How Warm Is The Pursuit Hybrid Fleece?

How Warm Is The Pursuit Hybrid Fleece?

The Pursuit Hybrid Fleece is designed for high-output activity in cold conditions. When moving with a proper layering system, most users will stay comfortable between about 15–35°F, depending on exertion level & conditions.

In milder temperatures it can be worn as an outer layer, and in colder conditions it works best as a midlayer under a shell or heavier insulation.

It's built to keep you comfortable while hiking, climbing, hunting, or traveling in cold environments where overheating is just as much of a problem as getting cold.

How Does The Pursuit Keep You Comfortable While You Move?

The Pursuit Hybrid Fleece was built so you can put it on and leave it on. Traditional fleece can be a bit too breathable for some windy applications above tree line, while windproof jackets often feel too hot during exertion. The Pursuit uses body-mapped fabrics, breathable insulation, and air-permeable face materials to let excess heat escape while still keeping your core warm.

This allows you to stay comfortable during long climbs, cold mornings, exposed ridges, or high-output activity without constantly stopping to remove layers. Instead of overheating and cooling down repeatedly, the Pursuit helps maintain a steady temperature so you can keep moving.

  2. Choose Low Spin or Delicate wash.
  3. Choose Cold Wash & Cold Rinse.

Does the Pursuit Hybrid Fleece run true to size?

The Pursuit Hybrid Fleece fits true to size, but customers who want a close midlayer fit often size down one.

The jacket has an athletic cut — if you plan to wear it as a standalone outer layer over a base layer, order your standard size. If you're primarily using it as a midlayer under a shell, you should order your standard size. Use the sizing quiz on the product page for a personalized recommendation, and remember: your first exchange is always free.

Does the Pursuit Hybrid Fleece come in tall sizes?

Yes, the Pursuit Hybrid Fleece is available in tall sizing from L-Tall through 2XL-Tall, in addition to standard sizes S through 3XL. The tall cut provides extra sleeve and torso length — important for maintaining coverage during overhead movement, pack carry, and climbing approaches where standard sizing often rides up.

What temperature range is the Pursuit Hybrid Fleece designed for?

The Pursuit Hybrid Fleece is designed for active use in temperatures below 40°F (4°C), with real-world use documented down to the low 20s°F when paired with an outer down layer. Its mapped Primaloft® Evolve insulation retains warmth during slower movement and rest stops, while the hybrid grid fleece panels aggressively vent heat while still providing minimal insulation during high-exertion activity — allowing continuous wear without overheating across a wide temperature swing.

Can I wear this Fleece as a standalone outer layer, or is it only a midlayer?

The Pursuit Hybrid Fleece is designed to function primarily as a technical midlayer, but may also be used as a standalone outer layer depending on conditions. During high-exertion activities in cool-to-cold conditions, the DWR-treated 30D stretch-woven nylon face provides enough wind and light moisture resistance for outer-layer use. When temperatures drop or conditions turn severe, the Pursuit Hybrid Fleece layers cleanly under a hardshell or down jacket without bulk or binding.

What should I wear under and over the Pursuit Hybrid Fleece?

Under the Pursuit Hybrid Fleece, wear a moisture-wicking base layer — merino wool or synthetic — to move sweat away from skin. Over it, add a hardshell in rain or wind, or a down jacket for extreme cold or static use. This three-layer system is the foundation of Outdoor Vitals' Mountain Pursuit Line, where the Pursuit Hybrid Fleece is the active midlayer, the Vantage Alpine Down Jacket adds static warmth, and a shell closes the system against weather.

Is the Pursuit Hybrid Fleece good for hunting?

Yes, the Pursuit Hybrid Fleece is an excellent hunting jacket, particularly for backcountry approaches where you alternate between high-exertion hiking and static glassing or sitting. Its Primaloft® Evolve insulation keeps you warm during slow movements and stationary periods, while the breathable hybrid construction prevents overheating on steep climbs and pack-outs. Customers have used the Pursuit Hybrid Fleece on Alaska and Idaho hunts from September through November — as a standalone active layer on high-output approaches, and as a midlayer under a down jacket and shell in colder conditions.

Is the Fleece good for backpacking and fastpacking?

Yes, the Pursuit Hybrid Fleece is purpose-built for backpacking and fastpacking, weighing just 9.4 oz (size M) while serving as both an active trail layer and a camp warmth layer. That versatility means the Pursuit Hybrid Fleece can replace two separate garments in your pack — an active fleece and a light insulator — without sacrificing performance in either role. For ultralight backpacking and fastpacking where every ounce and every layer must justify its place, it's one of the most efficient active cold-weather options available.

Why does the Fleece use two different fabrics?

The Pursuit Hybrid Fleece uses two different fabrics because your body generates and loses heat unevenly — and a single-fabric jacket forces a warmth-vs-breathability compromise that mapped construction avoids. Primaloft® Evolve insulated nylon is mapped to the chest and back where heat escapes fastest. Grid fleece is placed in the underarms and shoulder zones where heat and sweat build up most during exertion. This material mapping allows the Pursuit Hybrid Fleece to be warmer than a standard fleece and more breathable than a standard active insulation jacket at the same time.

What is the Mountain Pursuit Line and where does the Pursuit Hybrid Fleece fit in it?

The Mountain Pursuit Line is Outdoor Vitals' integrated apparel system for rugged, high-output mountain conditions, and the Pursuit Hybrid Fleece is the active midlayer at its core. The full system pairs the Pursuit Hybrid Fleece with a moisture-wicking base layer, the Vantage Alpine Down Jacket for insulated warmth, and the comfort-first Altura Dynamic Pants for unrestricted movement. Each piece is engineered to layer together without bulk.
