Mountain Equipment Helium 600 Women's Sleeping Bag

The Helium 600 is filled with 620g of minimum 700-fill power DOWN CODEX-approved duck down and uses 100% recycled Helium 20D outer fabric. This makes it incredibly warm, lightweight, and easy to compress for packing. It's a durable and versatile for early spring, autumn, or colder northern climates. 

Slant-baffle construction throughout the body ensures warmth, improves packability, and prevents the down from shifting, eliminating cold spots. A four-baffle system at the foot keeps your feet warm, while the five-baffle hood keeps down in place for maximum comfort.

The inside is lined with 100% recycled Supersoft 20D fabric with Fluorocarbon-free DWR, offering breathability and durability. A full-length Gemini™ zip baffle prevents heat loss, and the stiffened design stops the zip from snagging. The low-profile magnetic Lode Lock™ closure and easy-to-use collar drawcords add convenience, even in the dark.

With a technical Alpine 2.0 fit, this bag optimizes warmth while keeping weight down. Rated with a Good Night’s Sleep Temperature of -10°C (14°F), the Helium 600 provides reliable insulation in cooler conditions and at higher altitudes.

Technology

	Down Cycle The recycled Down Mountain Equipment comes entirely 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 a great choice 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.
