When choosing clothing for chilly seasons, you may sometimes wonder whether to choose fleece or an insulated jacket.
Both are used to provide extra warmth, but they differ in material construction, feel, and their ideal applications. It becomes easier to choose once you consider whether you want to "wear it while walking," "throw it on during breaks," or "use it for daily wear."
What is fleece?
Fleece is clothing made from brushed fabric. It often has a soft texture and is used both as a standalone piece and as a mid-layer worn under a jacket.
It comes in various types, ranging from thin and lightweight to thick and heavy. The warmth, breathability, and bulk vary depending on the thickness and the way the fabric is knitted.
The name "fleece" alone does not guarantee wind resistance or water resistance. In places exposed to wind, consider wearing a shell layer over it as needed.
When to choose fleece
・Strolling around town on a chilly day
・As a mid-layer while hiking
・When you prioritize a soft, comfortable feel
・When you want to add warmth under a shell
What is an insulated jacket?
An insulated jacket is a garment with insulating material (fill) between the outer shell and the lining. In this article, we mainly refer to jackets that use synthetic fiber insulation.
There are various types of insulation, and PrimaLoft® is one such option. However, even with materials that carry the PrimaLoft® name, the construction differs between insulation-type and fleece-type versions. In addition to the material name, check the actual construction of the product.
The warmth and feel of an insulated jacket depend on the type and amount of insulation, the outer fabric, the lining, and the silhouette. The usage also differs between models designed for thin layering and models designed to be worn as an outer layer.
When to choose an insulated jacket
・When you want to throw on an insulating layer while out on a chilly day
・When you want to add warmth during a break
・When you want to use it as an outer layer for commuting or walking around town
・When you are looking for an insulating layer to carry with you
Differences between fleece and insulated jackets
| Key points for selection | Fleece | Insulated jacket |
|---|---|---|
| Structure | Uses brushed fabric | Includes insulation for warmth |
| Feel | Often soft | Varies by outer fabric, insulation, and structure |
| Layering | Many models are easy to use as a mid-layer | Includes both mid-layer and outer-layer types |
| Wind resistance | Check for windproof features | Check the specifications of the fabric and seam construction |
| Warmth | Varies by fabric thickness and structure | Varies by insulation type, amount, and structure |
This is just a guideline for selection. An insulated jacket is not necessarily always warmer than fleece. It is important to compare individual products.
If wearing while active
While walking, you may get hot depending on your level of exertion. Check not only for warmth but also for breathability, ease of movement, and how easily it can be adjusted.
If you choose fleece, the key points are the thickness of the fabric and how it feels when a shell is worn over it.
If you use an insulated jacket while active, check its thickness, breathability, and the construction around the underarms and back. It is convenient to choose a model that is easy to unzip or take off to avoid getting unnecessarily hot.
If throwing on during breaks
Even if you are comfortable while walking, you may feel cold when you stop. When choosing an insulating layer for breaks, in addition to warmth, check whether it can be worn over the clothes you are currently wearing.
If you are carrying it, weight and packed size are also selection factors. If the product has a storage bag or packable feature, check how to use it.
Whether you choose fleece or an insulated jacket, it is important to prepare according to the weather at your destination and the duration of your activity.
If using for daily life
If you also wear it for commuting or walking around town, check how well it goes with your usual clothes, as well as the pockets, length, and ease of putting on/taking off.
Fleece is a choice that is easy to incorporate on days when you are moving between indoor and outdoor environments. You can also wear an outer jacket over it to match the cold or wind.
Some insulated jackets can also be used as everyday outerwear. Choose by considering the ease of movement when combined with the clothes you wear underneath, and whether it will make you too hot in the places you will be wearing it.
Considering a vest
If you find that layering long-sleeved garments makes your arms feel restricted, a vest can be an alternative.
Fleece vests or insulated vests can add warmth to your core while reducing bulk around the arms. In addition to wearing them over shirts or long-sleeved T-shirts, they can also be layered under a jacket.
However, since the arms are not covered, they do not provide the same range of insulation as garments with sleeves. Combine them according to the temperature and the situation.
Check the size together with the clothes you will layer
If using it as a mid-layer, check that you can move your shoulders and arms easily even when wearing a shell over it. If you are wearing it as an outer layer, you need extra room for the clothes worn underneath.
When trying it on, raising your arms or stretching them forward in your actual outfit will make it easier to confirm the fit.
・Do the shoulders and back feel tight?
・Do the underarms and arm areas feel restricted?
・Does the hem ride up significantly?
・Is the zipper easy to operate?
・Are the cuffs and hem suitable for how you intend to use it?
For care, check the garment care label
For both fleece and insulated jackets, the appropriate care methods differ depending on the material and structure.
Follow the product's care labels and instructions for washing, drying, and the use of fabric softeners. Even products with the same material name cannot always be cared for using the same method.
Choose by matching warmth with intended use
When choosing between fleece and an insulated jacket, be sure to check not only the warmth but also the situation in which you will wear it, breathability, ease of layering, and portability.
The role required for a piece worn while active may differ from one thrown on during a break. It is important to think about how you plan to use it and check the specifications of each product.
The PrimaLoft® collection at Monterest offers items using both fleece and insulation. Please take a look and find a piece that suits your layering needs while checking the differences in material and construction.
