Gear Guide: Best Base Layers

Updated February, 2018

There are two main reasons that riders choose to wear a base layer when riding and both are related to the climate in which they will be riding. The most popular reason for a base layer is to fend off colder temperatures. This is a sign of a truly dedicated rider, as the casual rider simply puts their bike in storage when the weather is not cooperating.

But for those who truly “live to ride” cold weather is not so much a deterrent as it is a nuisance. A good base layer provides a thermal property which will help to trap your body heat and keep you warm during your ride. Some base layer gear is also designed to block the wind which is also a great help in maintaining your body temperature.

The other occasion for a base layer is at the opposite end of the temperature spectrum. This is the gear that is designed to wick moisture away from your body and allow your internal cooling system to function more efficiently. This feature also helps with rider comfort as you are not dripping wet and feel like you are sitting in a puddle.

Again, it’s the dedicated rider who is interested in this gear, as the casual riders are not out when the temps crack the 100-degree mark. An additional benefit of warm weather base gear is when it’s time to peel off your jacket and pants. The wicking capability helps to keep your skin dry and allows for a much easier removal of other gear. You might also notice that heat base layer gear will reduce the likelihood of heat rash or abrasions due to wet clothing rubbing your skin as you move.

Base Layer Buyers Guide

Nothing can suck the joy out of a ride like being uncomfortable. And in some cases, such as in extreme cold or heat, discomfort can actually distract and impair a riders ability to perform safety. The issues faced when riding in a cold climate are pretty obvious. A riders hands and feet can become numb making it impossible to efficiently and safely operate the bike.

In extreme cases, the cold can also cause lack of concentration and cognitive issues as the body naturally forces more blood flow to the extremities and organs, which means less blood flow to the brain, in an effort to keep them warm and functioning.

In most cases, discomfort becomes a factor before any other life-threatening factors or cognitive impairment and the rider seeks shelter. But an equally serious problem can be riding in hot weather. And this is not as likely to force a rider to seek shelter so the result can be more catastrophic.

Dehydration in excess of just 2% body mass is known to inhibit short-term memory, attention, concentration, coordination and motor function speed. All of which are critical to safely operating a motorcycle.

In an effort to eliminate these potentially serious events more riders are relying on base layers to help keep their body at an optimal temperature when riding. Not only does this greatly increase rider enjoyment but it can also be the key to avoiding some potentially deadly situations. Our guide covers some of the more popular base layers for addressing both the heat and the cold.

The Winners
In Detail

Best Overall
Klim Aggressor

Klim Aggressor

Buy: Revzilla | Amazon
Price: $49.99 – $79.99

The Klim Aggressor base layer series offers both shirts and pants of different thermal levels to meet a variety of different environments.

Though the descriptions are less than scientific, Klim defines 1.0 as good for chilly weather, 2.0 for cold weather and the 3.0 for frigid conditions. So riders can select their favorite layer based on their ability to tolerate cold and their desired level of comfort.

  • The basic construction of all of the base layer items is the same and offers a gridded material that is designed to trap body heat.
  • The material is also low-profile to reduce bulk and allow for full range of motion.
  • The combination of polyester and spandex provide a custom fit and feel smooth to the skin.
  • Additional points of interest include the anti-microbial benefits, moisture wicking, high breathability, and capability to dry quickly.

All of these features are important in cold climates as the fabric which does not pull moisture away from the skin will feel damp and cold very quickly.

The cost of each piece of the Aggressor base layer gear ranges from about $50 – $80 which is right in line with most other types of base layer gear. It is also a bonus that riders can purchase different thermal levels for the pants and shirt depending on their personal needs and comfort.

For these great features, we are selecting the Klim Aggressor as the Best Overall Base Layer.

Best Value
Firstgear Winter Base Layer

Firstgear Winter Base Layer

Buy: Revzilla | Amazon
Price: $69.95

The Firstgear Winter Base Layer offers both pants and shirts, which have a ¼ zip front, but there is only a single thermal level for this gear. An added benefit from Firstgear is that the outer shell is nylon and provides greater wind and water resistance than brands made with polyester.

The 7% spandex inner lining provides a snug fit for warmth and eliminates rubbing or chaffing. This base layer is also designed to be very breathable and to wick moisture away from the skin.

The Firstgear Winter Base Layer gear does not provide my options or choices for riders but the price is definitely more reasonable than some other choices. At just $69.95 per piece, we are selecting the Firstgear Winter Base layer as the Best Value.

Dainese D-Core Base Layer Suit

Dainese D-Core Suit

Buy: Revzilla | Amazon
Price: $129.99

The Dainese D-Core base layer suit provides a lot of benefits at a very reasonable price. In most cases, the Dainese products are superior to other brands but the cost is also a lot more than other options. In this case, the D-Core suit is actually very reasonably priced as compared to other drysuits.

  • The D-Core is made of environmentally friendly Dryarn, Polyamide, and Elastane which are all 100% recyclable.
  • The seamless design provides maximum comfort and the Air Grid and active moisture management help to keep you cool and dry.
  • The suit is also treated to provide a layer for the skin which is bacteriostatic, hypoallergenic and offers anti-odor protection.

But the most unusual feature of this suit is that it offers Armor Pad for additional safety and comfort in potential contact areas. These areas are also constructed to be abrasion resistant, tear resistant and to be pull resistant.

At around $130 the D-Core suit cost is very similar to the cost of other suits or other shirt and pant base layer combos used to combat overheating issues. But the added features of padding and abrasion protection make the Dainese D-Core Dry Suit our selection for the Best Fully Loaded Base Layer.
