The Spark Pro -1 was the perfect bag for a recent shoulder season trip to NZ where low temps were expected but the grams mattered
After tossing up between this and a quilt; I went for the sleeping bag as it was rated to lowered temps, lighter and there is no stuffing around with straps and clips and drafts. The free flow zip system worked a treat as I was able to sit up and do admin in the tent without getting cold.
Would absolutely recommend this over a quilt any day!
This zip system was a game changer!!
Very light and comfortable, should of bought one years ago.
Very handy clear bottle to keep an eye on my water consumption
Light, inexpensive, easy
