Atom Ar Vs Proton Ar. Only thing the Atom line has on them is wind resistance IMO which probably isnt the point. The insulation is also the Coreloft Continuous which has a consistent amount of insulation per centimeter squared. Under standard conditions it is the lightest metal and the lightest solid element. Proton AR felt the most rugged and breathable while Cerium definitely felt the least rugged.
Argon is a chemical element with the symbol Ar and atomic number 18. The inner material doesnt feel great next to the skin but aside from that the Proton AR is a comfortable thing to wear with good articulation around the elbows and underarms.

The chemical symbol for Lithium is Li. The Thorium AR should be easily warmer than the Atom AR.
Atom AR is warmth focused and the Proton LT is breathability focused.
This makes up one of the biggest differences between the two models. The inner material doesnt feel great next to the skin but aside from that the Proton AR is a comfortable thing to wear with good articulation around the elbows and underarms. Like all alkali metals lithium is highly reactive and flammable and is stored in mineral oil. That said the Atom AR will be much more breathable and less prone to overheating. Correct me if Im wrong but London must be freezing now haha. HttpsgeniusAtomAR Arcteryx Atom LT light.
