Runderwear Easy-On Running Bra: first impressions

The Runderwear Easy-On Running Bra is a wonderfully supportive, simple sports bra for running with wide straps and padding up front for extra support.

It has a non-optional racerback design that makes it a little unique, and means you have to put it on in a different way to many other bras we’ve tested. Unlike with the Panache, Pure Lime and Shock Absorber bras, for example, you absolutely cannot do up the three-hook racerback by reaching back between your shoulder blades; you must do the three-hook chest band and three-hook racerback straps up together at the front, turn the whole bra around and then scoop your arms through the shoulder holes. Once you’ve got the hang of this, and don’t keep forgetting to connect the racerback bit, it can be truly described as Easy-On (see also: a guide to different types of sports bras).

The padding is a little more than the other bras we tested in this category, but the fabric is comfortable, moisture-wicking and chafe-free so it works in a wide range of temperatures. The price is very high, but it’s great that these bras go all the way to a 42E or 40H – fantastic for the well-endowed.

• Size range: 30-42, C-H
• Weight (34D): 119g / 4.2oz
• Colors: Black / Black & Blue / Blue / Pink

• Compatibility: Highly supportive bra for running and all other high impact activities especially for larger boobs

Runderwear Easy-On Running Bra: on the trails

You have to fasten no less than six hooks to put on the Runderwear Easy-On Running Bra, which may be stretching the meaning of easy a little bit (Image credit: Runderwear)

I found this bra very comfortable for larger boobs – I actually tested a 36F rather than a 34D during 2020/21 when I suddenly needed a huge size for pregnancy and breastfeeding. I’m pleased to say that this bra rose to the challenge of massive and often painful boobage very well, and is now baggy in the cup area, while the chest strap is wonderfully comfy for all-day wear in that larger size. 

Some of the stitching at the front of one shoulder has unravelled itself, as it was worn many times under a running backpack on the trails, but other than that it has stood up well to being the only bra I could use for a year and a half for running, walking, cycling and the odd open water swim. 

The trick to getting it on is definitely to do up the three-hook racerback strap as well as the three-hook chest band. I like that there is adjustment on the racerback with the three hooks; I find the widest setting at the chest and the narrowest setting on the racerback works best. 

I do think the price is high, compared to most of the others here, so waiting for the sales is a good plan. However Runderwear do offer a “Perfect Fit Promise” whereby you can keep exchanging the bra for free until you find the correct fit.
