Finally! An Adjustable Tracksmith Sports Bra

The Allston gets our top marks for the year as an excellent all-around bra for daily wear as well as longer runs. It has an easy-to-reach hidden chest pocket that can stash keys, cards, cash, and/or your phone.

The bra’s band is brushed with Inverno Blend lining, an Italian micro-nylon and elastane mix that pulls away moisture and is wool-soft. This is the same blend used in Tracksmith’s Allston tights, and feels just compressive enough for support without being too constricting for comfort during long runs.

While the rectangular outline was obvious, our tester appreciated how easy it was to grab her iPhone mid-run. We experienced no chafing during our test period, even in the high humidity and mid-80’s temps of mid-summer on the East Coast.

It has plenty of top-to-bottom coverage that feels like enough space for A- to C-cups, though people with cups sizes larger than that might want a bra with more support.

Perfect for people engaging in higher impact activity or with larger breasts, this compression bra from Brooks helps keep everything in place and prevents uncomfortable bouncing. It’s also convenient, with three pockets that we stuffed gels, a credit card, a house key, and a phone into without feeling extra bulk.

The phone slots nicely into the deep mid-back pocket, and the small pockets on either side were perfect for a credit card, gel, and a key. We found this to be ideal for long-distance training when we need to stock up on gels or keep a credit card handy for mid-run fueling stops, or when we don’t want to carry a handheld but need to stop by a store after the run.

Brooks does an excellent job with its full-coverage bras for larger breasts (the Dare is one of our all-time favorites) and this model is no exception. It has friction-free bonded seams that kept us chafe-free and comfortable, as well as removable cups.

Brooks calls this medium support, but we found the design and coverage to provide a high level of support. Our only critique is that it feels a little tough to take on and off, especially when we are still sweaty from the run.

Finally, a sports bra with a back phone pocket that’s not hard to reach when it comes to dropping in/taking out your smartphone. One of our testers said she loved how Rabbit’s pocket cradled her phone, as opposed to the too snug, too thick compartments often found in sports bras with a similar design. This made it easier for her to grab the phone on the move without contorting into a variety of yoga poses, and it still felt secure enough that she wasn’t worried about it bouncing out.

That same tester, who is a 36D, found she could only wear the bra for short workouts, however. The straps are fairly thin, and dug into her shoulders leaving “not-so-cute” red lines. This may be a support issue, though.

Another tester, who is a 32D, didn’t experience any skin indentations after her runs, so we encourage you to try this bra for a variety of different workouts and distances and determine for yourself where the comfort levels are.

We were stoked on the just-enough compression that didn’t feel suffocating but was supportive enough for moderate-level workouts and runs.

Sports bras are expensive, but we’ve been continually impressed with all of our value picks across the category. We included this one on our list for its bargain price and five-star reviews, as well as the versatile medium impact that provides support for A to D cups. The back pocket is easy to reach and can store your smartphone. And if you’re wearing wired headphones on your next run, you can thread the cords through a bonded eyelet above the pocket.

The soft cotton-like material leaves no indentations on the shoulders, and the high neckline provides extra coverage. This bra is easy to take on and off, doesn’t lose its shape after multiple wears, and comes in a variety of fun colorways.

Janji has made multiple stellar pocket bras over the past few seasons. Several of our favorites have (at least temporarily) been discontinued, but the Ascend is still in-line, and has a sleek design with moderate compression and support for a range of cup sizes thanks to the triple-layer band that minimized bounce without digging into our shoulders.

The back pocket holds a phone securely during high-impact runs, and is easy to access without turning into a contortionist. Those with larger cup sizes might appreciate more compression, but we found that the range of sizes offers plenty of options for a near-custom fit.

Therefore, if you’re looking for a more comfortable everyday bra, we recommend sizing up. If you’d like a more compressive fit for high-impact workouts, go with your normal size. That said, we’ve found Janji to run a little small, so don’t size down.

This bra uses the brand’s Groundwork material, which is smooth next to skin and uses a double-layer for compression and modesty.

Another reasonably priced bra, this Adidas option has a secure front pocket that we felt almost no bounce from, even when we stashed our phone in there for a longer run. The front pocket sits slightly off to the side under the shoulder strap, curving around the front of the bra and protected by two layers of material on the inside. The top of the pocket is reinforced as well, helping hold small items and even a phone in place without feeling extra bounce.

This material is stretchier than other blends, so you can vary your sizing depending on how much compression you want. We have this in two sizes, a smaller size for more support during higher intensity workouts, and one size larger for all-day wear or more laid-back workouts.

Oiselle’s Flyout Bra provides the right amount of compression for support without feeling too tight, and we’ve found the numeric sizing helps the fit of its bras stay right on point. The style has wide, thick straps that don’t create red marks after long wear, and the chest band is wide and smooth.

The phone pocket is between the shoulder blades, and we were able to easily grab it by reaching overhead. And when we don’t need our phone, the bra is fitted so well we never felt any extra bounce or worried about it falling out.

Oiselle’s proprietary “Power Plya” material is soft and has almost a brushed knit feel on the inside, but doesn’t get oversaturated with sweat during hot runs. We also love the wide back coverage here, which lets us wear this as a crop top as well as a sports bra without worrying about exposing too much on our runs or errands.
