Tank Size Guide

Every Bonk tank measures the same, OG Waffle and XSPORT alike. One chart, both builds.

Measurements

Garment measured flat, laid front-side up. These are the tank's dimensions, not body measurements.

Size Front length Chest, flat
XS 65 cm / 25.6 in 55.75 cm / 22.0 in
S 66 cm / 26.0 in 57 cm / 22.4 in
M 67 cm / 26.4 in 59.5 cm / 23.4 in
L 68.5 cm / 27.0 in 62.5 cm / 24.6 in
XL 69.5 cm / 27.4 in 65.5 cm / 25.8 in
2XL 71.5 cm / 28.1 in 68.5 cm / 27.0 in

Tolerance ±2 to 3.5 cm (±0.8 to 1.4 in). These are cut-and-sew garments, so expect small variation piece to piece.

How to read it

Front length runs from the highest point of the shoulder straight down to the hem.

Chest, flat is armpit to armpit across the front. Double it for the full circumference.

The cut

The tank is boxy and cropped. Across the run, the chest measures 86 to 96 percent of the length, so it sits wide and short rather than long and lean. That is the shape, not a mistake.

The surest way to size it: lay a tank you already like face up, measure it the same two ways, and match the numbers.

Rock Bonk.
