FULL REVIEW

Compressibility
The Alpine AP II performed well, but was not as compressible as some of the other bags in this category, namely the Valandre Shocking Blue, but was warmer than one of the other bags due to the amount of down used to fill the bag. 

Warmth
Along with the Western Mountaineering Lynx, the Alpine Ap III was one of the warmest bags in this category. Besides the Lynx, the Alpine Ap III had the most loft compared to any bag tested in this category. The Ap III has a good fit, meaning it is not too restrictive but maintains flexibility without extra space, thus making the bag quite warm and comfortable. The hood has good adjustment options and is filled with down creating good warmth. I found this bag comfortable at 13F. 

Overall Comfort
The Alpine Ap III has a lofty feel and excellent size. The bag does not have a lot of dead space, but is not restrictive either making it comfortable and warm. I could wrap myself up in the hood and feel warm and comfortable in this bag. 

Durability
The Alpine Ap III did not suffer any noticeable wear and tear and held up very well to the testing phase. The Ap III also held up well to tent condensation and weather. 

Features
The Alpine Ap III utilizes 3D Nanoshell for the shell of the bag and treated Ultra Dry Down insulation to provide excellent protection against moisture from tent condensation or the elements. The Ap III also comes with an oversized neck collar and hood seal, which adds to the comfort and warmth of the bag. An inside security pocket is provided to store items like camera, battery and fuel to protect them from the cold. The Ap III also comes with a Sea to Summit compression storage bag, mesh storage bag and laundry bag.
