Technical Pants. Breathable warmth, stretch comfort, and limited-edition Hiroshi Fujiwara stealth style.
Our latest collaboration with Hiroshi Fujiwara combines trusted backcountry performance with signature Hiroshi style that blends naturally into any environment, from the backcountry to cityscapes. The men's Burton [ak] x FRAGMENT Helium Stretch Insulated Pants are that extra layer that makes all the difference in staying warm on the coldest days. Layer up for a cold day on the mountain. Stay warm at base camp. Stretchy and breathable, they're made for wearing under your three-layer shell pants or bibs, and they're so comfy you'll probably wear them for a lot more than just riding.
| Insulation | Low-bulk insulation adds warmth while staying breathable when you're working hard. |
| Fit | Stretch fabric and waistband let you move easily without feeling restrictive. |
| Features |
Zippered hand-warmer pockets and a back pocket add utility and keep choice items close. Stealth-themed, limited-edition collaboration with Hiroshi Fujiwara, a dedicated snowboarder and legendary Japanese designer. Bluesign® approved materials reduce impact on humans and the planet during manufacturing. |
