Zpacks オクタフリースハット

I’ve worn it on windy ridgelines down to freezing and my ears stayed warm the whole time—the doubled fleece over the top makes a real difference. It packs down so small I forget it’s in my jacket pocket, and it’s honestly the lightest layer I own.

Took this hat on a chilly morning hike and was surprised how warm it stayed even with just a single layer of fleece. The lightweight design means it packs down to nothing in my jacket pocket, perfect for ultralight trips.

Finally a fleece beanie that isn't bulky—the ultralight design means I barely notice it in my pack, but it kept my ears warm on a gusty ridge. The double layer adds just enough insulation without making my head sweat.
