Top Tips for Choosing the Right Men’s Underwear
Finding the perfect pair isn’t just about size—it’s about comfort, purpose, and personal style. Here are a few handy tips to help you pick the right underwear for your day:
1. Match Your Layers to the Weather
Heading out into the cold? Thermal underwear is your best friend. A long-sleeve thermal vest and long johns make a solid base layer for staying warm without bulk.
2. Cotton is King for Everyday Comfort
For daily wear, breathable cotton boxers are a solid choice. Look for soft jersey fabrics that move with you and keep you cool.
3. Think About Fit
Boxers, briefs, or something in between—your perfect style depends on your fit preference. Boxers offer a relaxed feel, while fitted styles provide more support.
4. Stock Up, Stress Less
Having a few extra pairs on hand means no last-minute scrambles on laundry day. Multipacks are a great way to keep your drawer fully stocked.
5. Style Meets Function
Bold prints or classic colours—there’s no rule that says underwear can’t be fun. Choose a design that fits your personality (even if no one else sees it).
Whether you're stocking up on everyday essentials or preparing for the colder months, Charlies’ selection of men’s underwear has everything you need to stay comfortable, whatever the day holds.
