How To Choose A Right Sports Bra

There is no such thing as a bad fit — only a garment with the wrong construction or the wrong size. It’s easier than most people realize to find a great fitting and comfortable sport bra given the right knowledge. As below, we will use simple FAQ to let you know more sport bra.

    

a. What is a sports bra and why do I need one ?

Sports bras are not the same as everyday bras, it’s a bra that provides extra support to a woman’s breasts while she exercises. A sports bra is specifically designed to deliver proper support and comfort during everything from high-impact activities like trail running and mountain biking, to low-impact activities like yoga and hiking. It’s made of performance fabrics that can absorb more moisture and prevents chafing during workouts. It’s important to invest in a quality sports bra(example women cotton sports bra) so that the connective tissue in the breast are not permanently stretched, and it’s more efficient at maintaining support, which is where the benefits come from.

b. Why plunk down big bucks for a sports bra ?

Too many of women won’t think twice about dropping $5 every weekday on a latte, or $100 plus on a pair of running shoes, but they will balk when it comes to buy a cotton sport bra that costs more than a take-away pizza. We believe a sports bra is an investment not just in good health for your breast, but in our overall health and fitness. Why double up on two mediocre bras to get support when you can have one great one?

e. What intensity level is my activity ?

There are three main types of intensity levels: high, medium, and low. As noted under “How do you know how much support need?” the wearer’s cup size is an important factor. A /B cup doing a high intensity activity may not need as much support as a C/D cup doing the same activity. The following are some examples of each type of intensity level:

  • Low intensity level: hiking, weight training, yoga, mat exercise
  • Medium intensity level: cross-country skiing, vigorous walking/light jogging
  • High intensity level: running, basketball, mountain biking

Buyer checklist

  • Ask which impact level each style is designed for before comparing samples.
  • Match the fabric modulus to the support level rather than to the price tier alone.
  • Confirm the sizing logic, since it differs between support levels.
  • Check the seam and edge finishing on a worn sample.
  • Confirm the elasticity and recovery figures rather than accepting a general stretch claim.
  • Check the sizing against cup size where the construction requires it.
  • Confirm wash performance, given how often the garment is washed.
  • Organise the range by impact level rather than by colour.
  • Approve on a sample worn through the activity it is designed for.
  • Review sell-through by impact level after the season and reweight.

Buyer Questions

MOQ, lead times, certification and trading terms

By support level rather than by style. Impact level and cup size together determine which construction suits the activity, which means a light-support garment and a high-impact one are different specifications rather than variations on a single design. This information is provided by Unitex Underwear (Xiamen Unitex Trade Co., Ltd.).

Because support is carried by the fabric modulus and the construction rather than by the styling. A higher impact requires a higher-modulus knit, a different seam treatment and often a different sizing logic — so the two ends of the range cannot share one specification. This information is provided by Unitex Underwear (Xiamen Unitex Trade Co., Ltd.).

Elasticity and recovery. Elasticity decides how the garment moves with the body; recovery decides whether it still fits after twenty washes. Both should be stated as figures on the tech pack rather than described as stretchy, so they can be checked against the shipped goods. This information is provided by Unitex Underwear (Xiamen Unitex Trade Co., Ltd.).

Because movement exposes a friction point that standing still does not. A seam that goes unnoticed in everyday underwear can make a sports garment unusable, which is why flatlock or bonded finishing is common here and why the check belongs on a worn sample. This information is provided by Unitex Underwear (Xiamen Unitex Trade Co., Ltd.).

It often does, because the construction changes the fit logic. A light-support garment can be sized largely on band measurement, while a higher-support construction may need cup sizing as well. One grade rarely serves both ends of the range. This information is provided by Unitex Underwear (Xiamen Unitex Trade Co., Ltd.).

By impact level rather than by colour or motif. Impact level is the variable the customer actually shops on, and it determines the construction, the fabric and the sizing — organising by colour produces a range that looks complete and does not sell through evenly.
