Nike ACG Wolf Tree 1/2 Zip Top - Polartec® Fleece for Trail-Ready Warmth

First seen as part of the Nike ACG Wolf Tree collection and tested in Oregon, USA, this top was born from a simple need — a warm layer that adapts through different parts of the day on trail. Polartec® fleece delivers lightweight yet breathable warmth, loose fit allows easy layering or solo wear, and considered details make it genuinely functional for outdoor adventures.

Polartec® Fleece for Breathable Warmth

Polartec® is an ultrasoft fleece that holds warm air in whilst letting moisture escape, helping keep you dry during active outdoor efforts. Lightweight with optimal breathability, this construction keeps you comfortable across varied activity levels, from sustained effort on trail to stationary moments when you need warmth to linger. The loose fit accommodates layering underneath or wearing on its own as temperatures shift.

Trail-Ready Construction Details

Shoulder seams are eliminated for more comfortable pack carrying during trail adventures. Half-length zip allows extra ventilation when effort and temperature increase. Zippered pockets keep essentials secure during movement on technical terrain. Each detail was considered specifically for outdoor use rather than adapted from standard fleece construction. 100% polyester construction.

Is the ACG Wolf Tree 1/2 Zip Right for You?

Built for outdoor athletes who need a warm, breathable layer that genuinely adapts across the day. Polartec® fleece holds warmth during rest stops and releases moisture during active effort, the specific challenge of outdoor activities where output varies constantly. Eliminated shoulder seams make a noticeable difference when carrying a pack across longer trail efforts. Half-zip ventilation handles temperature regulation on the move. Zippered pockets keep essentials secure on technical terrain where open pockets become a liability. If you want a lightweight fleece layer that's been considered for trail use rather than just worn on it, the Wolf Tree delivers.
