Re: Re: layering conclusions
Makes sense to me. The obvious flaws in "fleece" over windshell are wind and moisture. In terms of wind, I have always tried to approach this with a lower CFM garment than the wind laye...

Re: Re: Re: Walk
Hey Rob: No, I was suggesting that we try putting the fleece under the second skin for the first half of the workout, then taking it off and putting it on the outside for the second half, and se...

Re: Re: Sala's testing: and challenging the conventional wisdom
Patrick: I don't know the air permeability of Frogg Toggs, but my understanding it that all of their materials are "waterproof/breahable", which almost guarantees that they will ha...

Re: Walk
Rob: Very interesting. Thank you for your insight. Your second test, where you overwhelmed the system, is very interesting. First, I am theorizing that it was not very windy, or I would think t...

Re: Re: Well...that was quick. Sierra Designs Cloud System seems to be no more.
All: Mike Glavin from Sierra Designs here. The Cloud Layering system indeed sold poorly. The rainshiell (Airshell) in particular was deemed over-expensive for an item with limited durability. ...
