Questions About Underwear

What underwear brands does Northern Threads stock? +

We carry a strong range of premium men's underwear from Calvin Klein, Tommy Hilfiger, and Emporio Armani EA7. These brands are known for quality cotton and modal fabrics, excellent waistband construction, and iconic branding that has made designer underwear a wardrobe staple.

How do I find the right underwear size? +

Designer underwear is sized S/M/L/XL based on waist measurement in inches. Generally: S = 28-30 inches, M = 32-34 inches, L = 36-38 inches, XL = 40-42 inches. Always check the brand's specific size chart as Calvin Klein and Tommy Hilfiger can vary slightly.

What is the difference between cotton and modal underwear? +

Cotton underwear is breathable, durable, and excellent for everyday wear. Modal is softer and more fluid with a silkier feel against the skin, and is popular for its comfort. Calvin Klein's Modern Cotton range blends both for a soft, breathable everyday option.
