Barfly Microshell Jacket

Barfly Microshell Jacket


The Barfly Microshell Jacket is our lightest waterproof layer at 340 grams (12oz). Streamlined for packability, we prioritize simplicity and weather protection to deliver a highly packable, high-performance 3-layer 30k / 30K waterproof / breathable shell that's easy to find room for.

Combine with the matching Barfly Overpant and insulated Jackaloft or Ectotherm Jacket to create a versatile multi-season layering system that packs down small.


This lightweight 3-layer 30K / 30K waterproof / breathable shell features 20D Nylon stretch fabric that allows for unimpeded movement while riding and ease of layering over armor. Seal out the weather by tightening the adjustable elastic cuffs and drawcord hem. To combat the flap often associated with lightweight materials at higher speeds, cinch up the anti-flap adjustment hidden in the chest pocket. It also boasts a removable, single-adjust hood. Remove the hood when riding, or wear it under your helmet on nasty days for even more coverage. When not in use, the Barfly stuffs into its chest pocket to easily stash away until you need it. Even fair-weather trips have their moments; bring along some reassurance with the Barfly Microshell Jacket and matching Barfly Overpant.

Light is Right

I recently wore the Barfly Jacket during the Southern CABDR and I really enjoyed how light the jacket was and how versatile it is. I was in a range of temperatures from 38˚ to 76˚ and I wore the jacket everyday either as an outer-shell or as a layering piece (I had a heavier jacket with me). Because the Barfly jacket is lightweight I was comfortable wearing it when the temperatures climbed and because it's so thin it was a great layer when I wore a more robust jacket for added protection.

The only reason I didn't give it 5 stars, and this is personal preference, is I would like the shoulders down to the elbows to have a more durable layer or a fabric like the Barfly pant does. I was nervous that if I fell I would tear the arm of the jacket. Luckily I didn't have to find out, but I would love to see this area reenforced. That aside, I highly recommend the Barfly jacket and pants. They're both great.

Worth every penny

My lightest waterproof layer now, almost feels like paper. Easy and quick to wear & packs small on a rainy day. Love the extra protection of hood. ❤️
