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.

Nice piece of gear

Not yet tester in the rain. Seem well thought out, but I'm a bit worried the zip in the left hand side will open once you sit on the bike. I would have been nice if you could 'lock' the zip in the fully closed position.

Comfortable Overpant

… and really rainproof


Amazing quality

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!
