Gym Sweatshirts and Hoodies

Sweatshirts and hoodies are great for layering as you work up a sweat, whether it’s at the gym or running errands. Just be sure to drink plenty of water if you do sweat a lot.

What sets hoodies apart from traditional sweatshirts is that they have hoods. A hood can help to ward off chilly indoor air conditioning.


Sweatshirt fabrics can be soft, cozy and flexible. The ideal fabric for hoodies is cotton or polyester fleece. Neither fabric is particularly expensive, and sewing your own sweatshirt or hoodie can be quick and enjoyable! These fabrics also tend to be durable, making them long-lasting. You can even use a doubleknit rayon blend or silk jersey. Just make sure to follow the specific washing instructions to ensure proper care.

Historically, sweatshirts have been made from cotton fabric, which is comfortable and breathable. It is not as warm as fleece, but it still traps heat to keep you comfortable. Cotton is also biodegradable, which means that the fibers break down and return to the soil, unlike synthetics that can be harmful to the environment.

Many sweatshirts are now made from a cotton/polyester blend. This fabric is a bit warmer than cotton and more durable, and it can be treated to resist water or other liquids. It is a popular choice for workout hoodies because it helps absorb perspiration, which keeps the wearer dry and comfortable while they are active.

The Knickerbocker Manufacturing Company first introduced the modern sweatshirt in 1920, and it was designed to replace traditional wool football jerseys that caused chafing and itching. It features a loose fit and collarless design, and it may include a hood. Some hoodies are lined to add extra warmth, and the lining can be made from Sherpa fleece, flannel or synthetic insulation like 3M Thinsulate.


Fleece sweatshirts are a great choice for cold weather, as they offer warmth and comfort while being lightweight. They are also highly breathable, allowing heat to escape as it is produced, keeping the wearer comfortable. They can be worn alone or layered with other clothing, and are often designed with zippered pockets and adjustable features to maximize functionality and comfort.

Sweatshirt fleece fabrics are typically made from cotton or a combination of cotton and polyester, making them easy to wash and care for. They are also known for their durability, although this may vary depending on the fabric and design of the garment. Some fabrics may be more prone to pilling than others, but they can usually withstand regular wear and tear when properly cared for.

It is a good idea to keep a lint roller handy when working with sweatshirt fleece as it can shed a lot of lint when cut. It is also best to pre-wash the fabric before cutting out pattern pieces, as sweatshirt fleece can shrink considerably in the wash. It is also a good idea sweateshirthoodies to wash the finished garment separately from other items, as this can prevent colors and prints from bleeding.

Fleece hoodies can be customized with a logo, text or other images to create unique and personalized items. They can be printed using a variety of methods, including screen printing, embroidery and heat transfer.

Jersey Knits

Jersey knits are a popular textile that provides a soft, flexible, and comfortable fit. They can be made of natural fibers like wool or cotton or synthetics, but most are a blend of both. They also have a wide range of desirable qualities, including breathability, elasticity, and drape.

The fabric gets its name from the Channel Islands, where it was sweateshirthoodies first manufactured for practical sweaters and other warm winter clothing. Historically, it was made from a thick and heavy wool, but today it can be produced with a variety of materials. Some of the more common types include cotton, silk, and polyester.

While it is possible to hand-knit jersey fabrics, most are made using knitting machines. The process takes yarn and twists it together to create a close-knit pattern that looks like a latticework of twisted vertical threads connected by untwisted horizontal ones. The resulting fabric is durable and resistant to tearing, which is why it’s so widely used for sweaters and other forms of warm clothing.

One of the most common jersey fabrics is cotton, which is often paired with viscose or elastane (spandex) for added stretch and flexibility. When sewing with this type of fabric, it’s important to pre-wash it to prevent shrinkage and use a pattern that is specifically designed for knitted fabrics. It’s also a good idea to test a small piece of the fabric on an old garment to get a feel for how the seams will go together before proceeding with a full project.


Synthetic fabrics are petroleum products and have an outsized climate impact. But they’re still a popular choice for gym hoodies because of their moisture-wicking, breathability, and durability. They’re also often the most affordable option.

Nylon is a strong and lightweight synthetic fiber that’s often used for athletic wear, swimwear, and outerwear. It’s also resistant to wrinkles and fading, so it’s easy to care for. Polyester (also known as polyethylene terephthalate or PET) is a popular choice for shirts, lingerie, and yoga clothing because it’s stretchy and breathable. It’s made from oil and coal. It’s also anti-bacterial and quick drying.

Other synthetics include acetate, which is made from plant cellulose extracted through chemical processes. Rayon is another semi-synthetic fabric that looks and feels like silk but is actually a rayon/cellulose blend. This is a more eco-friendly and sustainable alternative to silk because it’s processed using fewer chemicals.

These synthetics are usually not as quick to dry as natural fibers, but they’re still great for activewear. Look for these fabrics to have a moisture-wicking treatment and polygiene odor control, too. They can also be combined with other materials, such as merino and nylon to create stretchy, comfortable, workout clothes that perform. When washing synthetics, always check the label for recommended temperatures and use a slower spin cycle to prevent them from getting damaged.
