Runderwear Base Layer Review

A great option alone for cool weather.

Breathable comfort for winter training

It’s been a mixed bag of trail running this winter, but for just about all of my runs, the Runderwear Long-sleeve Running Base Layer has been my friend. Layered up appropriately or just solo, there’s a ton of comfort with this one. Let’s start out with the woven fabric, which consists of 92% Polyamide and 8% Elastane (whatever that stuff is). So, that adds up to 100% soft and comfortable goodness.

Something that’s nice about this base layer is the overall length and fit. At 5’11” and 170 lbs, the size medium is a good fit, but not as snug as a typical base layer. If you want body-hugging snug, size down. As mentioned, the cut is great, not oversized and with long enough sleeves to actually use the reversible hand mitts in a pinch. Overall hem length is great too for added coverage.

Chafe-free no matter how you look at it.

More on the fabric… the woven material is seamlessly spun in the body for a seamless design. But, it’s not just a flat material, Runderwear has engineered dimple sections into the fabric at strategic locations down the middle of the back, sides and sleeves. The result is added moisture wicking and stretch for ultimate performance. Something that’s interesting here, however, is that while it always feels controlled and comfortable during and after a run, it does take some time to fully dry when hung on a hook.

Runderwear Base Layer - Hand Mitts

You can deploy the hand mitt for an impromptu puppet show or cold weather.

I love that the shirt is tag-free and it’s also great at controlling odors. I can wear it multiple times before a wash is absolutely necessary. This is a great base layer as the foundation of your running outfit during cold weather.

The Good

  • Soft next-to-skin
  • Moisture wicking built-in
  • Overall cut is great for proper coverage
  • Stays stink-free

The Bad

  • Moisture management is good, but it takes awhile to dry when hung up
  • I’d prefer thumb loops over the mini mitts

The Bottom Line: Runderwear Running Base Layer

As a cold-weather base layer, there’s little to complain about here. As a foundation piece, you can add the proper pieces to be warm enough or wear it alone on warmer days. Overall comfort is excellent and breathability is good.
