I'm looking for a men's long, left-zip, down sleeping bag rated for around 15 degrees. I would like one that is compatible with my wife's sleeping bag which has a YKK #8 zipper, but zipper gauge is rarely listed on the specs. Can you point me to some that meet these conditions?
@se thanks for reaching out with this question - it's a tricky one! As you've noticed, it is difficult to identify the specific gauge on a zipper online - this will be difficult for us as well here in the community. So, we will need a little more information before we can make any helpful recommendations:
We'll look forward to hearing back from you with that additional information so we can provide a few specific recommendations. With that said, we may not be able to guarantee a compatible zipper.
Phew. I forgot to reply, sorry.
She has an older Big Agnes bag although I tried buying a new Big Agnes bag and found the zipper was different. I'm looking for an extra long down bag that's reasonably lightweight and packable for backpacking and bike touring.
