6.5 oz. Inner Shirt Long Sleeve 100% Cotton 4-Piece Set T-shirt Men's Crew Neck Soft Underwear Antibacterial and Odor-Resistant Undergarments Unisex All Season M Size No. 3531 Material Composition: 100% Cotton Care Instructions: Machine Washable Neck Style: Crew Neck Sleeve Type: Long Sleeve About This Product: "Important Point for Choosing a Size" If you prefer a looser fit, consider purchasing one size larger. "Triple-Stitched Natural Cotton Material" This long-sleeve T-shirt is made with a focus on quality, using 6.5 oz. of 100% natural cotton. It feels incredibly soft against the skin, absorbs sweat quickly, and dries fast, keeping you feeling fresh and comfortable. It stretches well and is treated with antibacterial and odor-resistant processing, making it safe for those with sensitive skin. What's amazing is the triple stitching! It's much more durable than the double stitching of regular T-shirts and won't lose its shape even after wearing it for a long time. "Hygienic! Individually Packaged 2-Piece/5-Piece Sets" It has three features: it doesn't fade, it's not see-through, and it's durable. It's comfortable to wear and won't wear out even with daily use, so you can enjoy it for a long time. Buying it in sets of 2 or 5 makes it easy to have replacements, and it's a great value! Each piece is individually packaged in a bag, protecting it from dust and moisture, and keeping it clean for storage, making it convenient to take on business trips or to the gym. It's great to buy a lot for yourself or to give as a gift, as it's always in a clean condition. "Unisex and Usable All Year Round" The neat stitching is less likely to unravel, and the tape from the collar to the shoulders and the triple stitching on the cuffs and hem prevent the shape from losing its form. It's a comfortable long-sleeve T-shirt that can be worn anytime, in spring, summer, autumn, and winter. It's unisex and has a silhouette that doesn't choose a body type, so it fits various body types and makes you look stylish just by wearing it. It's perfect for couples, families, and matching outfits for company or club events! "Usable in Various Situations" It can be perfectly matched with anything from casual wear to office casual. It goes great with any bottoms, from wide pants to skinny pants! It's useful in various situations such as going out, commuting, going to school, work, travel, shopping, and exercise. It's truly a high-quality, all-around long-sleeve T-shirt. Color: White系 (White-based) Pattern/Design: Solid
