Synthetic fiber - Sleeping bag test 2018 Alpine
"Test impression: The Grüezi Bag, like all Grüezi Bag sleeping bags, is a bit different. The zipper runs differently (on the top), which turns out to be quite practical in use because it's easy to operate. However, if you want to stick your feet out at the bottom (as described by the manufacturer), you have to open the zipper quite wide to avoid feeling cramped. The sleeping bag is completely PFC-free. When sleeping, you notice that the Grüezi Bag has a quite good sleeping climate and you sweat very little. The insulation is good for the weight!
Conclusion: A slightly different sleeping bag with good materials, which you'll notice when you sleep. The very light and fluffy insulation material is good, and the Synpod Island's insulation is good for its weight. The features are basic.
+ good materials, good sleeping environment
- RV course takes some getting used to
