The best cap for your ponytail is the one whose opening mechanism matches your hairstyle: a magnetic closure works for changing styles from a low ponytail to a high bun, a CrissCross opening holds especially securely during sport and movement, and zipper or knit designs each have their own strengths. In this comparison, we take an honest, no-nonsense look at the common mechanisms, materials, and prices of ponytail caps, so you'll know exactly which model suits you.
Why doesn't a ponytail fit under a regular cap?
Because a regular cap is closed at the back and only leaves the small crescent-shaped opening above the adjustable strap free. So your ponytail either has to sit very low or gets squashed – with a high ponytail, a bun, or voluminous curls, that simply doesn't work. Many people know the result: the cap sits crooked, presses on the back of your head, or your hairstyle is ruined once you take it off. Caps with a ponytail opening solve exactly this problem. They have a specially designed opening at the back through which your ponytail, bun, or braid can come out at any height – without squashing and without restyling.
What types of ponytail caps are there in 2026?
Four opening mechanisms have established themselves on the market: magnetic closure, CrissCross bands, zipper, and open knit designs.
- Magnetic closure: The back of the cap opens and closes with magnets. This lets the opening adjust to the height of your hairstyle – from a low ponytail to a high bun. The PonyLoop® Original, for example, uses this principle.
- CrissCross opening: Crossed elastic bands hold the cap securely on your head and let your hairstyle out between them. At Ponyloop, the PonyLoop® Vintage and the PonyLoop® Glitter use this design; the US brand VimHue also uses an X-shaped band design on its Sun Goddess models.
- Zipper: The Canadian brand Ponyback fits a zipper into the back of its caps that can be opened for your hairstyle and looks like a classic cap when closed.
- Open knit design: Brands like Ponyflo from the US make stretchy knit caps with a wide, permanently open cutout at the back of the head.
All four approaches serve their purpose – the differences lie in handling, look, and how flexibly the opening adapts to different hairstyle heights.
Magnetic closure or CrissCross – which is better for you?
The magnetic closure is the most flexible solution for changing hairstyles, while the CrissCross opening is the most secure during lots of movement. If you wear a low ponytail in the morning and a messy bun in the afternoon, you want an opening that adjusts in seconds – that's exactly what the magnetic mechanism on the Original is made for: put it on, pull your hair through, snap the magnets shut, done. When jogging, cycling, or at a festival, on the other hand, the CrissCross principle wins out: the crossed bands sit elastically and keep the cap in position even when your ponytail swings with every step. There's no wrong choice here – it comes down to what your day demands.
Which material works best for summer, sport, and everyday wear?
For summer, lightweight, breathable cotton is the best choice, ideally with UV protection. A tightly woven brim protects your face and scalp from the midday sun – an often underestimated point, especially for outdoor sport. The Original is lightweight, breathable, and offers UV protection; the Glitter is made from 100% cotton with a hand-sewn finish if you like something more eye-catching. If you prefer the used look, the Vintage comes in a deliberately distressed fabric – that, by the way, is a design feature, not a flaw. For cold days, the ponytail-opening principle is also available as a beanie with a silky lining, like the PonyLoop® Silk Beanie.
What do ponytail-opening caps cost in comparison?
At Ponyloop, caps currently cost 24.99 € – that applies to Original, Vintage, and Glitter; the Kids Beanie is 19.99 € (as of July 2026). Prices from other providers vary depending on brand, material, and origin. Important for a fair comparison: orders from brands outside the EU can add international shipping costs and possibly customs fees on top of the product price. So always calculate the total cost, not just the price on the label. You'll find Ponyloop's delivery terms for Germany, Austria, and Switzerland laid out transparently in our Shipping & Payment Information.
Does one size really fit every head?
Yes – provided the cap covers the 54 to 62 cm head circumference range and can be adjusted smaller. All PonyLoop® caps are one size, fitting 54 to 62 cm; a black foam insert (sizing clip) is included, which reduces the cap by about 2–3 cm. That's ideal if your head circumference is under 56 cm. To measure, wrap a tape measure around your head about 1 cm above your ears – more on that in our FAQ.
Conclusion: Which cap is best for your ponytail?
The best ponytail cap is the one whose mechanism matches your hairstyles: the magnetic closure of the Original for maximum everyday flexibility, the CrissCross opening of the Vintage or Glitter for secure hold during sport and festivals. Objectively speaking, zipper and knit designs from other brands are functional solutions too – just check total costs and delivery there.
