You can wear it roughly.
It's well made enough to wear as an inner layer or on its own!

It's loose, but the sleeve design is good.

This is my second purchase following the white one.
As per the reviews, once you encounter this long-sleeve T-shirt, opportunities to wear other plain long-sleeve T-shirts significantly decrease.
The width is roomy, and the length is not too long. The balance is just right.

This is a comfortably oversized white T! With subtle details, it's versatile for layering with a light outerwear or wearing it alone with accessories as it gets warmer.

I have repeated this so many times that I can't remember which set it is.
I wear it all day. It's perfect for layering, but also great on its own. It's comfortable, and I even use it as sleepwear.

I bought it for my son, but it felt a bit large.
I thought it could use a bit more of a fit.
I guess it depends on how you style it.

I also have the short-sleeve version in black and white, and this time I purchased the long-sleeve version.
I think I can now say that this is the only plain T-shirt I will need in the future.
The size is the same as the short-sleeve version, so it's fine.

I purchased a white long T-shirt. The oversized silhouette is moderately loose, and the dropped shoulder line and the width create a trendy relaxed feel. The fabric is neither too thick nor too thin, providing a good balance of breathability and durability. Even in white, there's no concern about transparency, so it's safe to wear on its own. The drape at the hem moves naturally, looking casual without being sloppy. There's minimal distortion after washing, making it very easy to use as daily wear. It’s also useful for layering regardless of the season, and I felt it offers great cost performance.

The neck area does not stretch easily, so it does not look sloppy, and I really like it.

The balance of body width and length is exquisite, making it incredibly easy to match and wear. I also plan to purchase different colors.

This is a replenishment. I'm sure there are many people like me who are getting more. About three years ago, I bought an XL, but this time I got an M. If you love tough t-shirts and oversized fits but haven't bought it yet, you should definitely try buying it once. It's a masterpiece.

The length of the hem and sleeves is a bit longer, and the drop shoulder fits nicely with the current oversized look. The cuffs are not ribbed but flat-sewn. The fabric is thick enough to be used as both an inner layer and a main piece. The color was more of a bluish white than a creamy shade.

The fabric is solid, and I'm liking it.

The fit is a bit large, so for my height, L feels a bit big, and M seems just right.

It's better not to think of it as a pack T. I bought it thinking it would be good as an inner layer, but it's too nice for that. It does show a bit of skin, so it's better to wear a tank top underneath, but it's a good long T that looks good on its own. If you buy one size up from your usual size, it should match your expectations.
I plan to share it with my wife, so I'm considering getting it in different colors as well.

It's loose, reversible but a bit difficult to wear.
I'm satisfied with the solid construction.

It's a generously large and easy-to-use size. You can feel the attention to detail, making it a great item whether worn alone or as an inner layer.

I was really happy with my short-sleeved purchase, so I also got the long sleeves.
I bought M for the short sleeve, but it was quite big, so this time I dropped a size.
The fabric is solid and loose, so I wear it as loungewear.
It seems a bit pricey at first glance, but since it comes in two pieces, and it doesn't lose its shape even after multiple washes, I think it's very cost-effective.

I have all the colors in short sleeves, so I wanted the long sleeves too!
These are just too cost-effective, I haven't worn anything else but the Cowlum pack T! Haha
It's not that I want to wear it oversized, so for 171cm and a normal build, size S fits just right!
It has a bit of width so it doesn't feel tight at all♪

The Cowlum's playful stitching and tags remain intact.
It's a pack T but the ounce is thick and feels good to wear.
I'm really finding it useful at this time of year!

I bought this along with the short-sleeved version. The review is almost the same as the other... The balance of the width and length is good, it's not too heavy or too light, and the crisp white with no yellow undertone is the best. It's so comfortable that I plan to buy different colors just like the short-sleeved version.

I like the snug binder neck and have been purchasing pack Ts for quite some time, but this is my first long sleeve. However, the snugness is looser than the pack T... There may be individual differences.

This year's model has slightly changed dimensions, and I struggled with the size, but S was perfect. For my body type, it feels somewhat loose overall, so if you want to wear it oversized, M might be better.
I hope they release individual sales and other colors!

Size → XL. I like the loose fit for myself! After the short sleeves in this series, I wanted the long sleeves... I thought they weren't in stock, but surprisingly they had them! I bought them immediately!
