Great quality underquilt, I bought the -5, so looking forward to testing it at cooler temperatures. The larger satchel is also a great way to store the quilt so as to not keep it compressed.
I've been hanging out for this underquilt for a while and currently have it setup under the patio. The warmth and wind buffer this quality product provides is outstanding. Looking forward to taking this out for real treks. The home storage bag is a great touch. As usual Alton Goods supplying the goods! It's even better that we can support a local business.
Chucking the sleeping mat and using this underquilt was a game changer and a weight saver for my set up. It is so much more comphortable and allows you to move around more and stay warm in your sleep. It feels like an electric blanket and protects your backside from the wind very well. If your a serious hammock camper it's definitely worth the investment.
