See some of the people that are the best at what they do, and love using clothing and gear with 37.5® Technology to get it done.


IFMGA/AMGA Mountain Guide

Originally from Connecticut, Chris Marshall has found his home in the mountains of the west, but only after he was done cutting his teeth on the icy ski slopes of New England. It was Marshall’s first overnight backpacking trip to the Appalachian Mountain Club’s Garfield and Zealand Falls huts did he fall in love with the untrammeled landscapes of the outdoors. In 2003, Marshall graduated from college with a double major in Wilderness Leadership and Geography. While studying in Arizona, he took advantage of the year-round mountain biking and rock-climbing. Marshall has been guiding and instructing throughout Alaska and the west since 2006. He is well versed on rock, snow, and ice – now primarily working in central Idaho in the winter and the Pacific Northwest in the summer. Marshall earned international Mountain Guide credentials in 2016 when he became certified as an American Mountain Guide and a licensed mountain guide through the International Federation of Mountain Guide Associations (IFMGA). That is the highest standard of mountain guiding in the world. He became the first 37.5 Pro Team member – now a big fan of Carhartt’s base layers and Adidas Outdoor’s Terrex fleece.

Jack Hessler grew up in Lincoln, Massachusetts. He first started snowboarding at Stratton, Vermont & Nashoba Valley, Massachusetts. Fortunately for him, his family moved to Jackson Hole, Wyoming in 2009, where he fell in love with the big mountain feel. He and his brothers joined the Jackson Hole Snowboard Team. Hessler says he owes his snowboarding abilities to the older guys and coaches that helped raise him. Fresh out of high school, Hessler enrolled at the University of Denver where he studies psychology all while riding for the DU Freeride Team. In 2017, Hessler and the freeride team won the Red Bull Bracket Reel Challenge.


Rock Climbing

Claire Bukowski is a 19-year-old climber from Tucson, Arizona. Bukowski started her competitive climbing career in 2009 – since then her love and appreciation for climbing continues to grow. She enjoys spending time traveling to new and unique places to boulder, sport climb and trad climb outside. A favorite spot for Bukowski is Bishop, California. Bukowski describes it as an absolutely beautiful, small cozy town tucked behind a massive, sweeping, snow-capped mountain range. The perfect climbing get-away: just a short drive out of town is an incredible amount of world class climbing. Besides climbing, Bukowski enjoys dog spotting, singing during car rides and re-watching her favorite television series such as Seinfeld and Rick & Morty. Bukowski’s favorite climbing garment featuring 37.5 Technology is the Adidas Terrex fleece. Good fit, warm and super cute. You can check out the Adidas Terrex line here.

Julie Parker


Outdoor Enthusiast

Julie Parker was born and raised in in Seattle. As a little girl, she was allowed to roam the forests of the Pacific Northwest – in turn revealing her love for the outdoors. Early childhood memories include skiing at Snoqualmie Pass while wearing a trash bag as an improvised rain jacket and learning to pee outside while hiking to glacier fed lakes in the Cascades. After leaving Seattle, Parker made her way across the Atlantic where she spent several summers guiding tours through the Europeans Alps, climbing as many peaks as she could on her days off. Parker later moved to Telluride, Colorado where she continued working as a climbing guide, while finding off days to ski. Parker now resides in Salt Lake City, Utah and fosters a healthy outdoor lifestyle revolving around climbing, backcountry skiing, trail running and homemade cinnamon rolls. She lives with her husband and personal barista, Chris, and their coydog, Chief.



Romi Kristl didn’t let growing up in the coastal town of Monterey, California keep him from the mountains. Kristl first spent time on the mountains at the ripe old age of 2. When he was learning to snowboard, Kristl also spent time surfing and skateboarding – he mentions that both activities influenced his style as a snowboarder. Kristl spent years making trips to Lake Tahoe, but finally his dream became a reality when the opportunity arose to move to Truckee, California and claim Squaw Valley as his home mountain.

At age 22, Kristl has multiple top 10 finishes and has won three international Freeride World Qualifying stops, including two in Verbier, Switzerland. Kristl is hungry for a spot on the Freeride World Tour. When he’s not training, riding backcountry lines, or traveling for contests Kristl is studying International Business at the University of Denver, where he is on the Dean’s List. Kristl also rides for the DU Freeride Team. In 2017, Kristl and the freeride team won the Red Bull Bracket Reel Challenge, earning them a trip to Alaska.
