Winner-winner-chicken-dinner – the women’s wind and water-resistant Bontrager old man winter soft-shell fat bike pants are made for winter cycling and fat biking in the snow.

Thank you to Elliott Smith, fat bike girl in Ontario, Canada, for her review:

The pants are a relaxed fit, so there is room for layering without bunching or feeling constricted. In my experience, the size chart on the Trek product page is misleading for Bontrager’s relaxed fit clothing, like these pants and their mountain bike line. For example, I would say the L (10-12) fits more like a 12-14. Bontrager’s 30-day comfort guarantee comes in handy if you can’t try them on and have to order them in.

My favourite part of these pants? All the pockets and their zipper closures. The pockets on the upper thigh mean I can keep my phone handy when it’s warm enough and it doesn’t interfere with pedaling. One of the hand pockets has a little microfleece inner pocket that keeps small items close. It’s great for a key, or a presta adapter, so you’re not fishing around in a panic when you need that one little thing you didn’t want to lose.

I also like the removable gaiters, as I often remove them when biking, but put them back in when snowshoeing (multi-purpose pants!). I find that the zipper and button combo on the cuff cinches tight enough around my boots for most rides. I liked them so much I bought them in both colourways. Definitely recommend, although they are not inexpensive from $150 – $210 on the Trek site.

Zipper and snap fits over my Keen winter boots and there is an internal gusset for protection when not wearing gaiters.


Note from Fat Bike Girl: I’ve had mine for an entire season and they have been very durable so far. I’m notoriously hard on equipment and have bushwhacked over downed trees and not torn them. However I am a little concerned about them wearing through on the booty as that area has become lighter from rubbing on my saddle.  If you go with the grey colourway then you likely won’t notice any posterior wear.

These are a shell pant and I wear the Velocio Zero Bib for the base layer.

I appreciate the attention to detail in the design.  For instance the ankle cuff protection is taller on the right leg than the left for extra durability on the chain side. And big kudos to Bontrager for making these in a women’s version that is not a watered-down version of the men’s!

What would we change?  At this time they don’t come in tall sizes.  Also, they could use a little more wind protection on the thighs and extend the front wind protection down to the knees to cover the entire thigh.  I wear a thermal wind-proof bib underneath but my thighs still get cold.  This can be mitigated by putting a hand warmer in the front thigh pocket.

Is is WHEELIE WORTH it: Yay!
