Adjust the Air. Control Your Warmth.
Built for changing temperatures and shifting effort levels, the N01 Aero-Cell Thermal Vest puts warmth in your control. Its Aero-Cell™ system uses an adjustable air chamber to change the amount of insulating air around your core, while zoned thermal insulation, a breathable back panel and a wind-resistant outer layer help maintain thermal balance on the run.

Control Your Warmth - Aero-Cell™ Adaptive Climate System
Add air when you need more insulation. Release it when conditions warm up or your effort increases.
The adjustable Aero-Cell™ chamber changes in volume as it inflates, creating a thicker layer of insulating air around the core. This lets you fine-tune warmth as temperatures and intensity change, without adding or removing an entire layer.
Adapt Your Layer
The Aero-Cell™ layer is removable, making the vest easier to adapt to different temperatures, training intensities and layering needs.
Use the complete system when you need adjustable insulation, or remove the Aero-Cell™ layer for a lighter, simpler setup.
Keep Your Core Warm
Zoned thermal insulation is placed around key areas of the core to retain warmth where runners need it most.
The insulated construction works alongside the Aero-Cell™ system, helping hold warm air close to the body and providing a consistent thermal foundation as conditions change.
Release Heat Where It Builds
A lightweight stretch panel across the back improves breathability and allows excess heat and moisture to escape as your effort increases.
By concentrating insulation around the core while increasing ventilation across the back, the vest helps maintain a more balanced body temperature during running.
Keep Cold Air Out
A lightweight, tightly woven outer fabric helps block cold wind around the core while maintaining the low-bulk feel needed for running.
It provides protection from wind without turning the vest into a heavy insulated layer.
Lightweight and Packable
Designed to deliver warmth without unnecessary weight, the vest weighs approximately 139 g in size M with the Aero-Cell™ layer, and 88 g without it.
Its lightweight construction makes it easy to carry and pack away when conditions change.
Stay Visible After Dark
Reflective details improve visibility in low-light conditions, adding an extra level of safety for early-morning and nighttime runs.
