The Helly Hansen LIFALOFT Hooded Jacket rates high for insulation and lightness, so it holds real warmth without adding weight to a pack or a layering system. An elastic hood stays put on its own, without a drawcord or hardware to fuss with, and windproof, breathable construction keeps it comfortable moving through cold air. It's built to insulate first, with a DWR finish handling incidental moisture rather than standing in for a full rain shell. What Our Gearhead(R) Experts Are Saying:"I've worn this through wind and genuinely cold air and stayed warm the whole time, but the moment real rain started, I reached for a shell over it. Knowing exactly what a jacket is built for is worth more than a jacket that claims to do everything and does none of it especially well."
