Responding to customer opinions and requestsRoomy design for comfortable wear
Relaxed fit for comfortLoose fit type
In response to feedback from customers who purchased the previous product (product number: YV2618P) that "it fits snugly and feels a little cramped" and "one size larger would have been fine," we have improved the width of the garment by making it approximately 5cm wider.
Sleeveless with sweat pad
YV2418/M・L・LL・3L
For first-timers, we recommend the standard type.
Minimalist cutting for a neat fitNormal sleeveless type
The cut is calculated so that the inner layer does not peek out from the neck or cuffs of the T-shirt. This is the classic type that is synonymous with in.T. If you are trying on in.T for the first time, this is the one to go for.

YV2618P/S・M・L・LL
Soft cotton feel that can be used all year round
Increased cotton content for a gentle feel against the skinSoft type with plenty of cotton
Cotton lovers will be happy to experience the comfort of a cotton feel. In addition, special processing has been used to reduce the disadvantages of cotton, such as its slow drying time and odor. This is also recommended for those who don't like the crisp feel of traditional cotton.
Cotton-rich sleeveless top with sweat pad
YV1578Q/S・M・L・LL
The long-awaited new color is here!!
The ultimate innerwear in pursuit of coolness!The fabric on the stomach area has been removed
Half-length type
The length has been cut in half, and fabric is effectively placed only in areas where sweating occurs. While maintaining the basic specifications of the in.T, this is the lightest T-shirt innerwear in the series' history.
Features

With sweat pads
Armpit sweat catcher
The armpits have large sweat pads that effectively absorb sweat and prevent sweat stains. Great for summer, or even under the heater in winter when you accidentally get sweaty.

In beige
Underwear is not visible
Available in multiple beige colors that blend well with the skin. The fabric is smooth and reduces nipple bulges. You won't even notice it's there, even if you wear it under a white T-shirt or dress shirt.

With a wide round neck
No glimpses
The neckline is wide and rounded, and the sleeves are shorter than those of T-shirts or polo shirts, so your underwear won't peek out from the collar or cuffs. It's a calculated compactness that doesn't interfere with the silhouette of your outerwear.

Because there are no seams
Hard to echo
The cut-off collar, sleeves, and hem have no seams. There is also no tag on the back of the neck, and the fabric is smooth, so you'll forget you're even wearing an undershirt.
