Big Agnes Anthracite 30 Synthetic Sleeping Bag

Jump to: Our Verdict / Features / Specifications

A warm and cosy synthetic bag that goes along way to reduce cold spots and drafts from entering the bag.

Big Agnes says: 

Our Anthracite 30° traditional mummy style sleeping bag is designed to be taken anywhere and provide rest after a long day outside. Stay cozy with Fireline™ Pro Eco recycled synthetic insulation and a roomier mummy shape than a traditional bag design. Lightweight enough to stuff in your pack for summer backpacking but comfortable enough for backyard campouts with the kids, this bag is so versatile and comfortable you’ll want to take it on every outing!

Our Verdict

You get inevitable trade-offs with synthetic bags, which will perform well in damp and humid conditions for a start, but also, you are getting a good, trail-ready bag at a very reasonable price. The Anthracite 30 is a fantastic 3-season bag for any outdoor activity here in the UK, where the weather may not always be very predictable. It’s not going to pack down as small as a down bag and will weigh more than a down bag; however, if you need a bag to perform in unpredictable circumstances, say, for example, you are doing the Pennine way in October, this could be the bag for you.

It’s a generous-sized bag with plenty of room to toss and turn without the bag feeling constrictive. The Anthracite has a nice well-fitting hood, an oversized interior anti-draft collar and an insulated tube along the hood, which all increase the bag’s warmth, and prevent cold air from entering the bag.
