Learn how to size the BOA Men's 3.75" Slasher V-Notch shorts in Navy Blue. Follow our step-by-step fit check and avoid common sizing mistakes.

Quick answer

Choose your usual BOA size for the Men's 3.75" Slasher V-Notch in Navy Blue. The 3.75-inch inseam and V-notch design provide a versatile fit for both running and casual wear.

Why the V-notch changes the fit conversation

A V-notch short is not the same as a split short. The notch is a small cutout at the side seam that adds a bit of extra room for your stride, but it doesn't open all the way up like a race-day split short. That means the Slasher V-Notch gives you freedom of movement without the full exposure of a split short. If you're used to split shorts, expect a more modest cut; if you're used to standard running shorts, expect better mobility.

What the 3.75-inch inseam means for you

At 3.75 inches, this short sits in the middle ground: shorter than a 5-inch trainer but longer than a 1-inch elite split. It's a length that works for most runs and won't look out of place at the gym or coffee shop. If you have particularly long legs or prefer more coverage, you might find it on the short side; if you're coming from 1-inch shorts, it will feel like a relaxed option.

How to size the Slasher V-Notch in Navy Blue

Measure your waist: Use a soft measuring tape around your natural waist, keeping it snug but not tight. Compare to the BOA size chart to find your baseline size. If you're between sizes, consider sizing up for a more relaxed fit, especially if you plan to wear the shorts for both running and casual use.
Check the liner: The built-in ventilated copper-infused anti-microbial liner is designed to fit close to the body. Make sure your measurement allows for a comfortable liner fit without restriction. If you prefer a looser liner fit, sizing up may help, but be aware the outer short will also be roomier.
Consider your activities: For running, a snugger fit reduces bounce; for gym or casual wear, a slightly looser fit may be more comfortable. Decide how you'll use the shorts most often. If you're primarily running, stick with your measured size; if you're mixing activities, consider sizing up for versatility.
Try them on and move: Once you receive the shorts, try them on and do a few squats, lunges, and a short jog. Check that the V-notch allows unrestricted movement and the waistband stays in place. If the waistband digs in or the liner feels tight, exchange for a different size before washing.
