What's inside an Alpkit sleeping bag?
Our down sleeping bags use high-loft ethically sourced duck and goose down. We also use hydrophobic down to keep you warmer for longer in damp conditions. Our lightweight synthetic sleeping bags use durable Thermolite® Ecomade insulation and PrimaLoft® Gold, the highest quality of synthetic insulation available. We make left-zip and right-zip sleeping bags and offer extra long sleeping bags for extra long humans.
All Alpkit sleeping bag fabrics are treated with a PFC-free water repellent.
Responsible Down Standard
We use only RDS certified down. The RDS is an independent standard that guarantees our down comes from birds that are free from live-plucking, force-feeding, or mistreatment.
DownTek™ hydrophobic down
DownTek™ PFC-free water repellent down stays dry for up to 13.5x longer than untreated down. This makes it stay lofted for longer, dry quicker and recover better from damp.
PrimaLoft® synthetic insulation
Lightweight and compressible PrimaLoft® synthetic insulation is hydrophobic and treated with a water repellent finish. This means it maintains its insulative properties even when damp.
