Our MicroStretch Liner is made in Portugal, our first product made in the EU. The soft and stretchable polyester microfibre feels smooth on the skin and gives you extra room to move. It allows you to sleep comfortably and walk around when you need. The perfect travel companion for warmer climate or to enhance the temperature range in any sleeping bag, it is lightweight and small to pack. Sleep, sit or walk anywhere you like, the hood keeps your head and neck safe from cold air currents. The arm sleeves are long enough to flip them over the hands at night and the bottom cord can open the MicroStretch Liner and tie it around your waist in seconds for instant freedom to move. The light grey contrast colour around the bottom makes it easier to find it also in low light, when you want to slip in, or open and close it. Practical in hostels and camping, on planes, trains and buses, in bed or sleeping bags and even at home, on the couch.

Der Strece Liner war schon auf meiner Hüttentour im Einsatz und ich fand ihn perfekt! Wie eine 2. Haut und sehr leich! Den gebe ich nicht mehr her!!

Josef Obermeier

Sehr angenehm!

Christina Buchmann
Wirklich gut

Sehr komfortabel, ich habe darin wirklich gut geschlafen. Besonders schön ist die Bewegungsfreiheit für die Beine, in einem herkömmichen Hüttenschlafsack ist man dagegen immer sehr eingeschränkt. Positiv ist auch, dass man die Füße unten mal kurz rausstrecken kann. Gewöhnungsbedürftig ist allerdings das Aussehen, wenn man damit durch die Hütte läuft, aber man will ja auch keinen Schönheitspreis gewinnen. Ich habe den Schlafsack in der Taille einfach zusammen geknotet, statt den Kordelzug hoch zu ziehen.

Bester Schlafsack ever!

Hatte schon den normalen Microliner, hab mir jetzt aber noch den kleineren in Stretch gegönnt! Und die Lieferung war sowieso unschlagbar ;-)
