How to Stay Cool in Hot Weather – Know your Fabrics

Fiber Content

When finding the best lightweight travel clothing for hot climates, it’s essential to look at the fiber content to know what to expect. All fabric is not created equal; even if two garments look (and sometimes feel) the same on the outside, their fiber content (treatment or construction) may be entirely different, which means their performance will be different. Reading the content label and understanding fabric characteristics is the best way to choose appropriate clothing for hot climates.

What is a fiber content label? It is a label, required by law that discloses the generic names and percentages by weight of the constituent fibers in the product (along with a few other things) (source). The fiber label is usually sewn into the side seam or attached to the neck label of a garment. Checking the fiber content label is a great way to be an informed consumer and means you are one step closer to choosing the best lightweight travel clothing for hot climates!

Fabric Characteristics

In addition to fiber content, understanding fabric characteristics is beneficial when choosing the best lightweight travel clothing. Below are a few graphic tables listing some popular summer fabrics and their most attractive and least desirable features. It is a good idea to familiarize yourself with these fabric properties to help choose the best clothing for hot and humid climates.

You may notice absorbancy is considered an advantage and a drawback when choosing the best summer clothing for hot climates, but mainly for those planning to sweat during intense activities.

The main difference between water-absorbing (natural) and water-repelling (synthetic) fabrics is, absorbent fabrics, such as cotton, hold moisture next to your skin, making your garment wet and heavy. Excellent at cooling you down poor at keeping you comfortable. Water repellent materials such as polyester, pull moisture away from your body and trap the wetness between your skin and the garment. You will sweat more, but your shirt will stay dryer than cotton. Polyester won’t make you cold but may become clingy and smelly with excess moisture and of course, won’t breathe as well as natural fabrics.

Although basic poly and cotton have their problems, innovative high-tech polyester and performance cotton fabrics now have moisture control and wicking properties build right in. These fabrics pull sweat to the outside of the garment, allowing it to evaporate, keeping you cooler and dryer. These innovative fabrics are a great choice when choosing lightweight clothing for hot and humid climates, especially when working up a sweat.

Garment Fit, Construction, and Design

In addition to fiber content and fabric characteristics, garment fit, construction, and design are important variables to pay attention to while choosing the best lightweight attire for warmer climates.

  • Fit-if you are planning to be active moisture-wicking clothing is best. Make sure it fits tight or it won’t be able to do its job. If relaxing is more your speed, choose loose-fitting clothing.
  • Construction– Breathability increases with looser weaves and open knits; while tighter knits or weaves create less breathable fabrics. Finer yarns and lighter weight fabrics also affect breathability.
  • Design– Mesh cut-outs, zippered air vents, retractable collars, and sleeves are designed into garments to improve features such as UV ray protection and breathability.

Pro tip: D.I.Y garment breathability test; in a well-lit room, hold the garment up and see how much light passes through. More light=more breathability.

The Best Fabrics to Wear in Hot-Humid vs Hot-Dry Climates

Generally speaking, loose-fitting clothing and breathable fabrics such as cotton and linen are the best choices for staying cool in hot, humid weather. However, when choosing apparel to wear in warm weather, it is essential to select fabrics right for the type of activity you are doing and the type of heat you are experiencing. Humidity means more sweating, so depending on your activity, you may opt for tighter fitting, wicking clothing (summer wool or tech-polys) over naturally absorbent materials. In some cases, cotton is preferred for its natural cooling abilities, although it will become wet and heavy with excess moisture and eventually make you cold.

If you are an avid hiker, you probably have heard the popular rule of thumb “Cotton Kills.” Most hikers avoid cotton because of its absorbency, slow drying, and failure to regulate body temperature. In any case, always ask a professional if you are not sure what type of active clothing to choose for hot and humid climates.

Lightweight & Lose Fitting

Lightweight and loose-fitting are two sure things I look for when choosing warm weather clothing. Amazon is, of course, a convenient place to shop when looking for summer clothes. However, when it comes to quality fashion pieces on Amazon, those can be challenging to find. I’ve noticed A LOT of fast fashion brands selling on Amazon, which I try to avoid, but it can be hard to tell what is what. After a lot of trial and error, these are my favorite lightweight summer fashion finds perfect for warm-weather destinations. Most of them are still hanging in my closet, waiting for my next summer fun vacation!

Pro Tip: Lightweight dresses are great but if they are unlined (and sometimes even if they are) you might end up showing more than you bargained for. If a slip is out of the question, try the below comfortable stretchy sports shorts as an undergarment alternative.

UPF Protection + Performance

Hot temps usually mean intense sun which is best taken in moderation to prevent sunburn, wrinkles, and premature aging. Living in Florida, with fair complexion and freckles, I always do my best to protect my skin from too much sun exposure. Lightweight clothing with a UPF factor is a great way to enjoy the sun while blocking UV rays. Although all fabrics have a level of UV protection, not all fabrics are UPF protectant. Elements such as weave, stretch, wetness, color, and finishes all determine how well a garment will protect you from the sun.

Columbia’s PFG Tamiami and Bahama II shirts are my go-to sun-blocking and moisture-wicking shirts when spending the day outside in the hot sun. They come in so many colors, are lightweight, quick-drying, and easy to throw on when you start to feel the burn-plus they are wrinkle-resistant which makes them great for traveling!

I am also a fan of Patagonia’s tech-tee line Capilene® Cool. This is their “most versatile performance knit for use on trails or on the water.” This tech-tee provides 50+ UPF sun protection and HeiQ® Fresh durable odor control. Their styles range from tanks, short sleeve tees to long sleeve hoodies, and are available for men, women, and children.

For really active trips or long hiking days, summer wool is a must! Gone are the days of wool being a cold-weather garment only. With its moisture-wicking, breathing, and odor-fighting natural properties, merino wool has now evolved into a year-round staple. Wool also resists wrinkles so it is another great option for traveling.

Voormi and SmartWool both do a great job creating high-performance clothing, as seen in their line of Summer Weight Merino Wool Tees. Merino wool is more costly than its polyester competitor but well worth the money if you want something that works well and lasts. Shop some of their products below.

If you are looking for something a little more stylish Coolibar® is a great option. Their tech fabric innovations offer quick dry technologies along with soft, comfortable, lightweight, and breathable styles great for a hot and sunny day at the beach.

Bathing Suits and Cover-Ups

RipSkirt Hawaii is a brand I discovered after reading an article about women entrepreneurs. This water repellent skirt allows you to cover up easily and quickly after a day on the water without the dreaded wet butt stains. They come in three lengths and a variety of colors. I just ordered my first one and can’t wait to try it!

Ondademar, a Columbia Swimwear brand, is one of my favorites. I love their prints and luxurious feel of their Nylon+Spandex suits. You can sometimes find older styles discounted on Amazon in limited sizes. Trina Turk is another swimwear brand I can’t get enough of. With so many prints, colors, and styles, I often wear their suits paired with shorts or a skirt around town, not just to the pool or the beach.

Long sleeve suits are quickly becoming my new favorite thing. For one, it’s the best way to avoid using sunscreen! Rip Curl and Billabong introduce a few new styles every season and are my favorite sporty swim brands. Some of the cheaper Amazon brands don’t hold up as well but are great for casual wear during low-impact activities.

Pro Tip: Long sleeve bathing suits are great for wearing under a wet suit when scuba diving. They help the wetsuit glide on and off your body without riding up like a rash guard.
