Full Review

Mountain Equipment Helium 250 Sleeping Bag - Regular Blue Review

Overview: The Mountain Equipment Helium 250 is a lightweight, down-filled sleeping bag designed for backpacking and trekking in temperate conditions. This model, available in blue, boasts a comfortable temperature rating of 250°F (-17°C) and packs down to a remarkably small size.

Key Features Analysis:

  • Down Fill: The Helium utilizes ethically sourced European goose down with a fill power of 800 cuin. This provides excellent warmth-to-weight ratio, crucial for lightweight backpacking. Down is naturally compressible, leading to the bag's impressive packability.
  • Shell & Lining: Constructed from durable Pertex Quantum fabric, both the shell and lining offer tear resistance and a smooth feel against the skin. The use of this lightweight material contributes significantly to the overall weight savings.
  • Baffle Construction: The Helium features a box baffle construction throughout. This design prevents down migration and ensures even heat distribution across the bag.
  • Hood & Draft Collar: A contoured hood with an adjustable drawcord helps seal in warmth, while a draft collar at the opening minimizes heat loss through the top of the bag.

Pros:

  • Ultra-Lightweight: Weighing only around 1 lb 9 oz (670g) in the regular size, this sleeping bag is incredibly lightweight, making it ideal for backpacking and minimizing pack weight.
  • Excellent Warmth: Despite its light weight, the 800 fill power down provides impressive warmth for a 25°F/-17°C rating.
  • Compact Pack Size: The Helium packs down incredibly small, fitting easily into most backpacks.
  • Durable Construction: The Pertex Quantum fabric is robust and withstands regular use.
  • Ethical Down: The use of ethically sourced European goose down ensures responsible sourcing practices.

Cons:

  • Limited Temperature Rating: While suitable for mild to cool temperatures, the Helium may not be warm enough for extended periods in colder conditions (below 25°F/-17°C).
  • Price Point: This sleeping bag is on the pricier side compared to some alternative lightweight options.

Final Verdict:

The Mountain Equipment Helium 250 is a top-performing lightweight sleeping bag that excels in warmth, packability, and durability. While it may not be suitable for extreme cold, its performance in temperate conditions makes it an excellent choice for backpackers and trekkers prioritizing weight savings without sacrificing warmth. Its ethical down sourcing adds value to this already impressive product.
