Arc'teryx Atom LT Insulated Vest - Men's


Atom LT Insulated Vest

Get your daily dose of core warmth with the superlight Arc'teryx Atom LT Insulated Vest. Its Coreloft insulation makes the Atom excellent for shoulder-season hiking, and you'll definitely appreciate its warmth when your ski jacket just isn't cutting it alone on winter's coldest days. Arc'teryx made the Atom's shell out of a durable Tyono fabric that has a DWR coating for water-resistant protection in the elements. Breathable, stretchy fleece makes the sides air-permeable and opens up your range of motion, while its compressible and packable design lets you toss it in your pack if the weather changes.

  • Insulated vest ideal for anything active when it's cold
  • Coreloft insulation stays warm when wet
  • Stretchy fleece side panels wick moisture and breathe well
  • DWR-treated shell sheds snowflakes and light moisture
  • Multiple pockets zipper shut for secure storage
  • No Slip Zip front zipper operates smoothly and reliably
  • Item #ARCZ969

Not slim fit

I returned this product before using it
Runs large
Size Bought
5` 9"
210 lbs

I ordered a large, which is exactly the same vest I ordered last year that fitted well. The new one is HUGE. I wonder if it was incorrectly labeled from a big-and-tall version. Needless to say, I was disappointed and initiated a return. I hope I get a full refund.

Not sure a change in sizing warrants a 2 star review... I'm 6'2 185 and the medium fits great. Also if you ordered from Backcountry then of course you'll get a full refund, I wouldn't steer people away from a great product just because it didn't fit you specifically.

Very comfortable vest!

Ordered the SL and LT. I am 5’10”, 170 pounds, 40” chest and 30” waist. Both of these vests are more slim fit which is ideal. That said the SL is more snug in the belly and is considerably lighter and more flimsy feeling. Between the 2 vests I do prefer the LT. Zippers, neck fleece, tougher material - just more substantial feeling but still light weight. Both vests serve a purpose but the LT I prefer.
