Short answer: A normal cap is enough if you wear your hair in a low ponytail or low bun, or if you are happy to pull the tail through the gap at the back. A ponytail cap is worth it if you run or lift with a mid or high ponytail or a bun and want the cap to sit properly without pushing your hair down. Whether it is worth it comes down to how you tie your hair, not how hard you train.
Disclosure: this guide is written by Ponyloop, which makes ponytail caps. We have tried to keep the advice useful whichever cap you end up buying.
Is a ponytail cap worth it for running and the gym?
It is worth it when your hairstyle and a standard cap are in conflict. With a high ponytail or bun, a normal cap either sits on top of the hair, tilts forward, or forces you to move the tie lower. A cap with an opening at the back removes that conflict. If you never feel that conflict, you do not need one.
When is a normal cap enough?
- Low ponytail: the tail can hang below the cap or pass through the back gap.
- Braid: a single low braid usually hangs out of the back without trouble.
- Short sessions: for a walk or a short jog, a slightly awkward fit may not bother you.
- Hair worn down or tucked in: no opening is needed.
Some running caps from sports brands have a slightly larger gap at the back. That is generally enough for a low or mid ponytail only, not for a high ponytail or a bun.
When does a ponytail cap make sense?
- You tie your hair high for training. Many people do this to keep hair off the neck and out of the face.
- You wear a bun. A bun needs space, and a standard cap cannot give it.
- You adjust your cap constantly. If you keep tugging it, tilting it or taking it off between sets, a better fit solves the real problem.
- You do both running and gym. Hair bounces differently in each, and a back opening keeps the cap steady in both cases.
What should you check before buying a ponytail cap for sport?
| Check | Why it matters for training |
|---|---|
| Opening type | Magnetic closures, Velcro strips and crossed elastic bands all work differently. Pick one you can close easily with one hand. |
| Fabric | Look for lightweight, breathable, moisture-wicking material, or mesh for hot days. |
| Size range | A cap that slips during a run is no use. Check the head circumference range and whether a sizing insert is included. |
| Care | Sweaty caps need regular washing. Check the care label before you buy. |
| Exchange terms | Fit is personal. Read the exchange policy before ordering, especially if the shop does not offer refunds. |
Which Ponyloop caps suit running and the gym?
Ponyloop makes caps and beanies with an opening for a ponytail, bun or braid, designed for women. For training, two caps are the most relevant:
- PonyLoop Original: a cap with a magnetic closure on the back, available in Black, Gray, Navy and White.
- PonyLoop Vintage: a trucker cap with breathable mesh and a CrissCross opening, where your hair goes through between crossed elastic bands. It has a washed, worn-in look.
The caps are described as made of recycled polyester that is lightweight, breathable and moisture-wicking, with stretch and UV protection. They are one size for a head circumference of 54 to 62 cm. A black foam insert is included and makes the cap about 2 to 3 cm smaller, intended for heads under 56 cm. To measure, wrap a tape about 1 cm above your ears. Care is hand wash cold and air dry.
What does it cost and how does ordering work?
PonyLoop Original, Vintage and Glitter caps cost 24.99 EUR each. Orders usually arrive within 1 to 3 weeks after payment, and in rare cases it can take up to 40 days. There is no express option, so plan ahead if you are buying for a race or a new training block.
Ponyloop does not offer refunds. Instead there is a voluntary one-time exchange within 14 days, for example if size or color does not suit you, under the conditions on the Returns & Exchanges page. The German store is at de.ponyloop.com and the English store at eu.ponyloop.com.
So, what should you do?
Try your usual cap with your usual training hairstyle. If it fits without effort, keep it. If you keep adjusting it or give up your preferred style to wear it, a cap with a back opening is a reasonable, specific fix.
Frequently asked questions
Can I just wear a normal baseball cap for running with a ponytail?
Yes, if the ponytail is low. A normal cap works with a low ponytail or braid. For a mid or high ponytail or a bun, the cap usually sits awkwardly or forces you to move the hair tie lower.
Does a ponytail cap stay on during a run?
Fit depends mostly on size, not on the opening. Measure your head about 1 cm above the ears. Ponyloop caps are one size for 54 to 62 cm, and an included foam insert makes the cap about 2 to 3 cm smaller for heads under 56 cm.
How do I clean a ponytail cap after a sweaty workout?
Follow the care label. For Ponyloop caps, the care instruction is hand wash cold and air dry.
