When it comes to everyday wear, the material, including moisture-wicking materials, will play a crucial role in buying kids' underwear. Little kids want to play all day long in their underwear, which means the choice of fabric will make a big difference.

  • Comfort: The fabric should be able to give your kids the freedom they want. The best material for kids' underwear should hence be super soft on the kids' skin, so they can be themselves.

  • Breathability: Choosing a fabric that enables good ventilation for your kids’ skin is important. Cotton is the best option in this regard to help air flow efficiently throughout the day.

  • Moisture-wicking: Pick a fabric that doesn't irritate skin due to moisture and sweat. Therefore, cotton is the most sensible option for everyday wear, as it shouldn't make kids feel wet or irritated.

  • Skin health: Pick a type of fabric that will not cause chafing, itching or even cause rashes. The safest material will keep your child’s skin safe from all of these irritations.

  • Durability: When it comes to clothes, there are a lot of wash cycles, especially in the case of underwear, so the material needs to remain intact.

  • Affordability: Along with being breathable and having great quality, parents want an affordable choice which would not be heavy on their pockets when their kids outgrow their clothes.

Plan B makes innerwear that is super soft on the skin, with breathable fabrics, which is great for sensitivity and perfect for daily wear across their girls' underwear, boys' trunks and boys' briefs, while also providing more support.

No matter which material you purchase, cotton is always the winner. Both parents and kids choose breathable fabric.

Cotton clothing is at the top of all the lists of best fabrics since, as compared to the majority of other fabrics, cotton is warm, gentle against the skin, and does not produce heat inside the clothing.

  • Breathability: Plan B offers innerwear made from cotton fabric, which is airy and allows for the kids’ skin to breathe. It is ideal for your kid's most vigorous pursuits, soaking up sweat and moisture. The breathability of the material allows the sweat to be soaked up regardless of how much your kid plays.

  • Hypoallergenic: Unlike other materials, cotton is skin-friendly. It minimises rashes and skin irritation, which is a characteristic every parent would appreciate. So even children with sensitive skin can wear them worry-free.

  • Softness: Natural fibres like cotton fabric are soft, warm and perfect for being worn for longer periods of time. So that when your kid wears Plan B innerwear all day, it will feel gentle and soft on their skin.

  • Durability: Cotton can shrink at times, but it holds up even after regular washing. Plan B innerwear will maintain its shape and fit even after washing it many times.

  • Moisture absorption: Cotton makes all the difference as it has moisture-wicking ability, but it might feel damp when the climate is super hot. During summer, Plan B’s super soft innerwear makes sure that your kids don’t feel anything moist

  • Affordability: The best underwear fabric is one which is readily available and super cost-effective, and Plan B’s innerwear collection has both these aspects.
    Using premium cotton fabric, Plan B's boys' underwear and girls' trunks are perfect for all-day wear as they balance both softness and comfort equally.

Other Materials to Consider for Underwear: An Overview

Cotton is the winner, but other fabrics like modal underwear, nylon, polyester blends, temperature-regulating fabric and bamboo will all bring their own advantages and disadvantages. You would want to mix and match as per your kids' choices and body types.

Modal – Softness and Moisture-Wicking with Modern Performance

  • Soft and breathable: This fabric type feels soft and cool against the skin.

  • Moisture-wicking: This aspect would enable the fabric to stay dry for a long time.

  • Durability: The fabric is also durable enough that it won't shrink or fade.

  • Affordability: It has a premium feel, but it is priced highly in comparison with cotton.

Nylon – Durability and Stretch for Active Comfort

  • Elastic and durable: Even when wearing for sports and activities, it is a great option.

  • Quick-drying: This is the best option for the monsoon and also for kids who are super active.

  • Less Breathable: This fabric, however, may trap heat inside the synthetic materials because it is not made of cotton.

Polyester – Quick-Drying and Lightweight for Active Days

  • Lightweight and durable: Even when worn in an intense active lifestyle, this fabric is durable enough to withstand all the wear and tear.

  • Quick-drying: In hot and humid climates, when kids tend to sweat the most, polyester blends are perfect.

  • Less breathable: This fabric is, however, not as breathable as cotton is.

Bamboo – Eco-Friendly and Naturally Antibacterial

  • Soft and sustainable: Bamboo has a luxurious feel and is the smoothest fabric.

  • Moisture-wicking and antibacterial: This fabric reduces the odour that is usually trapped inside the clothes and any bacteria build-up.
