I want to buy an arcteryx shell (I'm thinking the theta sv) and I want to get a fleece to go under it so I can wear it like a 3 in one jacket. Since arcteryx does not make a 3 in one would this be a good choice to achieve the 3 in 1 effect?
An excellent choice. This combo will give you the ability to have just the right weather protection across a huge range of conditions, especially on the wet/cold/windy side of the spectrum. The Theta SV and Hyllus are really durable, both in concert and solo. They were designed to work together like a 3 in 1 but with less weight, and better fit.
Thanks Brandon, any suggestions for something to wear under the theta sv for when it's not so cold out say when it's between 35 and 50 degrees? I already own a patagonia R3 High loft fleece jacket maybe that would be best?
The R3 might be a bit warm. 2 suggestions - 1) if you're on the move, you won't need something under the SV besides a nice baselayer (wool or capilene). Other than than, any 200-weight fleece would do just fine in my opinion. I typically use the hyllus with a wool baselayer and a OR light shell. Only ever use the 3 together when we've stopped and its windy and cold (sub 30). Around the city I find I can just toss the hyllus over a flannel and be fine to right about 35. Still works fine below 35, but if it's windy you'll feel a decent chill
