Fabric & Performance

- Insulated Panels across the chest and upper back trap warmth at the core
- Wind-resistant shell keeps cold gusts out during exposed sections
- Breathable stretch panels allow moisture to escape during effort
On the Run
We tested the jacket during frosty morning runs and cool evening tempo efforts. Key takeaways:
- Kept the core warm without overheating
- Sleeves and underarms vented well—never felt clammy
- Blocked headwinds effectively on canal paths and ridgelines
- Fit snug without impeding arm movement or stride
This isn’t a post-run coffee shop jacket—it’s designed to move, and it performs best when you do too.
Fit & Comfort
- Athletic cut hugs close without compression
- Elasticated cuffs seal warmth without riding up
- Adjustable hem allows micro-fit tuning
- Moves with you, thanks to slight stretch throughout critical zones
The Hyperchill fits true to size, but those between sizes or layering over bulkier baselayers may want to size up.
Key Features for Runners
- Zoned insulation: Keeps you warm where it counts
- Wind resistance: Reduces windchill on brisk runs
