1 review on stability, e.g. "it's soft against my skin and nice and stable and supportive.".
In short
Good for
- Ultralight backpackers who want a pillow under 50 g
- Use inside a Big Agnes bag: it fits the bag's pillow pocket
- Back and side sleepers who want to tune firmness with a micro-adjust valve
Strengths
- 45 g and 0.30 L: about the size of an energy bar
- Offset I-beam construction keeps it stable under the head
- Micro-adjust valve for fine-tuning firmness
- Soft four-way stretch nylon; Advnture found it quiet
- Stuff sack included
Weaknesses
- Only 25 cm wide, about two-thirds the width of a home pillow (Advnture)
- Thin nylon cover without padding: firmer and less cosy than hybrid pillows
- Costly for its size
- Only one independent comfort test found, and none on durability
