The Spark II has the same streamlined, feather-weight design as the Spark I with additional proportional 850+ down fill to take you into cooler summer through fall temps.

Sea to Summit gives you everything you need for a trip out with the excellent compression sack, and everything you need to store it at home in the bigger storage sack. It's definitely pricey, but if you're looking to lighten your load (and, unfortunately your wallet), you son't be going wrong choosing this.
I purchased this primarily for a recent trip to hike the Inca Trail to Machu Picchu. Temperatures at night went to around freezing, but I didn't want to get the warmer Spark because it'd be too warm for spring/summer/fall applications, and I didn't feel that the cooler Spark would be warm enough for this hike. The bag and liner worked fantastically. I wore base layers at night along with the bag and liner, and for the most part, I was quite comfortable, if not too warm, which is a good problem to have, for me anyway.
I purchased this to get a nice down sleeping bag that was very light (I have limited space and weight when traveling). It excelled in this. After reading a number of reviews on down sleeping bags, I decided on this one both for its price and its size. One of the biggest criticisms I saw has to do with the 1/3 zipper, which does, admittedly, limit the versatility of this bag. Sea to Summit probably could have a full zipper and not add that much weight to the bag. Getting into the bag can be a little bit of a trick, but not that bad. Basically, I slip it on like I would a pair of pants when I'm in the tent. That works great. The bag does not have a neck baffle, so you could get drafts. For me, that wasn't that big of a problem. The compression sack that comes with the bag is great, but I have yet to compact it down as small as some of the pictures show. Smallest I can get it is probably 7-8" long.
Definitely recommend this bag, particularly if you're being size or weight conscious. It's expensive, but compared to other down bags, this is a steal.
