Bontrager B1 Sleeveless Baselayer

Bontrager garment fit is based on an athletic build, and follows true sizing. Reference the clothing size chart to identify your size, then see the item's fit profile to understand how the silhouette will move with your body.

Men's clothing

Measurements on the sizing chart reflect the actual measurements of the body’s circumference (not product’s measurements). Use a cloth measuring tape to measure your body. All measurements should be taken while standing up straight with feet shoulder width apart. For maximum accuracy, take measurements next to skin.

1CHEST
Measure around the fullest part of your chest under your armpits with your arms relaxed at sides. Keep the measuring tape parallel to the ground.
2WAIST
Measure around the natural waist, which falls at the natural curve of the body—the indentation between the hips and the rib cage. The measuring tape should be close to the body but not snug.
3HIPS
Wrap the measuring tape around the fullest part of the hips and buttocks. Keep the measuring tape parallel to the ground.
