Product Description

All Spark sleeping bags are characterised by their ultra-light weight, minimal packing size and excellent thermal performance. The Spark SpII features vertical breast chambers that are stitched throughout for extra down and reduced cold bridging. Other continuous horizontal chambers in the foot area minimize the weight. A half-sided zipper with two sliders makes a comfortable entrance possible and serves for additional ventilation. The optimized sizes of the Spark sleeping bags offer more space on shoulders and hips. The integrated zipper channel prevents heat loss and the SpII comes with a heat collar for added protection.

Ultra Dry Down
UltraDry Down is a PFC-free water-repellant treatment applied to the down used in all Sea to Summit sleeping bags. UltraDry Down retains over 60 % more loft, absorbs 30 % less moisture and dries out 60 % faster when compared to untreated down – which means the down will insulate better even in damp conditions. The treatment also inhibits bacterial growth, making your bag last longer. UltraDry Down treatment is an environmentally friendly application.

Hält was es verspricht. Klasse 1A Produkt
Translated from German To the original

The sleeping bag is extremely light and the pack size is as stated. The material feels very comfortable and keeps you warm very well. (3 days of continuous use in the rain => no problems with moisture) Repacking in the case is a bit tedious, but this is gladly accepted for the light weight and small pack size. Great product !!! I can only recommend.

Der Schlafsack ist extrem leicht und das Packmaß ist wie angegeben. Das Material fühlt sich sehr angenehm an und hält sehr gut warm. (3 Tage Dauereinsatz bei Regen => Keine Probleme mit Feuchtigkeit) Das Wiederverpacken in die Hülle ist etwas mühselig, jedoch nimmt man dies für das leichte Gewicht und das kleine Packmaß doch gerne in Kauf. Klasse Produkt !!! Kann ich nur weiterempfehlen.
