I'm wondering if anybody has experience using a One Planet bag + Quest quilt as a booster?
I'm planning to do my first few multiday walks this year, and am in the process of putting my kit together. For a bag I'm looking at the One Planet Sonder (either -5 or -8, TBD). I think this should do me fine for the near future, I'll be starting out with overnighters in Vic autumn/spring/summer. Part of the reason I am drawn to One Planet is the option to add a Quest quilt as a booster to their bags - https://oneplanet.au/wp-content/uploads/2020/11/ONE-PLANET-Instructions-Quest-Booster.pdf. I can imagine that I'm likely to be interested in extending my hiking ventures into the winter months and into colder climates, and the Sonder + Quilt seems like a good 4-seasons system.
Does anybody have any experience with this setup that they can speak to? My main concern is whether it will be too snug inside the bag once the quilt is inserted. I don't like to be too constricted which is why I'm not considering any mummy shaped bags, and hoping there is still plenty of wiggle room.
Cheers.
