Fantastic, far superior to the others I have tried

Klein aber fein
Das Ding ist echt warm. Ob als Zusatz in kalten Gebieten oder als Haupt Schlafsack in passenden Temperaturen. Kann man machen 👍 ich finde vor allem die Öffnung unten auch sehr gut, dann kann man doch auch mal bei Kälte raus und verschwendet nicht gleich die ganze Wärme :D die Größe(ist klein) und das Gewicht ist es mir auch Wert es mitzunehmen. Bei richtiger Kälte ist nicht zu spaßen.

Mi aspettavo di più
Ho utilizzato questo supporto per 7 giorni in un campo scout i primi di novembre '24 con una temperatura notturna esterna di 10°C circa ma molta umidità, zona VT. Utlizzata con sacco a pelo nuovo con temperatura comfort +5°C , tenda invernale e ben isolata. Premetto che ahimè sono una persona molto freddolosa,ma nonostante i doppi strati di intimo termico,pantaloni di pile,maglia di lana e maglia di pile la notte ho sempre avuto freddo. Il materiale si lega con gli altri tessuti per cui limita i movimenti. Pro:facile da piegare,compatto e leggero. Si lava bene in lavatrice e non stinge.Sicuramente lo userò nelle route estive al posto del sacco a pelo o sacco lenzuolo ma in inverno tutta questa differenza di comfort termico non l'ho vista. Peccato perché l'azienda ha sempre ottimi prodotti.

Fan-freakin-tastic!
Did not expect to like this thing since I have restless less and claustrophobia... BUT this is a wonderful piece of gear for my cooler backpacking trips.I have a sierra cloud10 down sleeping bag comfort to 25F, but we headed out for early Nov trip in upstate NY/CT border... temps down to upper 20s so didn't want to risk it. The liner didn't tangle around my legs, nice drawstring around my head and arm holes for functional access. Nice and toasty!!! Liner also served double duty as a leg warmer/blanket while making breakfast on a cold morning.Was skeptical at first, but so glad I bought this thing. Worth the extra ounces in the backpack!!

J'adore
Matériaux très doux, très agréables pour dormir, surtout si l'on utilise un duvet technique qui n’est pas très confortable habituellement. Une sensation de chaleur est aussi observée
