Base Top Power Stretch®

(3 customer reviews)


The base top is your new wintertime best friend: a warm wicking under-layer to keep your core happy when everyone else is heading inside. It’s the no-one-thinks-about layering secret to staying warm on those days when you have to keep moving from getting chilled. And it’s temperature regulating fabric keeps you from overheating during full-intensity training sessions.

Made in Massachusetts, USA


Textile: Polartec® Power Stretch® single velour

  • also used in performance tights, undertop, and winter bra lining.
  • content: 49% Poly, 38% Nylon, 13% Spandex
  • strengths: insulation, abrasion resistance, moisture transfer, wind resistance, light weight and water shedding
  • This textile was developed to maximize the garment’s range of motion. The majority of elastic base materials can stretch during movement, but lack the tensile strength to recover their original shape and eventually become permanently damaged. By utilizing elastic fibers with enhanced resilience in our stretch construction we made a performance-fit base fabric that can handle the pressure of demanding physical activities.

Construction techniques:

  • Flatlock
  • Overlock
  • Top Stitch finishing

The perfect add-on layer to get me through New England’s 20+ degree temperature swings between the early morning and evening ends of my bike commute. Just warm enough, and minimum bulk in my bag when not being worn.

Along with being a 4 season cyclist, I’m also an ironworker. Understanding the importance of multi layering I decided to give the Base Top a try as a first layer. I am convinced that this is the best base layer I’ve tried. Even at sub zero temperatures I can break a sweat. The moisture wicking fabric took care of that. I was also impressed at the very affordable price. C.J.

I’m enjoying this base layer every day this winter. With temps in the single digits almost every day for the past couple of weeks here in Massachusetts, the Base Top Power Stretch, combined with the Elite Half Zip Power Dry, keep my core warm and dry whether I’m fatbiking or taking a nap. I’ll also add my Arm Warmers Power Stretch when the windchill really dips…
