Reasons NOT to buy:

User Reviews

  • Expensive.
  • Should be better manufactured for the price.
  • The cuff seam separated.
  • Even though the Atom LT is such a popular jacket, I don’t get it – the fit and construction don’t justify the price or reputation.
  • Front pockets don’t provide a lot of space for your hands.
  • If you get the hooded version, be aware that the hood is built to fit over a helmet so it’s big.

Expert Reviews

  • It can be compressed but not incredibly well.
  • Not as breathable as the Patagonia Nano Air.
  • The chest pocket sits low and felt more like a stomach pocket.
  • Too short in the torso.


The Arc’teryx Atom LT Hooded Insulated Jacket is warm, breathable and provides some protection from wind and precipitation. It’s functionality is ideal for strenuous cold weather activities and its style allows it to be worn around town.
