Fleece Wear Guide

Montbell fleeces are made using a wide variety of fabrics, offering a rich selection for any season and activity.

LINE UP

Our lightest, thinnest fleece fabric Chameece is knitted using very thin (less than 1 denier) micro polyester yarns. Like its namesake, the soft leather from the Chamois Antelope, Chameece has a luxurious hand. We produce this sinful softness with a high fiber count, tight weave, and brushed face. Weighing only 160 grams per square meter, this micro-fleece is light, compressible, and quick to dry.

TRAIL ACTION


With excellent stretch, low volume loft, and a smooth face for better layering and increased durability, these garments are designed for an active lifestyle.

This fabric is specially knitted to provide a “sweater-like” exterior, while maintaining the warmth and versatility of our traditional mid-weight fleece. Weighing in at 255 grams per square meter this fabric helps us balance function and style. Clothing made with ClimaPlus Knit function well as an inner insulating layer during the day on the mountain, but never look out of place when relaxing at the lodge late into the evening.

The thinnest of our traditional fleece, ClimaPlus 100 weighs in at 220 grams per square meter and easily satisfies the role of inner layering piece or lightweight outerwear without blowing the budget.

Being a blended fabric, CLIMAPLUS™ WOOL capitalizes on the inherent strengths of both wool and polyester. The result is a soft, quick to dry fabric that is quite warm for the weight.

Our long fiber fleece is very breathable, dries quickly, and offers “high pack-ability” despite its impressive loft. The soft, fur-like fibers trap copious amounts of air to yield incredible warmth at a minimal weight. Garments made with ClimaAir fabric maintain their insulating ability by resisting pilling after multiple washings.

Information

Chameece and ClimaPlus 100 products feature our patented Slan-Tec Cuffs. By orienting the seams of the cuff at an angle the sleeve can easily be pushed up the forearm with minimal binding and increased comfort. In addition, all of our fleece garments feature zipper “pockets” to shield the users skin from the metal zipper slider. These soft fleece pockets protect the users sensitive neck and chin from cold metal in freezing temperatures. Finally, at Montbell, we incorporate articulated patterns and control fiber thickness in all of our fleece clothing to promote greater freedom of movement, comfort, maximal insulation.

The secret to breathable warmth

The most important properties when in search of a garment for a middle layer are breathability and insulating ability. In many ways fleece clothing can strike the perfect balance of the two.

The chief ingredients in fleece are polyester and polyethylene terephthalate (or PET) which are hydrophobic. Fabrics made with fibers like these “hold less water” have the ability to hold more warmth, while drying more quickly. Also, by selecting ultra-fine filaments and brushing the finished material we can create many small spaces between individual fibers in the fleece. These gaps and spaces trap air, not allowing it to move freely, thus creating a high level of insulation. This trapped air is sometimes referred to as “dead air” and is exhibited in natural insulators like wool and down.

When compared with wool and down garments, fleece items can be superior because we can more closely control fiber length and diameter, along with fabric thickness and density to better tailor apparel performance to address seasonal weather conditions and activity level.
The open nature of the knit utilized in fleece can promote better garment breathability. By allowing air to easily pass thru the fabric fleece clothing can feel less “stuffy”, combating perspiration to keep you drier at a variety of exertion levels. The short dry time of fleece also keeps you safer and more comfortable than other insulators.
When paired with wind proof membranes or linings the thickest fleece can be highly efficient and can rival thinner low grade down garments in warmth.

Compared with down or wool garments, one of the advantages of fleece is the variation available in its hair length, fiber diameter and cloth thickness, which allow us to make suitable fleece garments for any weather condition no matter if it is summer or winter.

Fleece’s breathability helps keep you dry and it also releases just the right amount of built up heat during strenuous activities, such as when breaking trail in waist deep snow. Normally the inside of your clothing would feel “stuff” because the temperature difference inside your clothing is so much higher than your outside environment, but fleece allows this excess heat to pass through the fabric easily.

It is often compared to down for its insulating properties, but thicker varieties of fleece with a windproof lining can prevent heat from escaping between the fibers, allowing it to easily hold its own against such products.
