Tasc Performance, a leader in all-natural performance apparel, will support Melissa Arnot and protégé Maddie Miller as they set 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 make the excursion possible.

Arnot, who wore the Tasc while summiting 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 up 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 can always count on Tasc products to hold up to all conditions without sacrificing comfort,” said Arnot. “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 began their50 Peaks journey on June 27, 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 253 people have accomplished such a feat and to do so in 50 days will set a new record.
