The only thing I regretted forgetting was waterproof rain pants. Wasn’t really a big deal in the end but I would have made things a little easier a few of the days. 😅 btw everyone should go to Iceland.
Interesting video... But no bag for the hiking boots? What about for the flight back when they are all muddy? Also, if the toiletry kit is at the bottom of the backpack isn't that a hassle when going through airport security flying from the USA to Iceland? Finally, would have been interesting to actually _see_ what clothes he carries in the packing cube. Not just hear him say it.
I think the single most important item I took to brave Icelandic winter was a set of waterproof hiking boots. A tight second was merino wool socks. Only slightly behind that was a Gore-Tex jacket, given the amount of precipitation I needed to keep out, and perspiration I needed to be allowed out during hikes.
