I wonder how does it compare in terms of abrasion with the Atom LT. I had one which started showing some wear and tear after a year of constant use.
I also wonder how small is smaller than the Atom? I have an Atom LT in XS which fits perfectly, but now that I’m searching to buy a Proton I wonder if the XS would ever fit.
Thanks
]]>Hi there, both jackets are insulated using Coreloft™ insulation although the Atom AR has a higher density of the insulation which may make it slightly warmer. As for holding up to winds, both are wind resistant and designed to be breathable mid layers that will perform similarly in windy conditions.
]]>You might want to go with a large for the Proton. My coworker Mark is 5’11 / 170 lbs and he says the medium fits him OK. However, I always just suggest getting the Alti membership for free returns + extra 5% off and order both so you can see which one fits the best.
]]>The Proton AR uses the Fortius face fabric and so is more are air permeable (think winter air conditioning, when you need it most). The insulation is also the Coreloft Continuous which has a consistent amount of insulation per centimeter squared. Finally the fit is slightly snugger than a Atom AR.
