In short
Good for
- Keeping rain off your face and glasses on wet walking days
- Under a hood or on its own in showers: 40 g
- A peak for sun and rain on spring and autumn wild camps
Strengths
- Fully waterproof 3L laminate, 20,000 mm hydrostatic head, fully seam taped (montane.com)
- Light at 40 g (montane.com and Ultralight Outdoor Gear)
- Stiffened, pre-curved peak keeps rain off the face
- Rear bungee adjustment for a quick fit change
- Recycled nylon shell face and backer
Weaknesses
- A peaked cap gives no ear cover or warmth
- Not insulated: it keeps rain off but gives no warmth
- One size, adjusted by bungee, so very large heads may find it tight
- No independent hands-on test found, so durability is untested
