great sleeping bag for warmer temperatures
This bag is well made and packs easily into a small sack. I often use it for sleeping at my workplace and the cube storage bag is perfect for my office locker! So far I have only used it a 70F and I am very comfortable sleeping with the zipper down. I like the look and feel of it. I generally only use sleeping bags down to about 20F above their rating and this feel like I would be comfortable down to about 50F zipped up.

Cheap Zipper / Doesn't Breath
This only gets a second star because it actually is really light. The rest is not worth the money. The zipper separates to easily and you have to fumble to fix it at night in the tent. The material is very strange. It doesn't really have any breathability. Even if your not too hot your body moisture seems to stay in the bag, so it feels like you are sleeping in a gargage bag.

PONTO POSITIVO: O saco é realmente leve, isso é o maior ponto positivo do produto, macio, aquece e é super compacto na hora de colocar na bolsa pra transporte. PONTO NEGATIVO: com o uso ele vai soltando algumas plumas, após acordar em todas as vezes que utilizei, achei plumas na minha roupa, o zíper precisa de cuidado para abrir e fechar, caso contrário ele pode pegar no tecido. A cor clara é outra questão, se não tomar cuidado vai sujar muito rápido. Então pense nisso antes de comprar, se você pretende comprar um saco de dormir que dure a vida toda, talvez esse não seja o caso, acredito que ele vá durar por uns bons anos ainda mas a longo prazo não sei se vai reter tanto o calor devido a essa perca de pluma com o uso. Se optar por comprar, seja cuidadoso com o zíper, siga as instruções de armazenamento da marca para ajudar a prolongar a vida útil do saco e esteja ciente de que vai perder pluma e isso pode gerar pontos frio no saco de dormir e tem a questão da cor que é clara e suja fácil. Quanto ao tamanho, não recomendaria ele para uma pessoa maior de 180cm.

軽いのにしっかり暖かい でも暑い時にファスナーが下までではないので広げて掛けるだけが出来ないのがちょっと残念 軽量の為なので仕方がないのかな

Super leicht, kompakt und für mich warm genug bis ca. 6 Grad Außentemperatur (persönliche Empfindung!). Lässt sich gut und schnell in den kleinen Packsack für Unterwegs verstauen. Ansonsten ist für die längere Lagerung ein Schnellpacksack dabei, damit der Schlafsack nicht dauerhaft so stark komprimiert wird. Auf mehrwöchigen Fahrradreisen im Praxistest und ich bin super happy mit dem Teil.

Molto caldo e leggerissimo. Nella confezione e prevista una sacca areata per non rovinare la piuma interna

表面がさらっとしており、変な湿りが無いのが良いです。それと、大変軽量です。 獣臭が気になるとのレビューがありますが、私のは全くしません。個体差でもあるのでしょうか。
