Arc'teryx Cerium SL Vest - Men's

Exceptional minimalism.

The Arc'teryx Cerium series is composed of streamlined down insulators, and the SL moniker stands for super light, so you can probably figure out for yourself what the Cerium SL Men's Vest is all about. With a face fabric made of wind-blocking Arato 7 polyester and coated with a water-repellent DWR finish, the Cerium SL is as functional a fall outer layer as it is a winter midlayer and is filled with a strategic combination of 850-fill goose down and Coreloft synthetic insulation to keep you warm, reduce weight, and provide all-weather functionality. The down is concentrated around your core to provide increased warmth, and the Coreloft is located in areas that are more prone to getting wet, so you don't lose insulating power if you get caught in a quick storm.

Coreloft isn't as light or packable as down, but the Cerium SL still weighs a miraculous 4.1oz and stuffs easily into the integrated stuff sack, so it will never slow you down or feel bulky. An elasticized rear hem helps keep snow and drafts from invading your inner layers, and the low-profile collar is finished with a soft chin guard to protect your skin when you burrow down against the cold.

Great Layering Piece

  • Familiarity: I've put it through the wringer
  • Fit: True to size
  • Size Bought: Medium

This super lightweight athletic cut vest is the perfect layering piece given its efficient, minimalist styling. I've worn it a ton this winter and it's held up great. Works and looks great as outerwear too. 38" chest, 5'7" and 150 lbs, and a medium was spot on.

Perfect Fit

  • Familiarity: I've used it once or twice and have initial impressions
  • Fit: True to size
  • Size Bought: Large

This vest is exactly what i was looking for. I am 6'1 175 with a 42 inch chest and this vest fits me perfectly. I can barely tell im wearing anything over my base layer but i am much warmer. There is so little material that the vest is almost instantly warm when i put it on. I love the simplicity and the solitary napoleon pocket. The construction is flawless.
Packed size shown in picture. I'm guessing this is a 1L stuff sack.
