Mountain Equipment Helium 250 Women's Sleeping Bag

Using 261g of minimum 700-fill power DOWN CODEX-approved duck down and a high-performance, 100% recycled Helium 20D outer fabric, the Helium 250 is incredibly efficient, lightweight, and packable—perfect for warm-weather backpackers aiming to reduce pack size.

Slant-baffle construction maximizes warmth, improves packability, and prevents down migration, ensuring consistent warmth and eliminating cold spots. A four-baffle system at the foot focuses warmth around the feet, while a five-baffle system in the hood optimizes comfort and keeps the down precisely positioned.

Inside, a 100% recycled Supersoft 20D lining fabric with Fluorocarbon-free DWR provides breathability, durability, and long-lasting comfort. A full-length Gemini™ entry zip baffle virtually eliminates heat loss. It is stiffened to prevent snagging, with a low-profile magnetic Lode Lock™ closure and user-friendly collar drawcords, even in the dark.

Designed with a technical yet comfortable Alpine 2.0 fit, Helium bags optimize thermal performance while minimizing weight. With a Good Night’s Sleep Temperature of 1°C (34°F), the Helium 250 is ideal for warm-weather camping and backpacking.

Technology

	Down Cycle The recycled Down Mountain Equipment comes from post-consumer goods—unwanted clothing and bedding collected by waste recycling companies.
	A Good Night's Sleep Guaranteed We are so confident that our sleeping bags will keep you warm and comfortable that, in addition to the EN13537/ISO23537 laboratory ratings we quote, every Mountain Equipment sleeping bag comes with a separate ‘A Good Night’s Sleep Guaranteed’ temperature rating.
	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.
