The Rab Nexus Pull-On Fleece is a lightweight, breathable midlayer designed for active use in cool conditions. Whether you’re hiking in the Lakes, scrambling in Snowdonia, or layering up for a winter walk, the Nexus offers warmth without bulk — and comfort without compromise.
Made from Thermic™ G stretch fleece, it’s soft against the skin, easy to layer, and built for movement. With a deep venting zip, low-profile seams, and a minimalist design, it’s become a go-to fleece for walkers, climbers, and mountaineers who value simplicity and performance.

Fit and Comfort
Rab’s regular fit strikes a balance between freedom of movement and layering efficiency. It’s close enough to trap warmth, but roomy enough to wear over a baselayer and under a shell.
- Stretch fabric moves with you — ideal for scrambling or reaching overhead
- Flatlock seams reduce bulk and prevent chafing under pack straps
- Double cuffs sit snugly at the wrist without riding up or interfering with gloves
- Collar is soft and low-profile, offering warmth without stiffness
The Nexus Pull-On feels tailored for active use. It doesn’t bunch, sag, or restrict movement — even during long days on the hill.
Breathability and Warmth
The Thermic™ G fleece is designed to regulate temperature during high-output activity. It’s warm enough for cool mornings, but breathable enough to wear through the afternoon.
- Grid backer enhances airflow and moisture management
- Deep chest zip allows rapid venting on steep climbs
- Quick-drying fabric sheds moisture fast after exertion or light rain
It’s not windproof — but that’s by design. The Nexus excels as a midlayer, pairing perfectly with wind shells or waterproof jackets when conditions turn.
Storage and Features
The Nexus keeps things simple:
- Zipped chest pocket fits a phone, compass, or snack bar
- No hand pockets — reducing bulk and improving layering compatibility
- YKK Vislon zip is smooth, glove-friendly, and opens deep for ventilation
While minimalist, the features are well thought out. The chest pocket is mesh-lined for breathability, and the zip guard prevents irritation at the neck.
Durability and Build Quality
Despite its lightweight feel, the Nexus is built to last:
- Abrasion-resistant outer handles pack straps and rough terrain
- Reinforced stitching holds up to repeated use and washing
- Pilling is minimal after months of wear, though some users report light fuzzing over time
It’s not a heavy-duty fleece, but it’s tough enough for regular hill use and travel. After months of testing, ours showed no signs of sagging or seam failure.
