What is a bivvy bag and is it right for you?


Whether you’re a hiker seeking lightweight gear, a wild camper looking for simplicity, or after a reliable backup shelter, a bivvy bag keeps you dry, warm, and protected. This guide breaks down everything you need to know before buying a bivvy, plus our top picks to help you choose the best bivvy bag for your next adventure.

So, what is a bivvy bag?
A bivvy bag is a protective cover for your sleeping bag. It shields you from the elements while remaining breathable, so your sleeping bag doesn’t get damp. It’s camping in its simplest form, no tent required.

Bivvy bag pros & cons

Pros

Cons

Light & compact: bivvy bags tend to be a lot lighter and pack down much smaller than a tent.

Lack of privacy: if you’re out with others, you won’t have much privacy to get changed or have some alone time/

Fast & flexible set up: you only need a spot as large as your camping mat to pitch up, and getting set up is a lot quicker than pitching a tent.

Getting in & out: it can take some practice to master getting in and out of your bivvy

The views: you’re fully immersed in nature when using a bivvy. The sunset, stars and sunrise can be appreciated in all their glory

You’re vulnerable to weather: if the weather takes a turn, it can be a struggle to get everything inside your bivvy and get changed out of wet gear. Having a tarp can help with this.

Emergency backup: a bivvy is also great to have in your pack if you run into an emergency

It’s a small space: if you’re not a fan of small spaces, a bivvy may not be for you.


"For me, a bivvy bag is the only option when weight is at a premium. Even lightweight tents can add weight on a long walk into an alpine climb. A bivvy bag plus a small tarp is often easier to fit into a pack that also has to fit a rack and ropes. They provide just enough protection from the elements and sharp surfaces, keep your sleeping bag dry and unscathed, and give the bonus of an unhindered view of the starry sky." - Kerry, Digital Marketing Manager

Bivvy bag considerations

How do I choose the right bivvy bag?

Consider the intended use, features, and personal preferences when selecting a bivvy bag.

Key considerations: 


Intended use 

  • Emergency – go for minimal weight and tiny pack size 

  • Regular trips – choose comfort and ventilation 


Features to look for 

  • Hooped design – adds space and comfort at the head, this will add extra weight 

  • Bug mesh – vital in insect-heavy areas 

  • Material – waterproof and breathable fabrics 

  • Seam sealing – taped seams stop leaks 

  • Hood/closure – keeps rain out of your bag 


Personal preference 

  • Height – taller people need longer bags, most of the bivvies we stock range from 230-250cm 

  • Packability – Ultralight options pack down very small 

Final thoughts

Is a bivvy bag right for me?

Bivvy bags are a brilliant way to strip camping back to the essentials. They’re light, versatile, and ideal for nights when you want simplicity or need a backup shelter.

If you’re new to bivvying, start with a reliable waterproof model, then consider extras like a hooped design or bug mesh once you know your style of adventure. With the right bivvy, you’ll be ready for quick overnighters, emergency use, or a full lightweight setup in the wild.

I have always loved being outside and since I began working in the outdoor industry as a teenager I have been trying to find as many excuses to get out in the mountains as possible. Fortunately, working at Ellis Brigham has given me plenty of opportunity to escape the office and test some awesome gear, from trail running shoes to belay devices. Most of the time I can be found kicking around on my local fells in the Lakes, but I am lucky enough to have climbed and skied in some amazing places over the years, including Morocco, Norway and the Alps.
