Which one should you get? 15 or 30? Disco/Rave Riff/Jam 15 vs 30 Disco/Rave 30 will provide equal warmth to Riff/Jam 30.īut. Warmth debate concluded: Disco/Rave 15 will provide equal warmth to Riff/Jam 15. Now let's see where our two (*cough* four) bags stand: There are also EN Upper Limit and EN Extreme, which I won't go into detail, so you can check Wikipedia for that matter. Similar to EN Comfort, the lower the EN Lower Limit, the warmer you'll feel inside the bag. There are other measurements such as EN Lower Limit - which shows the minimum temperature at which a 25 year old, 5'8" (1.73 m) & 160 lbs male can sleep for 8 hours in a curled position without waking up. It's based on women since they sleep colder than men.
EN Comfortįor example, EN Comfort shows the minimum temperature a 25 year old, 5'3" (1.6 m) & 130 lb (60 kg) female can sleep comfortably inside the bag.
EN RatingsĮN 13537 is the warmth standard for sleeping bags, and there are different EN ratings. Now let's see where Disco/Rave and Riff/Jam stand. Lower EN Rating always means more warmth! It basically takes into account ALL the factors that affect the warmth of a sleeping bag and rate them on a scale. It's a standard metric used for the warmth provided by a sleeping bag. Now when we get to the long answer - I don't know the math behind these calculations, but I do know something more useful: EN 13537. Disco/Rave is filled with more 650 FP down, whereas Riff/Jam is filled with less 800 FP down.Īs a result, Riff/Jam weighs substantially (2-4 oz - depending on the model you get) less and its packed size is smaller.īut what about their ultimate warmth? Does Jam/Rave's 20.5 oz 800 FP down provide more warmth than Disco/Rave's 22.5 oz 650 FP down? But it certainly will be A LOT HEAVIER since it requires more down!Īnd that, kids, is what causes the key difference between Disco/Rave and Riff/Jam products. The amount of down is also very important - which is called "fill weight".Ī product filled with 500 FP down can provide the warmth a product with 800 FP down does. Now when I said "for its weight" above, what I'm trying to say is that Fill Power is NOT the only thing that determines the ultimate warmth of a bag. Generally speaking, for sleeping bags, over 750 FP (to my knowledge, they go up to 900 FP) is considered top notch quality down (Riff/Jam) whereas 600-750 FP as "medium" quality (Disco/Rave).
