Sierra Designs Synthesis Women's 20

The Synthesis Women's 20 by Sierra Design is a synthetic fiber sleeping bag with an insulation of -7°C comfort. To suit all women hikers, from the coldest to the most restless at night, Sierra Design has equipped this sleeping bag with a double zipper opening allowing you to open the upper third of the sleeping bag completely and free your arms.

On one side, the zipper goes down under your chest to ensure good ventilation. On the other, you can open more than half of the sleeping bag to get in and out more easily. The anti-snag zippers are protected on the inside by a wide flap that will prevent your skin from touching uncomfortable materials or cold sources.

At the feet, a simple opening with insulated flap will encourage you to take your feet out or in as you wish without being hindered by the presence of a zip or velcro.

As with most of the sleeping bags in this range, you will benefit from an insulating collar that will compartmentalize your sleeping bag and prevent unwanted air from entering.

This three season sleeping bag will allow you to adjust, according to your wishes, the ventilation of the sleeping bag for a better adaptability to changing temperatures. Its durability is guaranteed by a SierraLoft synthetic fiber filling and a durable water repellent treatment (DWR) that will make it resist the slightest rain.
