Absolutely perfect for layering

Yes, I recommend this

I’m a huge fan of thin layers in winter. These vests are so lovely. Soft and stretchy so they’re perfect under jumpers, fleeces and cardigans. I wear mine underneath the long sleeved version for extra warmth. They’re nice and long too, without being cumbersome. So comfy; absolutely perfect.

Comfy and warm

Yes, I recommend this

These are great to wear under a top to give you an extra layer when it is a bit chilly. They are thin enough material that they don’t look bulky under a top but they also help keep you warm. This is the second time I have bought these.
