I love just about everything about this beanie: - It's really light weight and packs down well. It's much smaller than a traditional knit or fleece stocking cap. - It's snug without feeling constrictive. - The Ascendant combination of Pertex + Polartech alpha keeps your head and ears warm, but not hot. - When there's a little precipitation, it helps keep your head dry better than a fabric beanie. - I use it for morning runs under 30 degrees mostly. I wasn't sure what I would think about this beanie but it's just about perfect.
