Start with your waist and hip measurements, not your usual size

The Speed of Light Yoga Shorts come in five sizes from XS to XL, and the listing gives waist and hip measurements for each one. That is the most reliable starting point because the shorts are designed with a high waistband and a body-flattering fit, so the waist measurement matters more than it does on a low-rise short.

Measure your natural waist and your hips, then compare both numbers with the chart below. If you land between two sizes, the four-way stretch fabric gives you some flexibility, but the high waistband is the part that will feel tight or loose first. Choose the size that matches your waist most closely if you want the band to stay put during practice.

Speed of Light Yoga Shorts size chart

  • Speed of Light Yoga Shorts: Waist measurements: XS 26 3/4 in, S 28 1/4 in, M 29 7/8 in, L 33 1/8 in, XL 36 1/4 in. The high waistband sits at your natural waist, so this row decides whether the band feels secure or restrictive.

  • Speed of Light Yoga Shorts: Hip measurements: XS 37 in, S 38 5/8 in, M 40 1/4 in, L 43 1/4 in, XL 46 1/2 in. Hip measurement tells you how much room the shorts have through the seat, which affects comfort in forward folds and squats.

  • Speed of Light Yoga Shorts: Fabric: 82% polyester, 18% spandex, described as very soft four-way stretch. The spandex content explains the stretch, but it does not tell you to size down; use the measurements first.

How the high waistband and seams change the feel

Two construction details matter more than the size label: the high waistband and the flat seam with coverstitch. Here is what each means for fit.

  • High waistband: The band sits higher than a standard yoga short, so it covers more of your midsection. If you are long-waisted, check the waist measurement carefully; if you are short-waisted, the band may feel like it reaches your ribs.
  • Flat seam and coverstitch: These seams are designed to lie flat against the skin, which reduces bulk under leggings or during floor work. They do not change the size you need, but they do make the shorts more comfortable for intense sessions.
  • Body-flattering fit: The listing describes a body-flattering fit that stays comfortable during intense workouts. That is a design description, not a sizing instruction, so treat the measurements as your guide.

What the listing does not tell you about inseam length

The supplied product information does not include an inseam measurement. That is a real gap if you are choosing between short, mid-thigh and longer yoga shorts, because inseam length affects how much thigh coverage you get and whether the shorts ride up during certain poses.

Without an inseam figure, you cannot confirm from the listing alone whether these are very short shorts or a mid-thigh style. If inseam length is a deciding factor for you, ask the store before ordering or compare the product photos against a pair you already own. Do not assume a length based on the name or the model photos.

Are these the right shorts for hot yoga?

The Speed of Light Yoga Shorts are made from a soft four-way stretch fabric with a high waistband, and the listing says they are designed to feel comfortable during the most intense workouts. That combination suits hot yoga better than a loose cotton short, because the stretch fabric moves with you and the flat seams reduce friction.

What the listing does not confirm is moisture-wicking performance, quick-dry behavior, or breathability ratings. Those are common questions for hot yoga, but the supplied information does not include test results or fabric technology claims. If sweat management is your top priority, treat the polyester-spandex blend as a starting point and ask the store for any additional fabric details before you buy.

A practical fitting check before you commit

Once you have your measurements, use these checks to decide between two sizes or to confirm your usual size.

  • Waist band test: The high waistband should sit flat without digging in. If your waist is between two sizes, the smaller size will feel more secure but may compress; the larger size will feel softer but may slide during inversions.
  • Hip room test: Check the hip measurement against your fullest hip circumference. The four-way stretch gives some give, but you still want enough room to squat and fold without the fabric pulling tight across the seat.
  • Layering test: If you plan to wear these under leggings or loose shorts, the flat seam and coverstitch help reduce bulk. Size for the shorts themselves, not for the layer on top.

Care and material: what to plan for

The supplied information does not include care instructions for the Speed of Light Yoga Shorts. That means you should not assume a specific wash temperature, drying method, or ironing rule from this article. Check the care label on the shorts when they arrive, or ask the store for the manufacturer's care guidance before your first wash.

What you can plan for is the fabric composition: 82% polyester and 18% spandex. That blend is common in stretch activewear, but the listing does not state how it responds to heat, chlorine, or fabric softener. Follow the label rather than general advice.

Price and design context

  • Speed of Light Yoga Shorts: Designed by Asana Hawaii and priced at USD 28.14, with a catalog comparison price of USD 42.00. The price is part of the buying decision, but it does not change the sizing method: measure first, then compare value.
  • Speed of Light Yoga Shorts: Available sizes: XS, S, M, L, XL. The size range is limited to five options, so knowing your measurements helps you avoid ordering two sizes to try.
