Whether you trying to warm up in the tent after a day of touring or need an extra layer for frigid exploits, the Atom LT Pant is ready to wrap you in the comfort of Coreloft. What's Coreloft you might ask? Coreloft is Arc'teryx's go-to synthetic insulation and the the Atom LT pants come with 60g of this miraculous non-woven insulator to keep you warm even when you stop moving. Synthetic insulation is preferable in winter environs because it can still provide warmth when wet. Additionally, the Atom LT pants are a favorite amongst back-country enthusiasts because they pack down incredibly small (into its own pocket actually) and tip the scales at less than 12 ounces. Just because you need warmth doesn't mean you want to take off boots, so Arc'teryx included full length zippers allowing the pants to be taken on and off without worrying about footwear. To complete the package Arc'teryx outfitted these toasty leg layers with a Tinthan shell and DWR coating, resisting light precipitation and adding fabric strength. Cold legs suck, so keep your extremities warm and happy with incredibly packable lightweight synthetic technology.
  • Light, soft face fabric has DWR finish to repel moisture and good air permeability for active use
  • Warm and resilient synthetic Coreloft insulation
  • Fully articulated knees and seat for optimal range of motion
  • Fully separating side zippers with laminated windflap allow for easy removal over boots and crampons
  • Stuffs into its own hanging pocket for easy storage
