and autumn nights, while the limit temperature of 3°C remains a theoretical safety benchmark, not to be confused with extended comfortable use.
Baffle construction: insulation designed to minimize cold spots
The box baffle construction maximizes down loft volume while reducing the cold spots typically seen with simple stitching. The 20D IFlex nylon outer fabric, with a DWR treatment, allows surface moisture to bead off to keep this compact sleeping bag dry for longer.
Adjustable collar and snag-free zipper: the detail that seals in heat
A collar with an independent drawstring helps minimize heat loss at the neck without having to fully close the hood. The YKK zipper is lined with an anti-snag strip, and the non-stick PAIHO velcro prevents snagging on surrounding fabric during the repeated handling typical of children's use.
Compression sack and storage mesh bag included
This compact down sleeping bag comes with an ultralight compression sack for transport and a breathable mesh storage bag for between trips, a practice that preserves the down's loft over time. Two hang loops at the feet also make it easy to dry after a damp night.
For a child who is growing fast and for multiple camping seasons, the Naturehike C300 offers an expandable system that grows from 160 to 190 cm, whereas the Kid 400 remains a fixed size but gains in compressibility thanks to its down filling.

The Aegismax Kid 400 has a comfort temperature of 8°C and a lower limit temperature of 3°C, measured to the EN 13537 standard. These values apply under standard conditions: sleeper in thermal base layers, on an insulated sleeping mat. It is designed for child, camping, family hiking use (Spring / Autumn).
The Aegismax Kid 400 is filled with 800 fill power white goose down, 60/40 ratio, 400g. Down offers the best warmth-to-weight ratio: it packs down small and weighs less than synthetic insulation of equivalent warmth, which makes it the natural choice for wild camping and multi-day trekking. On the other hand, it loses efficiency when damp and needs careful drying. The Aegismax Kid 400 weighs 700 g, which places it in the ultralight category.
