Starting in 2016, the feather used in all Sea to Summit sleeping bags will be certified R.D.S (responsible down standard). The R.D.S. standard guarantees the proper treatment of farmed geese and commits producers to meet certain criteria on feather production. For Sea To Summit this is a further step towards respect for the natural environment.

Ultra dry down :

Sea to Summit has developed a feather treatment that allows: - to prevent it from getting wet - to keep it naturally swollen - to dry more quickly - to repel microbes and bacteria - to extend the life of your sleeping bag. This hydrophobic polymer-based treatment keeps 60% more swelling in wet conditions and absorbs 30% less moisture than a sleeping bag with an untreated loft.

Thermolite :

Sea to Summit is developing a new range of sleeping bags using a synthetic Thermolite filling. Thermolite maintains a certain amount of inflation by trapping air while being compressible. Compared to a feather-lined sleeping bag, the synthetic filling has the advantage that it dries very quickly and is therefore easy to maintain and ideal for use in wet conditions.

Pack store wash :

All Sea to Summit sleeping bags come with 2 bags: - An Ultra Sil compression bag, light and resistant - A storage bag to keep the down in optimal conditions, a quality bag that also allows practical and smart storage in shops and can be transformed into a wash bag.
