Hiking is an excellent way to get fit and reconnect with nature. For many hiking enthusiasts, fall is the best time of the year to venture out into the wilderness, thanks to the cooling temperatures. However, finding the best T-shirt materials for fall hiking isn’t so simple. Here are three fabrics that are preferred for fall-time outdoor activities.

If you’re a serious hiking enthusiast, there’s no better T-shirt material than merino wool. The fabric features exceptional breathability and comfort, making it the ideal base or mid-layer for outdoor physical activity. It’s also very lightweight, meaning it’ll fit perfectly underneath your other clothing garments.

Merino wool is the most moisture-wicking type of wool! But what really sets merino wool apart from the other T-shirt materials on this list are its natural antimicrobial characteristics, which prevent the accumulation of bad odors. Unfortunately, this fabric is significantly more expensive compared to synthetic alternatives.

A blended material typically means a mixture of spandex and nylon, and it’s a very popular choice for hiking T-shirts. It’s quite flexible and designed to move with your body. Plus, it’s softer and thinner than cotton or other popular fabrics. Regarding moisture prevention, nylon and spandex are excellent at absorbing sweat and water. Shirts with higher blends are considered better quality, but they will cost you more money. Unfortunately, blend materials are poor at preventing bad odors.

Polyester is undoubtedly the fabric of choice amongst most hikers, regardless of experience. Synthetic materials are often quite affordable, and there’s always a ripe supply of polyester shirts in stores and online. These lab-produced fabrics are specifically designed to combat moisture and dry quickly, preventing you from being a sweaty mess following your hike. Like blended material, polyester retains unpleasant smells longer than more expensive options. Ultimately, many people choose polyester as it naturally blocks harmful UV rays.

These three fabrics might be the best T-shirt material for fall hiking, but which option is most suitable for you and your needs? If you hike often and are willing to invest more money into your hobby, consider purchasing merino wool. Otherwise, blend material and other synthetic fabrics like polyester work perfectly fine. Pair your T-shirt of choice with a quality mid-layer garment to create the ultimate fall hiking outfit!
