In reply to The Ex-Engineer:
> At a slight tangent since we are talking about softshells, I have to say that although it looks great I am slightly under whelmed by my RAB Exodus jacket in terms of warmth. Therefore I'm possibly in the market for something with a slightly better blend of insulation and wind/water resistance to wear over the Boreas in more inclement weather.
As I mentioned above, if the Boreas is worn over a short sleeved tee shirt, you won't need much (or any) more than a good windshirt on over, anything more and you'll overcook. Works a treat with a lightweight insulated top in the pack for picnics and long stops.
If you want something more substantial then I'd suggest it should replace the Boreas, not overlayer it.
