Women’s Winter Cycling Pants for Fat Biking

Stay warm, ride happy. Part II.

by | Sep 18, 2021 | Gear | 6 comments

Drumroll please, here is a list of women’s winter cycling pants that were recommended by women fat bikers. Also included at the end are a few men’s-only pants (also recommended by women).

Please note, you don’t need an expensive pair of cycling-specific pants for winter fat biking. If you have a ski kit, then you have a fat bike kit.  

For years I wore my Swix cross-country ski pants for fat biking.  They have a wind-proof front, articulated knees, side zips, and are stretchy.  Under those I wore either a light base layer or my cycling bibs.

My system worked well but at some point I became envious of the dudes and their Club Ride Fat Jack pants.  I bought a pair, which I like – except I roll them up because they are men’s (and only made in a men’s version).  A few years later I found a couple of pants made just for women.

1. Bontrager OMW Women’s Softshell Fat Bike Pant 

I’ve had these for a year now and I LOVE them.  They thought of every detail with the design.  I got tired of “making do” with other pants that didn’t quite work and I’m glad I splurged on these.  The waist comes up a little higher in the back than most; the zippered cuffs and snaps easily accommodate a few different pairs of boots; I love the adjustable waist with the built in belt; and my favorite part is the zippered pockets on the front of the thighs.  I put chemical hand warmers in them when my thighs get cold on the downhill.  They are a roomy fit, which is nice because I wear my 3/4 length wind-front bibs underneath.

In addition to this, low profile waist adjustment, zipped expanding ankle closure and knee articulation all ensure high functionality for the mountains. Light and highly packable, a small stuff sack aids easy storage in a pack or clipped to harness.
