Compressibility
The 650 fill down and the spacious fit of this bag do not make it overly compressible.  The Blue Kazoo took more than average work to get into a medium sized compression sack. 

Warmth
The 650 plus loft down made this bag warm into the high 20’s, but for any temperatures below 25 F, I was forced to add layers of clothing to be able to sleep.  This wider bag added comfort but also made it harder for my boy to warm up in the bag, and ultimately was colder than any other bag in this category.  

Features
The Blue Kazoo comes with 650 fill ProDown, which is the North Face treated water repellent down. This down provided good loft and handled condensation and the elements well. The oversized and comfortable hood adjusted easily and when tightened around the head and neck remained comfortable and always kept my head warm, making it one of the best hoods in this category. The Blue Kazoo has big down draft tubes that blocked the wind and cold very well.  

Overall Comfort
The Blue Kazoo has a large hood and roomy upper body section making it very comfortable.  The foot box has plenty of room and allowed me to sleep with my feet comfortably in any direction. The inner liner is soft and the down is cozy.    

Durability
The Blue Kazoo was durable during the testing phase, but the zipper did get caught in the fabric a few times during use. The shell repelled condensation, dirt and debris well.
