Best synthetic outerwear - Arc'teryx Proton LT Hoody - Men's

Atom LT has durability problems, so it is difficult to wear it in the mountains.

Proton is more durable, lighter and warmer than atom at the same time.

Gold is also too luxurious in color gold.

If you ask me to buy either Atom or Proton,

I'm going to buy a Proton.

Because I am satisfied with both other management and mountain climbing.
