The Mountain Equipment Helium 600 is a reliable three-plus season down sleeping bag that will take you from early spring to late autumn. Slanted box-wall baffles securely hold the responsibly sourced 700-fill duck down and minimise cold spots. The insulation is light, warm, and compressible, while the tapered shape maximises thermal efficiency. Supplied with a waterproof stuff sack, the Helium 600 is well set for UK backpacking and camping trips.

THREE+ Season
Three plus season sleeping bags feature increased insulation to help cope with the bitter temperatures you may experience in early spring and late autumn. These bags will also provide some users with enough warmth for year-round use.
DOWN
Ounce for ounce, nothing insulates as effectively as down. Down-filled bags are very light, warm, and compressible. When cared for correctly, they will last for many years. The negative? Down is susceptible to moisture; when wet, its insulating capabilities will significantly drop. That is why some sleeping bags feature down with a hydrophobic treatment - it helps the down perform better and dry faster if it does get damp. Down is measured in fill power; it represents how much loft the down has. The higher the fill power, the better the warmth-to-weight ratio will be.
