I'd say I never really have a problem keeping my core warm. I'm also pretty active so I don't see why my circulation would be lacking. Reynaud's seems like it has some simple solutions to combat so I'll give those a try and see how it goes.

For now though I'll try a new combo of Smartwool liners, Fox River wool mitts and MLD rain mitts. Soon I'll be heading off on a trip and will spend the last three weeks on the GR5. Good ample testing grounds I suppose.
