I mean, summers in Oklahoma are no joke, heat, humidity, and requires for me to change my California wardrobe to something that breathes. I usually get XL for my size as I am not fit, but not super fat either, so helps to cover up and not be all tight fit.

I bought this as a gift. For reference, the person wearing this is 6' tall with a slim build and typically wears small or medium shirts, however, i had to size up with this shirt because everytime he raises his arms you can see up to his belly button. If you have a long torso and will wear this to the gym, I recommend a large. Otherwise a medium is good.

[ I appreciate the fine quality of the IB products and I specifically purchased this item for the next time I do overseas travelling because I like to have basic base layers. I now try to purchase mostly only 100% merino as this really makes a difference in the `` smell factor '', especially when you might be wearing the item for a couple days at a time. I like that these hand wash nicely in the sink and dry quickly. I purchase a large in t - shirts because my preference is a looser fit.

Tech t-shirts are designed to enhance performance during physical activities by providing moisture-wicking properties that keep you dry and comfortable. They often feature lightweight and breathable fabrics that allow for better airflow, reducing overheating. Additionally, many tech t-shirts offer stretch and flexibility, ensuring ease of movement whether you're running, training, or engaging in outdoor sports.
Tech t-shirts are typically made from synthetic materials such as polyester, nylon, or blends that enhance moisture management and durability. These fabrics are engineered to wick sweat away from the skin, promoting quick drying and comfort. Some tech t-shirts may also incorporate features like antimicrobial treatments to reduce odor, making them ideal for extended wear during workouts.
Tech t-shirts differ from regular cotton t-shirts primarily in their fabric composition and performance features. While cotton is breathable, it tends to absorb moisture, which can lead to discomfort during intense activities. In contrast, tech t-shirts are designed to wick moisture away, dry quickly, and provide a more comfortable fit during exercise, making them a better choice for active lifestyles.
Yes, tech t-shirts can be suitable for all seasons, depending on their design and layering options. In warmer months, they provide breathability and moisture management to keep you cool. In cooler weather, they can be layered under jackets or hoodies for added warmth while still offering moisture-wicking benefits. Choosing the right weight and style can enhance comfort throughout the year.
When selecting a tech t-shirt for workouts, consider factors such as fit, fabric type, and intended activity. A snug fit may be preferable for high-intensity activities, while a looser fit can provide comfort for casual wear. Look for features like moisture-wicking properties, breathability, and stretch to ensure the shirt meets your performance needs and enhances your overall workout experience.
