Founding Story
Miss Mayfly® is the world's first fishing and wading gear brand created exclusively to fit women of all shapes and sizes. Following a traumatic injury that resulted in multiple spinal and muscular injuries, founder Kimberly Ranalla struggled with the physical limitations and depression that often accompany chronic pain.
2 years into Kimberly’s recovery journey, a friend who believed fishing was an activity she could do, introduced her to wade fishing, where she experienced something unexpected. The intense focus on her fishing line while standing in moving water, combined with the gentle physical movement required by the sport, became an important part of her recovery. Over time, fishing restored not only her mobility, but also her outlook on life.
As Kimberly's passion for fishing grew, so did her frustration with the equipment available to women. The heavy, restrictive waders designed primarily around men's bodies limited movement, added unnecessary weight, and aggravated the very injuries she was working to overcome.
Wanting to share her newfound passion with her daughter, Kimberly searched for properly fitting waders, only to discover that suitable options simply did not exist. That experience revealed a much larger industry problem. Women anglers were expected to wear equipment designed primarily for men, leaving millions underserved by the fishing industry.
In 2016, Kimberly founded Miss Mayfly® to change that.
Today, Miss Mayfly® develops innovative fishing and wading gear engineered specifically around women's anatomy and movement, with a focus on improving fit, and performance. Through proprietary sizing technology, women-specific product design, and a deep understanding of the female angler, the company has become a recognized leader in women's fishing gear, serving customers throughout all fifty states, Canada, and Europe.
"At Miss Mayfly®, we strive to provide the best in fit, comfort and stability while ensuring the ultimate strength and durability of our products.
Driven by a passion for inclusivity, Miss Mayfly has made significant strides in making fly fishing more accessible to all. With an unwavering commitment to our mission, we aspire to continue breaking barriers, fostering inclusivity, and transforming the future of fly fishing."

Our Journey
2016 | A Vision is Born
Following her recovery through fishing, Kimberly Ranalla recognized a much larger problem—women were expected to wear gear designed primarily for men. After discovering there were no properly fitting waders for herself or her daughter, she founded Miss Mayfly® to create fishing and wading gear engineered specifically for women. What began as one woman's search for a better fit became a mission to change the industry.
2018 | The First Women's Wader
After two years of research and development, Miss Mayfly® introduced its first women's chest wader. Built around Kimberly's proprietary sizing methodology, it quickly earned recognition for its superior fit, comfort, and performance. The launch established Miss Mayfly® as a pioneer in women-specific fishing gear.
2019 | Growing the Brand
To meet increasing demand, Miss Mayfly® entered a strategic partnership with Ranger Outdoors. The partnership expanded manufacturing capabilities, strengthened the supply chain, and introduced the brand to a broader outdoor market. It marked the beginning of Miss Mayfly's® national growth.
2021 | The Award-Winning Moxie™ Collection
Miss Mayfly® launched the award-winning Moxie™ Collection, featuring the Moxie™ Chest Wader and the industry's first women's waterproof wading pant. The collection introduced new innovations in fit, adjustability, and performance while continuing to raise the standard for women's fishing apparel.
2022 | The First Women's Wading Boot
The Moxie™ Wading Boot became the first wading boot designed specifically around a woman's foot. Its introduction filled another long-standing gap in the industry and completed Miss Mayfly's® first women-specific wading system.
July 2023 | Founder Ownership Restored
Kimberly Ranalla repurchased Ranger Outdoors' ownership interest, returning Miss Mayfly® to full founder ownership. With complete control restored, the company refocused on its long-term vision of innovation, inclusive sizing, and serving women anglers around the world.
2025 | Innovating Through Change
Despite rising tariffs and industry-wide supply chain challenges, Miss Mayfly® continued investing in the future. Development of the EVO™ Essential Chest Wader was completed, work began on the Moxie™ 2.0 Collection, and specialty sizing expanded to better serve hard-to-fit women.
