THE PERFECT JACKET FOR ADVENTUROUS SOULS DelSur is made to traverse life's adventures. This go-to jacket gives you the right warmth without overheating. Climbing, Hiking, Mountain Biking, and Office'ing - DelSur performs in the wild, all while keeping you looking and feeling great. DelSur, the Active 4-way Stretch MidLayer Breathes when you are working A layer that warms up without being bulky Stretches with you in all the right places Male and Female Fits, so you look good Sheds water when the unexpected happens Has lots of pockets, even one's you can't see What's Different? With sustainability at the forefront of our minds and performance as the foundation, we set to work on developing the best combination of materials for your DelSur. BAMBOO Using the anti-microbial properties of organic bamboo, we've reduced the smelly bacteria that can get trapped in insulation. GRAPHENE As a legit super-material developed for space exploration, graphene transfers heat quickly and efficiently, which means distributed heat. 4-WAY STRETCH RIPSTOP Our top-line 4-way stretch ripstop fabric for the shell maximizes durability and mobility. YKK ZIPPERS Only the best of the best, tried and true interlocking YKK zippers would do. We created two distinct styles, the Pullover (half zip, no hood) and the Jacket (full zip, with hood). ENJOY THE WILD, WITHOUT WORRYING ABOUT THE WEATHER Flow Vents: The right vents in the right spots helped reduce that 'swamp back' feeling we usually feel when active in a jacket. Weather Shield: DelSur will keep you dry during those surprise showers. Extra Stretch: You'll never feel restricted in the DelSur - the materials are stretchable and lightweight (those two never seem to go together)
