Buy the Men's Comox Trunks sewing pattern from Thread Theory. These form-fitting trunks are designed with comfort in mind. No centre back seam, a reinforced inseam gusset and a shaped front cup make these boxers fit like a second skin without the worry of rubbing or shifting. Short athletic legs and a smooth elastic waistband create a streamlined silhouette that can be worn under everything from slim fit pants to gym shorts.

Suggested fabrics: Cotton, bamboo, or blended lightweight knit with (preferably) at least 4% spandex/elastane and four-way stretch. The knit you choose should have 60 - 70% stretch. For sporty, versatile trunks, choose a lighter weight knit. For thicker, cosier trunks, choose a heavier t-shirt weight knit. Avoid tissue weight knits as these will not be strong enough.
