Deciding between a boy shorts multipack and a trunks multipack for everyday wear? Compare fit, fabric, and coverage to find your ideal underwear.
Quick Answer
For most everyday wear, choose the Boy Shorts 3-Pack if you want a shorter, bikini-style leg line with ultra-soft TENCEL™ Modal fabric, or go with the 4.5" Trunks 3-Pack if you prefer a classic mid-length cut in a stretch cotton blend.
Coverage and Leg Length
Boy shorts have a 2.5-inch inseam and a mid-rise waist, offering a cheeky, sporty look that sits lower on the hip. Trunks have a 4.5-inch inseam, providing more thigh coverage and a longer silhouette that works well under shorts or looser pants.
Your choice depends on how much leg you want to show and how the underwear interacts with your outerwear. Boy shorts are ideal for low-rise jeans or skirts, while trunks are better for mid-rise pants and active wear.
Fabric Feel and Stretch
The Boy Shorts 3-Pack is made from TENCEL™ Modal, a buttery-soft, breathable, and featherlight fabric that feels like a second skin. It's highly stretchy to accommodate different body types and has flatlock seams to prevent chafing.
The 4.5" Trunks 3-Pack uses a supersoft cotton blend with a hint of stretch. It's more substantial and familiar, with a classic cotton feel that many people prefer for all-day wear. The stay-put waistband works well on both cuts, but the trunks' cotton blend may hold up better in high-heat conditions.
When to Consider Both
Some people keep both styles in rotation: boy shorts for lounging or wearing under dresses, trunks for daily errands or workouts. The multipack format makes it easy to stock up on your favorite cut without committing to a single style.
If you're new to gender-neutral underwear, starting with one multipack of each lets you compare fit and fabric firsthand.
How to Decide: Boy Shorts vs Trunks
- Choose Boy Shorts if: You want a shorter, sportier cut with a 2.5" inseam and a soft, lightweight modal fabric that feels like wearing nothing.
- Choose 4.5" Trunks if: You prefer a classic mid-length trunk with a 4.5" inseam and a cotton blend that offers a bit more structure and breathability.
- Try Both Multipacks if: You're unsure which cut you'll like best or want different options for different outfits. Multipacks give you three pairs per style at a better value than singles. Start with one multipack of each to compare fit and fabric firsthand.
