You never know when your day hike will extend past sunset, so be sure to keep Petzl's Actic Core Headlamp in you backpack. The Actic will light up snowy trails in front of you during dawn patrols, and it'll be there at night when you're heading back home after a dusk hike. The mixed beam uses flat and concentrated lighting to give you clarity when you're running. Petzl's rechargeable battery makes sure you don't have to purchase batteries every season.
