Sitka vs SG Sythetic Insulation Layers, And When to Use Them 

Hi Craig. Thanks for the comment! We agree. There's a lot of versatility and performance variation in the mid-layer category. - Forest

Thanks for the comment, Michael!

I think the Ambient, or Cirque Lite will both be great options. The Cirque Lite will be a little warmer, the Ambient will be a little more breathable.

Perfect. Thanks brotha!

The Kelvin Lite Down is going to be quite different from the Cirque... It will be warmer, but less breathable since it is a down insulation layer. The Kelvin Lite Down is not our favorite piece due to the loud/crunchy face fabric, but it does function quite well. For me, I would go with the Cirque or Aerolite before I went with the Kelvin Lite Down. I like to go with synthetic options if I want to be at all active in the jacket, and I want my down jacket to be thick and warm for times when I am not moving. Hope this helps - Brady

@@gearfool thanks for the info. I’m looking at a synthetic vs down option for times when I am not moving. I have my active layers covered, so now looking for a static option.

@@readyme For what it's worth, I would recommend basing your synthetic vs down decision on the likelihood of moisture and precipitation in the region you'll be adventuring. The warmth-to-weight ratio of down insulation really can't be beat and it's increased packability is an added bonus. With that being said, perhaps synthetic insulation is the way to go for your region if there's a lot of moisture...or frequent possibility thereof. - Forest

They will be very similar in actual warmth, the Cirque is thicker so you'll have a warmer "feel" but the Aerolite will hold similar heat with less bulk.

Hi Chris. We appreciate it! I'm wearing the SITKA Core Lightweight Hoody in this video, and Brady is wearing the SITKA Heavyweight Hoody. - Forest

Now there's a subjective question that can be difficult to answer accurately, but I'll give it a try having previously worn both products. For myself in "moderately cold" climates, I would suggest that the SG Grumman Goose Down Jacket offers no less than 25% greater warmth. Often a bit more in some climates. - Forest

I think most people will agree that the aerolite is a bit warmer, but the Cirque will have better DWR treatment, and it'll probably be more abrasion resistant. However, both will serve the same purpose. I like the aerolite myself due to the small pack size. -Brady
