Barfly Microshell Overpant

Barfly Microshell Overpant


The Barfly Microshell 3-Layer Overpant is our lightest waterproof pant. It blends 30K/30K waterproof / breathable 2-way stretch 20D Nylon with 20K/20k 4-way stretch 160D Nylon reinforced knees and lower leg to balance weight and packability with durability where it counts. The full side-zip overpant design allows you to change as quickly as the weather, and when not in use, the Barfly stuffs into an integrated drop pocket to easily stash away until you need it. 

Combine with the matching Barfly Jacket and rider-favorite Woodsman Pant to create a versatile multi-season layering system.

Deployed, it's a lightweight 635 gram (22.4oz), stretchy, 3-layer waterproof / breathable overpant.  When stashed away into its integrated drop pocket, it prioritizes pack space, fitting easily into your backpack or tail bag, so it's there when you need it from day rides with questionable weather to extended ADV trips.

Use these pants to add waterproof protection and extend the performance range of our Woodman, Kiger, or Surveyor Pants or any other non-waterproof pants you have. The full zip overpant design allows you to get them on and off quickly, and the silicone gripper elastic cuffs fit securely around the boot to seal out the wind and weather.

Even fair-weather trips have their moments. Bring along some reassurance with the Barfly Microshell Pant.

Barfly pants

Have yet to get out on a ride with the Barfly pants. However, impressed with how they fit when simply sitting on my bike in the garage. As a slight improvement could have them to be about 2 inches longer so the bottom of the pant is just above my ankle when I am sitting. However, I wear tall boots so it works. Great material selection!

Great Lightweight Option

I used to use my backpacking shells back in the day for emergency rain protection but destroyed enough rain pants and a couple jackets that I gave up on the ultralight options. These Barfly pants are everything that I wished I had years ago. They have extra protection in the lower legs where needed and they also have a stretch material that makes mounting and dismounting the bike much easier and protects the crotch from tearing open. I also dig how they fit over my Tech 7 boots with ease. I wore them over my Woodsman pants as a wind layer and they added the perfect amount of warmth. I haven't used them in a rain storm yet, but I live in Washington, so that day will come soon enough. I wouldn't use these as full-time pants or go crashing through sticker bushes with them, but they are perfect for stashing in your bag for the inevitable rain events.
