How to MeasureÂ
- CHEST: Measure around the fullest part of your chest, keeping the measuring tape horizontal.
- WAIST: Measure around the narrowest part (typically the small of your back and where your body bends side to side), keeping the tape horizontal. Be careful not to squeeze too tight to allow for extra room.
- IN-SEAM: Measure from the top of your inner leg along the inside seam to the bottom of your leg.
- Out-Seam: Measure from the top of your hip along the outside seam of your pants to your ankle.
Extra Tips
- Use a flexible measuring tape.
- For the best measurement, measure with your arms down by your side. Measure under your arms.
- If you are between two sizes, order the smaller size for a tighter fit or the larger size for a looser fit.

Technology
Technology in Athlos Men's Zero Vest
Made from Recycled Ocean WasteÂ
From the time we first explored Econyl in our running shorts, we've been gung-ho about its positive environmental impact. Built with recycled ocean waste, the Zero vest blends the right balance of performance and sustainability.
Fabric : The Big Mesh Up
We decided to design the vest with 75% mesh at the back. The mesh allows more room for air to circulate, keeping the stuffy heat and humidity from weighing you down.
With speeds over 100 kph Sailfish is the ocean's perfect athlete. Recycled from ocean waste, this fabric removes trash out of its way.
Details That Reflect Well On You
Spotting a runner at wee hours is easier said. And now done too! Our thoughtfully designed reflective details and graphics on the front and back ensure you are safely spotted even when the light isn't friendly.
Zero Vest Puts Humidity To Rest

In tropical humidity, most scratchy synthetic vest feel scratchier. Combined with the heat your long runs often end in discomfort. Breathable, swift-drying, and cooling against the skin, the Zero Vest ensures even your hottest long runs feel memorable.
