When it comes to polyester mummy sleeping bags, there are some things you should know. Polyester sleeping bags are designed with durable materials, so they can tolerate long-term use without fraying or falling part. They are made with breathable material, allowing the temperature inside your bag to stay comfortable and balanced. They are naturally hypoallergenic, so they are ideal for those with allergy sensitivities. These sleeping bags dry quickly, so even in the wettest conditions, moisture will not soak the fabric. They weigh less than rectangular bags, so they are best when you need maximum warmth for minimal weight. However, they provide less space to move around, making them uncomfortable for sleepers who toss and turn. An advantage is that they are good for cold weather, so they are designed to hold in warmth and keep out drafts.
