Men's Fleeces & Sweaters
READ: Your Guide To The Layering System
Technical fabrics like Polartec® wick sweat efficiently, keeping you dry when you're pushing hard on steep ascents. Stretch panels at the sides give you freedom of movement during scrambles or when reaching for holds, and high collars seal out drafts that creep down your neck. You'll appreciate how quickly fleece dries, far faster than cotton or down that stays wet for hours.
Weight matters when you're carrying everything on your back. Microfleece options compress small in your pack, ready to deploy when you stop moving and need an extra layer fast. Heavier fleeces deliver serious warmth for winter camps or belaying sessions where you're standing still in freezing conditions. Zipped hand pockets secure essentials, and reinforced shoulders withstand pack straps without wearing through. Leading brands like The North Face and Patagonia offer fleeces that last seasons of hard use, maintaining loft and performance after countless washes.
What fleece style should I choose? Full zip fleeces give you complete ventilation control; open them wide on steep ascents or seal them tight when the wind picks up. Half zip pullovers sit smoothly under climbing harnesses and pack hip belts without bunching, making them ideal for technical terrain. Quarter zip styles deliver the same clean fit with just enough venting for temperature regulation. Hoodies add instant head protection when the weather changes, while crew neck sweaters layer seamlessly under waterproof jackets. Merino wool jumpers bring natural insulation that resists odours across multi-day trips, and technical sweatshirts bridge the gap between casual comfort and performance needs.

The best men's fleece jacket depends on your activity level and conditions. Lightweight grid-back fleeces work brilliantly for high-output hiking and trail running, while thicker pile fleeces deliver serious warmth for winter camping or standing around in cold weather. Look for Polartec fabrics from brands like The North Face or Patagonia for proven performance that lasts seasons.
Heavyweight fleece jackets provide excellent insulation for winter when worn as mid-layers under waterproof shells. Thick pile fleeces handle temperatures down to freezing when you're active, though you'll need additional layers for extreme cold or when stationary. Fleece works best in dry cold conditions rather than wet weather, where waterproof insulation performs better.
Turn the jacket inside-out, use cold water (30°C max), and a mild detergent (no fabric softener). Opt for a gentle cycle or handwash. Air-dry flat or hang—avoid tumble drying. For stains, pre-treat with a powdered soap solution.
Fleece weight is measured in grams per square meter (g/m²) and indicates the fabric's level of insulation.
- 100-weight is a light, highly breathable fleece, ideal as a mid-layer for high-intensity activities or as a standalone layer in mild conditions.
- 200-weight is a versatile, mid-weight fleece that offers a good balance of warmth and breathability for a wide range of temperatures and activities.
- 300-weight is a heavy, exceptionally warm fleece designed for very cold conditions and low-intensity activities where maximum insulation is required.
Polartec® is a specific brand of high-quality fleece known for its durability, insulation, and pill-resistance. It is made from premium polyester yarns knitted and then put through surface-finishing techniques to create a soft, lofty material that traps body heat effectively. Many Polartec® fabrics are now made from recycled materials, such as PET plastic bottles.
A technical fleece is designed for optimal performance during outdoor activities and often features moisture-wicking properties, stretch fabrics for improved movement, and strategic panelling. They are highly breathable, regulating body temperature during exertion. Standard fleeces prioritise comfort and warmth for casual, everyday use.
The zip style significantly impacts a fleece's versatility, ventilation, and weight :
- Full-Zip offers maximum ventilation and is the easiest to take on and off, making it ideal as a versatile outer layer or for activities with varying intensity levels. However, the full-length zip adds weight and can be a point of heat loss.
- Half-Zip/Quarter-Zip. These pullover styles are lighter and more packable due to the shorter zip. They provide good ventilation options while minimising weight and bulk, making them excellent for streamlined layering systems in activities like climbing or running.
Lightweight fleeces (100-200 weight) suit three-season hiking and high-output activities. Midweight fleeces (200-300 weight) handle cold autumn and winter hiking when you're moving steadily. Heavyweight fleeces (300+ weight) provide maximum warmth for winter camping, belaying, or low-output activities in freezing conditions.
Your fleece should fit comfortably over base layers with room to move freely, but not so loose that cold air circulates inside. Sleeves should reach your wrists without riding up, and the hem should cover your lower back when reaching overhead. If wearing as a mid-layer, ensure it fits under your waterproof shell without bunching.
