Mountain Equipment Helium GT 250 Sleeping Bag (1°C/34°F)

The Helium GT series has a roomier fit, perfect for extended use and comfort. Made with 289g of 700-fill power CODEX-approved duck down and 100% recycled Helium 20D fabric, the Helium 250 is lightweight and packable, ideal for warmer weather minimalist trips.

Slant-baffle construction maximises warmth, improves packability, and prevents cold spots by keeping it down in place. A four-baffle system at the foot ensures warmth around the feet, while a five-baffle hood maintains comfort and optimal down placement.

Inside, the 100% recycled Supersoft 20D lining with fluorocarbon-free DWR adds breathability and durability for long-term use. The full-length Gemini™ zip baffle reduces heat loss, and the stiffened design prevents snagging. The Lode Lock™ closure and collar drawcords are easily adjusted, even in the dark.

The Helium GT features a more generous fit without compromising performance, offering extra space compared to the Alpine fit. With a Good Night's Sleep Temperature of 1°C (34°F), it's perfect for warm-weather backpacking and camping trips.

Technology

	Down Cycle The recycled Down Mountain Equipment comes from post-consumer goods, unwanted clothing and bedding collected by waste recycling companies.
	Down 700 Down is the finest insulator. Manmade insulations cannot match its warmth-to-weight ratio, compressibility, long lifespan, and softness. Duck Down is great for insulated clothing and equipment for all but the most serious expeditions.
	Helium Helium fabrics are exceptionally light, compressible, and soft. Their densely woven construction ensures the highest levels of down-proofing and wind resistance.
	Fair Wear Fair Wear ensures that the clothing is produced under high standards that promote ethical working conditions.
