High in the sky.

It's no coincidence that Bell named the all-new Women's Stratus MIPS Helmet after the cloud that rests above all others in the sky because it's designed for women who want to stay protected while adding as few grams as possible to their overall setup. It does so while inheriting many features from the top-tier men's Zephyr, so the Stratus occupies a similarly elevated echelon as its cloud namesake. An aerodynamic shell shape suits the Stratus well to weekend races, but if you're a recreational cyclist who'd prefer to enjoy the scenery rather than ride for time, you'll still benefit from this helmet's low weight and high functionality.

While you're out on the roads, a durable Fusion In-Mold polycarbonate shell protects against stray pieces of gravel and direct impacts, while inside, MIPS technology in the form of a thin inner liner addresses oblique impacts. This inner basket rotates slightly upon impact to absorb brain-damaging rotational energy created in certain crashes.

With Bell's Float Fit dial, you'll also be able to adjust the helmet laterally and vertically for a safe, secure fit around your head, and the adjustable No-Twist Tri-Glide straps on either side of the Stratus stay in place so you don't spend your ride tugging them back in place when you should be concentrating on the roads. As you pedal along exposed roads in mid-summer heat, you'll appreciate the Stratus' 18 vents, which are positioned to give you a welcoming cool breeze as you ride without impacting the helmet's aerodynamic efficiency or protective properties.

  • Stay safe as you push the pace in this cycling helmet
  • MIPS technology aims to minimize injury in certain crashes
  • In-mold shell dissipates direct impacts
  • No-twist side straps stay securely in place
  • Multiple vents keep air moving consistently as you ride
  • Float Fit dial allows for quick, precise fit adjustments

  • Fit: True to size

Disappointing that barely room for sunglasses and could see helmet shape in front while riding.

No Room for Pony Tail

  • Familiarity: I returned this product before using it

If you Rock High Pony this is not the helmet for you. This works with a low pony tail. There is not enough room between the helmet and the lock to fit a pony tail. The strap clasp is very small and difficult. I am returning.
