  • The Challenge Sailcloth Newport brand is the most recent addition to our highest end sailcloth.

    Newport is a complete product line with three main construction types: All Purpose, Low Aspect and Pro Radial. Newport is produced using the best sailcloth fiber available; Challenge Fiber 104.

    This new product line combines all of the R&D Technology which Challenge has learned from the production of famous brands (such as Marblehead, Warp-Drive and High Mass Fiber Weaves). Challenge has designed constructions with very strong fill 1% numbers, rugged denier combinations for AP applications, and strong radial performance in Newport PR. Fiber 104 can pack more fibers in a sail than competing sailcloth. Challenge has developed a mechanical advantage.

    The results are tight weaves, excellent shape holding, rugged durability and high UV protection. Sailors who need a high quality sail can choose from one of the three Newport lines for trust, quality and fantastic satisfaction with their sail.

 The Future is Now, and it Can’t Wait.

The legacy of Challenge Sailcloth spans four generations in the sailing textile industry.  In 1917, our family founded Howe and Bainbridge, one of the first sailcloth companies in the USA.  In the 1930s, DuPont® invented synthetic polyester and nylon fibers which we used to create the first Cordura® nylon mainsail cloth.  Moving from tar-impregnated cotton sails to technical synthetic textiles started a new era of sailboat racing and innovation.  We’ve been leaders at the forefront of textile innovation for over 100 years.  Looking forward, our focus is entirely on sustainability within the textile industry.

In 2020, Challenge Sailcloth launched a new company called Challenge Outdoor, spearheaded by world champion sailor and technical textiles expert, Hale Walcoff.  Hale had a vision to produce light, durable, and UV resistant materials for the outdoor sports industry using 100% recycled polyester. He wanted to produce fabrics that were best in class for the industry while being environmentally friendly.  Challenge Outdoor is dedicated to reducing real-world carbon emissions and promoting clean textile technology.  As outdoor enthusiasts, it is our duty to tackle the climate crisis.

This project would not have been possible as recently as five years ago, because recycled and natural component manufacturers had not achieved the performance levels required in strenuous and demanding outdoor sports. Thankfully, the global community demanded green tech, and the investment followed.  Moving full speed ahead, our development efforts will be focused on sustainable innovation across our product lines.   This is our new race against the clock and a challenge to the industry.  Solving the climate crisis requires world-wide collaboration and we welcome you to get on board.
