Phase Shorts Sizing: How to Pick Your Size Before Buying

Use these Phase Shorts sizing decision rules to choose the right size the first time, understand how the fit should feel, and know when to size up or down.

Quick answer

Start with the size you normally wear in SAXX bottoms, then use the waistband and seat as your checkpoints: the Phase Pant should sit flat without digging in, and the midweight fabric should drape rather than pull across the hips. Size up only if you are between sizes or want a looser, recovery-day fit.

Why the fabric changes the sizing decision

The Phase Pant is cut from a butter-soft midweight fabric with 4-way stretch, so it moves with you instead of holding a rigid shape. That stretch is helpful, but it can also mask a waistband that is slightly too tight until you have worn the shorts for a full day.

Because the fabric is wrinkle-resistant and quick-drying, these shorts are likely to travel with you and get repeated wear. A pair that only feels acceptable in the fitting room is more likely to become uncomfortable on a long flight or a full day of walking.

The waistband is the first checkpoint, not the only one

A common mistake is judging Phase Shorts only by whether the waist closes. The waistband should sit flat against your body without rolling or leaving deep marks. If you can fit more than a finger or two comfortably inside the waistband while standing, the shorts may be too loose and will slide down once the fabric relaxes.

Check the seat and thigh next. The shorts should allow you to squat and sit without the fabric pulling tight across the hips. If the seat feels restrictive before you have moved around, that is a sign to try the next size up rather than relying on stretch.

When to size up and when to stay put

Size up if you are between sizes, prefer a relaxed fit for recovery days, or plan to wear the shorts over heavier underwear. The midweight fabric has enough structure that a slightly larger size will still look clean rather than baggy.

Stay with your usual size if the waistband sits flat, the seat feels comfortable when you sit, and the leg opening does not gape. Do not size down hoping the shorts will feel more supportive; the 4-way stretch already provides movement, and a tighter waistband will not improve the fit.

Phase Shorts sizing decision rules

  • Start with your usual SAXX size: Order the size you normally wear in SAXX bottoms. The Phase Pant is designed as an everyday silhouette, so there is no need to automatically size up or down unless you are between sizes.
  • Size up if you are between sizes: If your measurements fall between two sizes, choose the larger one. A slightly roomier waistband will sit flat and leave room for the fabric to drape, while a too-small waistband will dig in during long wear. Check the waistband while seated, not just standing.
  • Stay with your size if the waistband sits flat: If the waistband lies flat without rolling and you can sit and squat without the seat pulling, keep your usual size. Do not size down for a tighter feel; the 4-way stretch already provides support.
  • Choose a looser fit for recovery days: If you want the shorts mainly for lounging or travel recovery, a size up gives a more relaxed drape without looking sloppy, thanks to the clean silhouette and wrinkle-resistant fabric.

Phase Pant at a glance

  • Phase: Midweight fabric with 4-way stretch, quick-dry ease, and wrinkle-resistant wear. The stretch helps the shorts move with you, but the midweight hand means the waistband and seat should still fit correctly from the start rather than relying on give.
