Hybrid Active Insulation Built for High-Intensity Movement in Harsh Conditions
Stay warm without overheating in the Pursuit Hybrid Fleece, our most advanced breathable fleece layer yet. Designed as both a lightweight midlayer or outer layer, it offers exceptional temperature regulation and moisture management during high-exertion activities in cold or harsh environments. Whether you're backpacking, hunting, alpine hiking, or fastpacking, this hybrid fleece delivers mapped insulation and breathability where your body needs it most—so you can stay moving longer without swapping layers. This high emphasis on breathability allows you to wear it all day.
Key Features:
- Hybrid Construction for Optimal Performance:
Dual-fabric system combines Primaloft® Evolve active insulation and stretch-woven nylon in the core with grid fleece in high-mobility zones. This strategic mapping ensures the perfect balance of warmth, breathability, and freedom of movement. - Engineered for Temperature Control on the Move:
Built to be worn continuously below 40°F while in motion, the Pursuit Hybrid Fleece keeps you dry, comfortable, and ventilated without constant layering changes. - Ultra-Breathable, Lightweight Protection:
With excellent air permeability and weighing under 10 oz (size L), this layer lets heat and moisture escape while offering moderate wind and water resistance to keep you protected during variable conditions. - Movement-Ready Features: An athletic fit, generous half-zip, form-fitting hood, thumb loops, and lowered rear hem ensure coverage and comfort during dynamic movement.

Body-Mapped Hybrid Fleece Technology
The Pursuit Hybrid Fleece is constructed of hybrid fleece fabrics that are configured in a body-mapped position to maximize warmth, breathability, & versatility.
The high-pile PrimaLoft® Evolve fleece is extra warm, especially when paired with our 30D stretch-woven Nylon. This Nylon is used as a face fabric, and this combo is designed to cover core areas of your torso to maintain comfortable body temperatures in harsh conditions.
To balance warm with breathability, we've used a high stretch grid fleece with a smooth outer face in areas like your arms, underarms, & lower torso. This grid fleece stretches more than the high-pile fleece and allows for more ventilation. It's an ideal fabric for dumping excess heat when necessary.
After 2+ years of testing, we've locked in the optimal arrangement for these 2 fleece fabrics to work side by side in keeping you completely comfortable during high exertion activities in cold conditions.

"I'd buy five of these if sold and take them on everything. I was apprehensive for cold hunts that it would be too light, but I didn't find that to be the case at all. I wore them all from sheep hunts in August and September in AK to late season elk and deer"
"I used this in September in Alaska/Idaho and October/November in Idaho. Loved it over a base layer and under another shell or puffy layer. I have been using it for early morning runs and hikes in cold weather. It really shines while active."
"I see myself using this on most fall hunts in Alaska. I wear with a backpack while hiking and climbing in all but the warmest temps. I will definitely need to get another one in the future, as I see myself using this all the time."
"I wear this with a base layer when it’s below freezing here hiking but it can still get pretty toasty so it’s a great Insulation layer for early season as well"
"I have worn it sitting on my ass in 10 inches of snow in 20 degree temps (with the puffy). I have also worn it on high exertion backpacking trips and pack-outs.
It was perfect. I am amazed at how well this performs in a huge range of conditions."
"Mid layer fit was perfect. Arm and torso length were good. Zipper was a great length. In general I would not change the fit."
Body Mapped For Active Pursuits
When being active on the trail overheating is extremely common. You find yourself stripping off layers, building up sweat and struggling to find a zone of comfort. The Pursuit Hybrid Fleece has mapped fleece layers to find that perfect balance that takes the edge off the wind, keeps key areas of the body warm, and allows the body to exhaust heat as you build it up and move.

All Day Comfort & Temp Regulation
Breathable fabrics that stretch allow for not just more warmth and comfort, but also temperature regulation.
Highly specialized high loft and grid fleeces paired with air-permeable Japanese nylon fabrics can exhaust heat and moisture more efficiently.
Enjoy all-day comfort whether you're hiking high ridges or running in early morning light.
Ultralight & Versatile Design
Ultralight designs often ensure you take them to more places. Compact and light when in the bag and highly functional when on the body, the Pursuit Hybrid Fleece gives you warmth against cold mornings and winds, quick drying materials for when you work up a sweat climbing over that next ridge, and incredible comfort with stretchable, soft materials.

Hybrid materials. Hybrid uses. One layer to do more.
The Pursuit Hybrid Fleece is your go-to for lightweight warmth, maximum breathability, and high-performance versatility.
