Push harder, stay warmer, breathe easier — that’s what the Montane Mens Dart XT Zip Neck delivers when the cold closes in. Built as a high-alpine or expedition-grade base layer, it doesn’t just sit under your outer shell — it works actively with your body.

At its heart is Apex Thermo Eco (160 g/m², 88% recycled polyester / 12% elastane) with a brushed back that gives softness next to skin while maintaining excellent moisture-wicking performance. Four-way stretch ensures your movement is never restricted — whether you’re scrambling rock, carrying a pack, or layering under a jacket.

Odour control is handled by a Polygiene treatment, meaning you can wear it multiple days in demanding conditions without the stink factor. The ¼-length YKK reverse coil zip gives you a quick ventilation outlet when you heat up, and the low-profile seams keep things comfortable and snag-free.

At just 200 g (size M) and with a generous back length (≈ 70.5 cm) to help keep drafts out, this Montane Mens Dart XT top hits a sweet spot between insulation, versatility, and comfort.

Why it’s a must-have: because it’s not just warm — it’s smart. Our Montane Mens Dart XT thermal t-shirt actively regulates microclimate, moves with you, resists odour, and won’t feel stifling when you push your pace. For mountaineering, ski touring, winter treks or any cold-weather activity, the Dart XT is the kind of base layer you won’t regret investing in.
