Robby & Everyone, I'm newer to forums and appreciate all the experience and knowledge you guys provide! I live in SW MT and purchased the SG Chilkoot 15 last year based off of your review.
Everyone probably knows this already but I found the following interesting, the SG 15 bag's comfort rating is 21 with a limit rating of 8. So I guess they decided to call it a "15 degree bag" because it it in the middle and sounds good? Another interesting tidbit is that the Chilkoot 0 degree bag's comfort rating is 14 and the limit is 0 and they call it a "0 degree bag" instead of a "7 degree bag", maybe because it also sounds better?
I'm not trying to talk poorly about SG and I really like my SG bag, it's just that there seems to be a slight variance in the way the bags were named, therefore, I think there is a "better bang for your buck" with the 15 degree version; as far as ratings and cost are concerned as well as weight to warmth ratio as noticed in the photos. This appears to make the SG 15 a slightly higher rated bag, at least by the numbers but not real world tested, than the current bags being reviewed and may be a "sleeper" of a deal in the current market.
weight/temperature ratio
- Chilkoot 15 (35oz ) = 2.3oz per 1 degree
- Chilkoot 0 (42oz) = 6.0oz per 1 degree (at a 7 degree mean rating to match the 15 bag temp rating)
**Another thing I noticed is that the 0 degree bag weighs 7oz more than the 15 degree bag so that is a 1oz to 1.14 degree ratio between the two bags (15 degrees and 7 degrees), or, the 7oz weight gain provides 8 degrees of warmth.**
I look forward to the rest of your testing! Thanks for letting me know what I'm missing or misunderstanding about what I've read and stated.
