US-based outdoor specialist Slumberjack has expanded its Go Light, Go Fast, Go Small product line with the addition of two new sleeping bags.

The Solera +15ºF sleeping bag mimics the size, shape and contours of the female body with its hourglass shape. It has extra insulation in the hood, upper torso and footbox for added comfort.

The Solera is filled with Thermolite Extreme insulation, which is a blend of three fibres (denier, thermal and hollow core). All of these fibres, working together, provide warmth and compactability. The exterior of the bag is made from a nylon diamond ripstop material, which is said to be durable and wind- and water-resistant. The interior of the bag features a polyester-taffeta liner.

A double-offset, differential-cut construction is used to enhance the durability of the bag. The construction also helps to eliminate cold spots, providing an even distribution of insulation throughout the bag. The sleeping bag also features an insulated draft tube and adjustable storm collar to keep cold air out and warm air in.  It has a fully-contoured hood which is said to wrap snugly around the user’s head which can also be turned inside-out to act as a pillow.

The second addition to the line is the Calypso +25ºF youth-sized mummy sleeping bag. The Calypso is designed especially for children and offers the same high-end features and quality performance.
