Zerofit Base Layers Review [Ultimate, Move, Leggings, Hoodie]


When it comes to spending time outdoors in cold and windy conditions, having the right clothing is essential. Zerofit, a renowned Japanese-based company, offers a range of base layers that promise to meet the diverse needs of outdoor enthusiasts. In this review, we will take a closer look at Zerofit's Heatrub line, specifically the Ultimate and Move (Mock) base layers. We will also explore the Heatrub Move Hoodie and Leggings to provide a comprehensive overview of Zerofit's base layer offerings.

The Importance of Base Layers

Before diving into the specifics of Zerofit's base layers, it's important to understand the role of base layers in cold weather attire. Layering is a commonly recommended strategy to stay comfortable in varying temperatures. However, too many layers can make you feel bulky and restrict your movement. Additionally, excessive layering can lead to sweating and overheating. Zerofit aims to address these concerns by offering breathable, thin, and flexible base layers that provide warmth without compromising comfort.

Zerofit Heatrub Ultimate: The Perfect Baselayer

The Zerofit Heatrub Ultimate base layer stands out as an excellent choice for colder weather conditions. According to Zerofit, it offers twice the warmth of a sweater and up to five times the warmth of a standard baselayer, thanks to its high Clo rating. The Clo rating measures the thermal insulation of clothing, with higher values indicating greater insulation. To put it in perspective, a business suit provides 1 Clo of insulation, while Zerofit's Ultimate base layer boasts a Clo rating of 0.74.

Understanding the Clo Rating

To better understand the significance of the Clo rating, let's take a closer look at its implications. Without any clothing, a person experiences a Clo value of 0.1, which is equivalent to sitting comfortably in a 70-degree room with minimal air movement. Comparatively, a thick turtleneck long-sleeve sweater has a Clo rating of 0.37, and a parka typically has a Clo rating of 0.70. Zerofit's Ultimate base layer surpasses both of these ratings, making it an exceptional choice for colder temperatures.

Zerofit Heatrub Move [Mock]: Versatile and Comfortable

For milder weather conditions, the Zerofit Heatrub Move (Mock) base layer is an excellent option. It shares the same innovative materials as the Ultimate base layer but offers a lighter and more flexible design. The Move (Mock) base layer maintains optimal breathability, ensuring comfort even in relatively warmer temperatures. When the temperature ranges from the 40s and above, the Move (Mock) base layer proves to be an ideal choice.

A Comparison with Other Materials

While Zerofit claims that their base layers outperform traditional materials, it's important to consider the specifics of the comparison. Unfortunately, the exact material used in the comparison with the thick turtleneck long-sleeve sweater is not disclosed. However, users have reported a noticeable difference when switching between the Move (Mock) and Ultimate base layers, particularly in temperatures below freezing. Individual preferences, weather conditions, and activity levels play a role in determining the most suitable base layer for each person.

Choosing the Right Base Layer for Different Temperatures

Selecting the appropriate base layer depends on personal preferences and the prevailing weather conditions. Zerofit's Ultimate base layer provides superior warmth and is recommended for temperatures in the 30s and lower. On the other hand, the Move (Mock) base layer offers optimal comfort when temperatures are in the 40s and above. It's important to note that both base layers are meant to be worn under a lightly insulated winter jacket as the top layer.

Zerofit Heatrub Move Hoodie: Extra Warmth and Coverage

In addition to the base layers, Zerofit offers the Heatrub Move Hoodie. This pullover hoodie is constructed with the same high-quality material as the Move (Mock) base layer. The Move Hoodie features handwarmer pockets, a drawstring hood, and an embroidered Zerofit chest logo. It provides excellent fit and extra length in the body, ensuring coverage of the lower back for added warmth and protection against the cold.

Zerofit Leggings: Keeping the Lower Extremities Warm

Zerofit's Leggings offer the same level of thermal insulation as the Ultimate Move (Mock) turtleneck. These leggings are specifically designed to keep the lower extremities warm during cold-weather activities, such as motorcycle riding. With their comfortable fit and soft, stretchy flexibility, the leggings can be worn under insulated pants without hindering movement.

Durability and Care Instructions

Zerofit's base layer materials are constructed to withstand regular use. Despite deliberate attempts to stress the seams, no failures occurred, indicating their durability and quality. The base layers are also machine washable and can be tumble dried, providing convenience in terms of care and maintenance.
