From summer to winter, and everything in between, we make layering easy and comfortable.

Bamboo base layers that insulate and breathe without the odour or itch of traditional thermals

O2wear clothing is designed for layering. Our tops are fitted in style, long in the body so they can be tucked in or worn out over pants. Try layering our tops under a sleeveless dress when the weather gets cooler, roll them up and take them when you go travelling (no ironing necessary, odour resistant for multiple days wearing) or wear them as a comfy basic for everyday casual wear. They're perfect for the over airconditioned office in summer, great as an additional layer of warmth in winter and can provide that bit of cover you might need if your top is see-through or low cut.

Often called thermals, long johns, spencers or base layers, we call our range layering basics.
