The SWING 700, like the 500 and the 900, is a realistic bag for beginners, where the price question becomes a part of the equation. But only a part, as the main issues is: durability quality and safety.
Now if you need a sleeping bag, to sleep in and keep you warm, the famous Pyrenean duck 90/10 will do a better job than any standard 90/10 industrial goose on the market, at a lower price.
The key question about isolation quality is not in the race, but in the method of racing, and especially in the question of maturity of the animal, exactly as it is with the French Gray goose.
But the real beauty of the SWINGS is a super well balance between the sure volume on the body section and the sure volume on the leg section. You have the double comfort of a large general volume, with the same feeling of over space on the body and leg section.
So, in a SWING, you can let loose, and go to sleep without worries.
