What could be better than sleeping out in the open making wishes on shooting stars, breathing in that crisp, fresh air and waking up to a beautiful sunrise.

The Hunka is compact at under 400 g; perfect for all adventurers from alpinists and big wall climbers to minimalist campers and expedition leaders.

For now, we will disregard the argument as to whether the Hunka is a bivvy, bivi or bivouac sack (it is a bivvy bag by the way) and focus on the fun you can have with it! If Mr Microadventure himself, Alastair Humphreys, hasn’t yet persuaded you of the wonders of the bivvy bag lifestyle, allow us to tell you a few of the best bivvy qualities. A bivvy bag will keep your sleeping bag safe from the elements; no more soggy down! And no more anxious nights laid awake worrying if your down bag is going to survive to the morning in a dripping snowhole. A bivvy bag is your answer! Access to the bag is through a simple drawcord closure system at the head of the bag. This can be cinched down tight to keep all but the worst of the weather out. You will be protected by the waterproof and windproof fabric, it is extremely breathable to minimise condensation build up in your sleeping bag and in clear skies the opening can left open to further help with this. With an integrated stuffsack located on the foot section of the bag, it can be quickly packed away.

Best Bivvy out there

I've used this while cycling John O'Groats to Lands End. It's super light weight and keeps your sleeping bag dry as can be. Cannot recommend highly enough. I'm 5ft 7in and the bag fits comfortably. Any taller than 6ft then the XL is for you.

Great Budget Bivvy Bag

I bought this never having used or owned a bivvy bag before nor having heard of AlpKit. Great price and excellent customer service. Bivvy bag itself is a good size, well waterproofed and very light. Dries pretty quickly too. I have no complaints.

Solo Hiker
XL for Larger person

I have the XL version and I have recently used this over night in the Brecon Beacons. I am 6FT 1in and I am able to get my Airo 180 mattress, four season down sleeping bag, Heiko jacket, blow up pillow and moblile phone inside with some more room left.
The temperature was below freezing and the only condensation I had was near to where I was breathing.
I am very pleased with this bivvi bag.

Hunka Bivvy.

The Hunka is an excellent bivvy bag at an equally amazing price mark. I have used it on a number of trips around the UK over the last 12 months or so and have had no problems with it so far.
It is lightweight and has a small pack size, perfect for any adventure.
For use in the UK I don't see the need to use anything more technical - perfect those who want to get out and have their own micro-adventures!


This review is about 3 years late. That's how long I've been using a Hunka bivvy bag to sleep in the unlikeliest of places. It's light, it's tough, and it's absolutely waterproof - as I discovered in a 3am rain-storm on the Yorkshire coast one horrible, horrible day. (It kept me perfectly snug & dry during 6 hours of hammering rain - and as soon as I climbed out of it, instantly soaked.) This is my first bivvy bag, and at this rate, it may be my last (which I mean in the very best possible way.)

Spot On!

So since i can remember, I've always wanted to sleep out in the hills under the open sky, with the one problem being I live in one of the wettest counties in the country. I finally managed to convince my other half that bivvi bags were a good idea, although forking out £100+ each for a most bags seemed crazy. I've spent a night in a survival bag at a scout camp and i can tell you now, it was miserable.

Since i discovered alpkit last year, i have had my heart set on a couple of Hunkas, and i finally got them. As the weather was reasonable (light drizzle through the day, but a dry night forecast) we set off into the hills for our own little micro adventure. Setup was a doddle, and took all of 30 seconds, then it was brew on, bags on, and a beautiful sunset across the valley. The temperature dropped to about 4 degrees through the night according to the forecast, but i kept snug as a bug all night! And there is no better way to wake up than the sweet smell of spring and a Herdwick staring down at you from the fell!

The bags were great, keeping us both warm and dry. My down bag had plenty of space to loft, and despite the wind which got up through the night, i was plenty warm enough! I woke pleasantly surprised to find that my sleeping bag was not just a mass of wet feathers, but was still pretty dry and warm, so breathability is all right! As for waterproofing, we slept on a fairly damp patch and neither of us got wet from below. The ties round the hood were plenty adequate to pull right up round your head to keep warm and dry, so that's also a winner!

We had a fantastic night, and will be heading back out as soon as we get chance! My only negative comment is minor and more of a suggestion for a new design. The bottom of the bivvi bags have a mesh pocket to act as a stuff sack. I couldn't for the life of me get this to work properly, and was just left with a lumpy awkward mass to pack away. Instead, i rolled my bag from foot to head. Perhaps a small velcro strap could be added to the hood to hold it all once rolled? This is a much easier shape to pack in my opinion.

In summary, this is a great product for a great price. I cannot fault Alpkit, and will be adding to my collection shortly! Thanks!

Hunka dory

Fantastic bit of kit. Me and my three mates have had hunkas for three years or so, been on dozens of bivvy trips and they are as new and have never let us down. I did a lot of research before buying and don't think there's a better quality or better designed bag on the market, even spending silly money.

Fantastic bivvy bag

I ordered Hunka couple days ago, I am really impressed how quick parcel came to Poland. Last night finally I used bivvy bag on short bike trip near one of my favorite lakes just out of Gdansk city. It was pleasant misty night with around 8 Celcius. It worked great with my new down sleeping bag, so far no condensation even when it get warm at morning. Kelp colour is fantastic and also design is perfect. Well done.

Just perfect

I ordered the Hunka 400g for an 8 day hike, sleeping out under a tarp that would see me all kinds of weather.
It was absolutely brilliant, my sleeping bag was never wet from condensation and my sleeping bag a -3 bag had masses of loft space.
The lady at Alpkit was spot on, it did not let me down in any way. I only wished I had ordered one ages ago.

J MacBikey

Used for the first time at the w'end in ~14ºC with a one season sleeping bag, on the N Y Moors. It was a dry evening but I was at least expecting *some* condensation build up on the inside but there was nothing. Near enough dry on the inside and nothing on my sleeping bag. Very surprised and impressed.

Quality and finish seems to be usual Alpkit high standard but time and further use will test that. Size and weight of the compressed/stuffed bag is also a bonus for those trying to keep weight/bulk down (I was bikepacking)

Cracking bivvy!

Had mine nearly a year now, never failed me even in some sketchy conditions, couldn't recommend it more!


Super light, easy to pack and unpack, good quality and well priced.

A good entry level bivvi bag

As stated in the title, the Hunka is a great entry level bag. With that being said it's a bit hard to get into. A simple half length waterproof zipper would be something I think most people would happily pay extra for. Also purchase a head-net! It's moderately lightweight, sometimes I simply use it to keep condensation off my down quilt. Thinking about adding a few mods to it myself. I do think this is a great buy for someone starting out in the bivvi option. If you want to keep your gear inside the bivvi with you, I'd opt for the XL option.



Faraway Visions review Hunka

Faraway Visions review the Hunka

It packs up nice and small in its very own little integrated home, which is wonderful if you’re an untidy camper. No need to go looking for some cute little drawstring sack when you’re up before dawn freezing your nuts off.

You can do just about everything with [the MytiMug] - cook in it, eat out of it and drink from it. Now that is space saving!

Another suberb value offering from Alpkit... We used [the Numo] down to 0°C to great effect.

Andy McCandlish

For the money [the Hunka] really can't be beaten ... The small pack size and built-in stuff sack are a very welcome bonus.
