Best New Balance Mens Underwear Briefs in 2026

Prioritize Fabric Composition and Moisture Management

The most critical factor in selecting New Balance briefs is the material blend. For athletic use, you should look for synthetic blends—typically a mix of polyester, nylon, and elastane (Spandex). These fabrics are engineered for moisture-wicking, meaning they pull sweat away from your skin to the surface of the fabric where it can evaporate quickly. This is essential for preventing chafing and skin irritation during long runs or gym sessions. If you prefer a softer, more natural feel for lounging or casual days, look for blends that incorporate high-quality cotton with a touch of stretch. However, be aware that pure cotton lacks the rapid drying capabilities required for heavy perspiration.

Evaluate the Waistband Engineering

A common complaint with lower-quality briefs is the waistband rolling, slipping, or digging into the skin. New Balance tends to focus on wide, elasticated waistbands that sit flat against the hips. When shopping, look for a waistband that feels substantial but flexible. A high-quality elastic band should provide enough tension to keep the briefs in place during explosive movements (like sprinting or jumping) without leaving deep red marks on your skin. The seamless integration of the waistband into the body of the brief is also a sign of superior construction that prevents bulkiness under tight athletic leggings or joggers.

Understanding Support and the Pouch Design

The primary function of a brief is to provide containment and support. New Balance briefs often feature anatomical pouch designs that offer a contoured fit. This is a key decision factor: a well-constructed pouch provides lift and separation, which reduces friction between the thighs and the groin area. This 'anti-chafe' benefit is vital for preventing heat rashes. Pay attention to whether the briefs offer a more compressed, supportive feel (ideal for high-impact sports) or a more relaxed, ergonomic fit (better for recovery and casual wear). The amount of stretch in the pouch area will dictate how much freedom of movement you have during lateral shifts and deep squats.

Consider Seam Construction and Friction Points

To avoid the dreaded 'itch' during a workout, examine the seam placement. High-performance New Balance briefs often utilize flatlock stitching. Unlike traditional raised seams, flatlock stitching lies flat against the skin, significantly reducing the risk of chafing caused by the constant repetitive motion of walking or running. When evaluating a pair, check if the seams are placed away from high-friction zones. A brief with minimal, strategically placed seams will feel much more 'invisible' under your clothing and provide a more streamlined silhouette.

Sizing for Compression vs. Comfort

Because New Balance is an athletic brand, their sizing can sometimes lean toward a more 'performance fit.' If you are looking for maximum support to keep everything in place during a marathon, sticking to your true size is recommended. However, if you intend to use these briefs as your primary everyday underwear, you might consider sizing up slightly if you prefer a less restrictive, more breathable sensation. Always check the elasticity of the fabric in the product description. Higher elastane content means the briefs will conform more closely to your body shape without feeling overly tight.
