Cycling Base Layers

Don't let those fickle weather days get in your way.

This is why we ensure that our cycling base layers are lightweight, breathable, and specially designed to keep you dry and free from common irritants, in addition to their other features.

Whichever piece you choose from this collection, you’re sure to get one that will help regulate body temperature and wick away moisture so you stay focused on your ride and not discomfort.

So, next time you hit the trails or hop on your indoor trainer, throw on a base layer to make your ride experiences even better.

What Are Cycling Base Layers?

Cycling base layers are essential garments you can wear under your jersey or jacket—or even on their own if conditions call for them.

They help manage moisture when you’re getting a bit too sweaty, and they add extra warmth when it’s not quite jacket weather (but a bit too chilly for a single jersey).

• Insulation—On cooler days, a base layer provides added warmth without bulk, so you stay cosy while still being able to pedal freely.
• Moisture Management – Made from moisture-wicking fabrics, these base layers keep sweat from building up, so you can stay comfortable and focused on the ride instead of getting sweaty and slippery.

Sigr's cycling base layers are available in classic black and white. Both are thoughtfully designed to fit comfortably on male and female cyclists alike.

Experience the Difference with Sigr Cycling Base Layers for Men and Women

Sigr’s cycling base layers are made for cyclists who need reliable, comfortable pieces of gear. We blend quality materials with smart functionality to keep you feeling good and performing well on every ride.

Here are the qualities that set Sigr base layers apart.

1. Insulation and Versatility

Whether it's a crisp morning ride or a sweaty indoor training session, Sigr’s base layers have your back. They add just the right amount of warmth when it’s too cool for a jersey but not cold enough for a full jacket.

And when you’re training indoors, the moisture-wicking fabric can keep you in the zone, no matter how sweaty you get.

2. Breathable Comfort

Comfort on the bike isn’t optional—it’s essential. Sigr’s base layers are built with this in mind.

The mesh rear panel doesn’t just look good; it also does its job well.

It traps just the right amount of air to keep you warm under your jersey while still allowing heat to escape when you start to feel the burn.

3. Lightweight and Quick-Drying

No cyclist wants to be weighed down by heavy, damp clothing. That is why Sigr’s base layers are made from a lightweight fabric that dries quickly, even after the most intense rides.

Whether climbing steep hills or pushing your limits in a sprint, you will appreciate how these layers effectively manage moisture and keep you feeling light and agile.

4. Tailored Fit for Men and Women

Sigr's cycling base layers are thoughtfully designed to comfortably fit both men's and women's bodies.

Our attention to detail ensures that every seam and panel is placed strategically to provide a snug yet unrestricted fit.

No distractions. With these layers, the only things that matter are you and your ride.

5. Commitment to Sustainability

As a cyclist, you’re already doing your bit for the planet—and we’re right here with you.

Some of Sigr’s sustainability efforts include using eco-friendly materials, carbon-neutral shipping, and partnering with Shopify’s Planet program.

This ensures that every piece of gear you get from us is a chance to make a difference.

Frequently Asked Questions

• What Is the Difference Between a Base Layer and a Regular T-Shirt?

  Unlike a regular T-shirt, a base layer acts as a “second skin.” It is designed to be tight-fitting yet breathable, with sweat-wicking abilities, insulation, and temperature regulation features. Regular T-shirts, meanwhile, are primarily made for ordinary comfort and style and would not be ideal for use when cycling.

• Can You Wear a Cycling Base Layer in Warm Weather?

  Yes, base layers can be worn in warm weather, too. The high-tech fabrics used in base layers wick off sweat, regulate body temperature, and help keep you cool and comfortable even on hot days.

• How Should Cycling Base Layers Fit?

  Base layers should fit snugly against your skin for optimal performance and comfort. Choose a lighter-weight base layer for warm weather and a heavier-weight one for cold weather.You can check Sigr’s Product Sizing Guide for more.

  1. Wash base layers after each use with a gentle detergent.
