Mark – for me the Bindi is a summer headlamp for incidental light in camp, reading in my shelter, etc. I prefer a handheld light like the Zebra as well for winter and nighttime hiking. Used in this context, I haven’t yet found any battery issues for the Bindi, and find that it lasts for 3-5 nights for my normal summer routines, depending on how late I get into camp and how much I read/write at night.
I haven’t found any solar chargers that I really like. I’m banking on the arrival of thin(ner) film panels in 2020 in small (5-7W) sizes, but larger sizes than the little mW panels on the side of small battery banks. Hoping we can get a 5W panel at 6 oz or less…
The Shell – I’ve ripped it and patched it a couple of times now. It’s pretty durable, but not immune to tearing/holes in sharp brush. It’s more durable than the Vertice, that fabric is a little more on the fragile side – only 7d. My first test with this jacket in light brush didn’t go awesome. That aside, it’d be a great thru-hiker coat I suppose, it’s very breathable.
The Arc’teryx Zeta FL I reviewed is proving to be quite a bit more durable than the Vertice.
