Marmot Lost Coast 5 (M15418)

Warm and Easy to Maintain

The trekking sleeping bag Marmot Lost Coast 5 is a mummy-style bag with down insulation, designed for winter hikes and low temperatures. The filler is made of RDS-certified material consisting of 80% duck down and 20% feathers. The Down Defender technology ensures increased water resistance, which is particularly important in wet weather. The manufacturer claims comfortable use in temperatures down to -18 °C, and for women and those more sensitive to cold, around -10 °C. All temperature parameters have been tested according to ISO standards, confirming their accuracy and reliability.

An additional advantage of this model is its easy care: the sleeping bag can be machine washed (in cold water) and dried in a tumble dryer on low heat — a rare option for down products.

Practical and Lightweight

With dimensions of 205×82×57 cm, the Marmot Lost Coast 5 suits users up to 1.83 m tall. The sleeping bag weighs just 1.89 kg, an excellent figure for a winter model. The inner and outer layers are made of recycled polyester, reducing environmental impact without sacrificing strength and durability. The insulated zipper is protected from snagging and features a glow-in-the-dark loop for convenience in the dark.

Among the additional details are an anatomically shaped foot area to prevent heat loss, an internal pocket for small items, and a warm collar. The set includes a storage bag, although without a compression feature, so when folded, the sleeping bag takes up quite a lot of space (48×34×34 cm, about 55.5 liters). There's also no option to zip two mummy bags together.

If these minor details are not critical, the Marmot Lost Coast 5 can be confidently called a successful choice for winter hikes. It combines warmth, comfort, and ease of care, offering an attractive price for a down model.
