The original MOSOmerino™ fabric, a fusion of viscose from bamboo and merino, created by tasc performance and trusted by Melissa Arnot on her record-breaking Everest Summitwill also accompany Arnot and protégé Maddie Miller for their 50 Peaks Challenge attempt

(New Orleans, LA – June 30, 2016) tasc Performance, a leader in all-natural performance apparel, is honored to support Melissa Arnot, and protégé Maddie Miller as the team sets out on a Challenge to summit the 50 Peaks of the United States in 50 days. In support of the women’s initiative, tasc has provided bamboo-merino blend base layers alongside financial support to help make the excursion possible.

Arnot, who wore the tasc MOSOmerino™ base layer as she summited Mt. Everest without supplemental oxygen one month ago, became the first American woman to accomplish such a feat and broke (her own) world record for the most summits by an American woman in the process. The professional mountain guide and EMT now has embarked on a new mission alongside guide-in -training and college senior, Maddie Miller, to summit the highest points in all 50 states within 50 days.

“I feel lucky to have a sponsor as supportive as tasc – they are like family to me,” said Arnot. “I can always count on tasc merino/bamboo products to hold up to all conditions without sacrificing comfort. The apparel also never gets smelly due to the natural performance characteristics inherent to the material, and this is something I appreciate since it’s hard to find a washing machine in the mountains!”

“We are very happy to support Melissa and Maddie on their 50 Peaks adventure,” said tasc President Todd Andrews. “Melissa truly represents the authenticity and originality of our brand and it is very gratifying to see our products come to life through her adventures.”

The team kicked off their journey on Monday, June 27th, by summiting one of the most challenging peaks, Denali, in Alaska. Upon completing the summit, they flew to Florida where they were met with a vehicle and supplies. The women will now take on the highest points in all 48 mainland states before taking one last flight to the summit of Hawaii to conclude the adventure. Only 273 people have accomplished such a feat and to do so in 50 days will set a new record.

Since 2009, tasc has been an innovator in performance apparel by helping outdoor athletes, endurance athletes and fitness enthusiasts perform ‘naturally,’ without sacrificing style. tasc looks to nature for apparel function as opposed to chemicals from a lab, evidenced by their line of MOSOmerino™ base layer items which offers a high warmth to weight ratio alongside the inherent performance benefits, including superior odor resistance, moisture wicking and softness. The tasc merino base layers are trusted by Melissa to be a staple during extreme climbs and are also used by fellow mountain guide and humanitarian, Jeff Evans, who actively leads high-altitude rescue teams on Everest for the Travel Channel.

tasc Performance was brought to life in 2009 with one mission: the reinvention of performance apparel. The New Orleans-based, active apparel, company was founded and is operated by the Andrews family, which has a 40-year legacy in the garment industry. Over a 2+ year period of natural fiber research and textile engineering, the BamCo® (patent-pending) fabric finishing process was created. This process combines viscose from bamboo and organic cotton to create fabrics that hit every metric: Performance (moisture wicking, drying rate, UPF 50+), Feel (absolutely amazing), and Durability (color fastness, shape retention, easy care, anti-odor). tasc now has over ten proprietary fabrics that are built for the mission of enhancing the active experience through the innovation of original fabrics.
