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.

Lightweight, compact and comfortable, but durable enough at the bottom

I needed some waterproof pants as light and compact as possible, but still durable enough, especially at the bottom of the legs where hiking ones usually fail. Those fits the bills perfectly, are very easy to put on and comfortable thanks to the stretch (and thanks to the stretch, they do not need to be overly baggy). Tested in rain and snow for hours. I will definitely buy the jacket once it is available in Europe.

Love the pants and their packability. I will be taking them with me on our ride of Ireland, the Isle of Man and the 2024 Malle Rally in Scotland & England. Space and weight are a big deal and given the unpredictability of the weather in Great Britain and Ireland, I'm sure they will come in handy.


Its unreal how small I can pack these for how tough the lower, essential areas of durability are. They don't pack as small as my lightweight backpacking waterproof pants but I doubt they would fare well against highway speeds, much less a hot engine or a crash! Plus, they fit over the massive uppers of my Leatt enduro boots perfectly. 10/10

Light and packable

Size S is at the limit over MM Woodsman Enduro OTB size S that fits perfect. Did not tried yet with knee brace but seems at the limit also. The stretch fabric is a nice feature. Let’s see them in the rain and over o long period of time from durability point of view - the material is quite thin. I give them five start but 4.5 is closer to reality.

Barfly Microshell Overpant

As a commuter who travels on gravel and dirt roads I wear these overpants everyday to keep the elements off of my pants. Excellently functional overpant that is wearing well. After a month or so of use I would like to see a pocket accessible from the outside, similar to the Rak overpant and a more secure pant leg. Having an adjustable pant leg bottom will help keep my regular pants cuffs dry on wet days and dust free on the dry days.
