Marmot Helium is an ultralight and extremely warm down sleeping bag with a mummy shape, among the most high-performing products from the American brand, perfect for serious climbers and hikers!
The insulation is RDS certified, meaning it contains down and feathers sourced from certified farms where geese and ducks are raised in accordance with animal welfare principles and criteria.
The 800+ Fill Power provides a warm shelter and thanks to the outer materials, it is also durable, lightweight, insulated, and waterproof, enhanced by the Down Defender treatment that improves water resistance in humid conditions! The YKK zipper also features a double safety button with a full closure, allowing you to stay warm by retaining heat while the second zipper facilitates access to the bag, ventilation, and temperature regulation based on your needs. The foot area has an anatomical and enveloping design that preserves warmth, while the head is protected by the adjustable padded Nautilus hood. The compression sack for transport is included.
