Product Description
Yamatomichi Chemical B French Sleeve (Women's)
■Excerpt from the manufacturer's description
The Chemical B series from Yama to Michi comes in Wide Fit, Standard Fit, and Slim Fit; the Chemical B French Sleeve is a Standard Fit.
*Precautions for Use*
■Differences in Characteristics Based on Color
・Due to differences in dye concentration, there are variations in the functional properties achieved through processing; while the fabric strength of Off White is slightly lower than that of other colors, its antimicrobial performance tends to be relatively higher.
・Due to the fabric's unique mottled texture, the same color may appear to have slight variations in shade.
■ About Odor Absorption
There have been reports of people noticing odors, such as body odor, when wearing items previously worn by others. It is possible that the body odor of someone else—to which the wearer is not accustomed—became absorbed into the fabric, causing a particularly noticeable sensation of discomfort. There have also been reports of people noticing the smell of algae after wading in rivers or streams.
In the following situations, Chemical B may not be able to fully demonstrate its antibacterial, deodorizing, and odor-eliminating properties.
・When sebum builds up excessively
・When the pH of sweat is high after sweating
・If alkaline detergents or chemicals remain on the surface
・When acidic odor-causing compounds (e.g., butyric acid, isovaleric acid, etc.—so-called body odor derived from skin flora) increase due to factors such as leaving wet clothes unattended
■Regarding Stitch Marks at Seam Lines
Due to the nature of the fabric, stitch marks tend to remain after sewing, and small holes from the stitches may become visible if you pull on the sewn areas. While this does not affect normal use or wear, please avoid pulling on the fabric too hard.
■Stays Warm, Odor-Free, Standard Fit
The "Chemical B" base layer series, developed in collaboration with Teijin Frontier, eliminates the problems of "chills from sweat" and "odor"—which have traditionally been the weaknesses of synthetic fiber base layers.
It quickly wicks away sweat and dries, and its fabric structure—which makes point-to-point contact with the skin—helps prevent chills caused by sweat. Furthermore, the mildly acidic yarn inhibits bacterial growth, preventing unpleasant odors. It is truly the perfect base layer that combines the best features of synthetic fibers and merino wool.
In particular, the Chemical B French Sleeves—featuring a pattern designed to naturally conform to a woman’s body—are the perfect base layer for active mountain adventures, and we especially recommend them to those who have traditionally avoided synthetic fabrics.
・Excellent at wicking away sweat, keeping you comfortable even during prolonged, high-intensity activities
・Although it is a synthetic fiber, it offers excellent odor-preventing and deodorizing properties, and the effects last a long time.
・Lighter than merino wool
・Although made of a lightweight mesh fabric, it is durable and resistant to pilling
■Details of Each Part
・The neckline is double-stitched using the same fabric as the body, creating a clean, streamlined look. The sleeves are short French sleeves.
・The neck area is reinforced with tape running from both shoulders to the back of the neck.
