Size chart packs

This chart applies to Ultimate Direction running vests and vest-style packs. Aarn packs are one-size with an adjustable harness, so no chart needed; see the fit notes on the product page, or come in and we'll fit it with weight in it.

Running vests are sized by chest circumference so the load sits tight and bounce-free. Measure your chest, match the band below, then confirm against the size tab on the specific product; models vary and the women-specific Vesta runs a touch narrower.

How to measure your chest

  1. Wrap a soft tape around the fullest part of your chest, under the arms and across the shoulder blades.
  2. Keep it level and snug, not tight. Breathe normally.
  3. Match to the band below. On a boundary, the adjustable sternum straps mean either works: size down for a racier fit, up for layering.

Ultimate Direction vest sizing

Size Chest (cm) Chest (in)
XS 73-84 29-33
S 80-92 31-36
M 84-100 33-39
L 94-114 37-45
XL 100-127 39-50

Women-specific Vesta models run slightly narrower (XS from ~70 cm chest). Some packs (e.g. Fastpack) use S/M and M/L bands rather than single sizes; check the product size tab. Source: Ultimate Direction vest size chart.
