Sleep Better, Go Further, Stay Cooler
In warmer climates or during the hot summer months, a full winter bag is overkill. You’ll end up overheated and sweaty, which can reduce the insulation performance of your warmer (and more expensive) sleeping bag over time. That’s where an Ultralight Summer Sleeping Bag comes in handy. It keeps you comfortable without trapping too much heat, offering the perfect balance of insulation and breathability so you stay cool, comfortable and dry all night long.
Only Carry the Insulation You Need
Weighing just 512g, the Summer Sleeping Bag is significantly lighter and more compact than the Sleeping Bags in our range. That’s a huge advantage for adventurers who are looking to go as light as possible. Although intended for use in warm weather or camping in heated huts, by pairing your Ultralight Summer Sleeping Bag with a warm liner, wearing more layers, or using it with an insulated sleeping mat, you can bump up the warmth to handle slightly cooler nights if needed.
Built for Warm, Humid Environments
Our Ultralight Summer Sleeping Bag is built to perform in warm, humid conditions where untreated down would usually fail. It’s filled with 850FP DownTek™ PFC-Free Water Repellent Down that stays dry for over 10 times longer than untreated down. On top of that, the ripstop nylon shell is treated with a PFC-free C0 DWR coating that is highly water resistant, making the Ultralight Summer Sleeping Bag the ideal choice for warm, humid climates with frequent rainfall.
Ultralight Comfort for Any Sleeping Position
The Ultralight Summer Sleeping Bag is designed to provide efficient warmth and comfort for any sleeping position. Its tapered mummy cut is slightly wider than standard, allowing you more room to spread out and get comfy on warm nights, while the square footbox ensures your feet can rest in a natural position without feeling cramped. If you’re feeling the chill, the hoodless opening can be cinched in a bit tighter for improved heat retention, giving you the flexibility to fine-tune warmth and ventilation as the conditions change.

I recently purchased the lightweight sleeping bag and am super happy with it. It's lightweight and will be perfect for my upcoming Camino in September. I would also like to say how great the service was at Alton. I messaged them with a question and they had responded within a few hours. I purchased the bag 2 days ago, and it was delivered this morning. I can't wait to use the bag, but am super impressed with the quality and design of the bag. Thank you
I recently purchased the lightweight sleeping bag and I am thoroughly impressed with the product. Firstly, the packaging immediately stood out. It was clear that someone at the other end truly cares about the customer experience. The attention to detail in the packaging made a great first impression. As for the sleeping bag itself, the quality is first class. The materials used feel premium, and the craftsmanship is evident. It is extremely comfortable to sleep in and performed admirably in cooler conditions, keeping me warm in temperatures as low as 6°C. One of the standout features is the included storage sack. This is a fantastic idea as it allows the bag to remain light and fluffy. The travel bag makes packing and transporting the sleeping bag incredibly convenient. The bag is very light and packs down to a remarkably small size, making it perfect for any adventure. Overall, I am thrilled with this purchase and can't wait to put it to the test next year when we walk the Camino de Santiago. Highly recommend this sleeping bag for anyone in need of a reliable and comfortable lightweight option!
Tried out the ultralight weight sleeping bag on the weekend. Temps were down to about 12degrees at Binna Burra and it was warm and comfortable. The bag compresses really well and takes no room in my pack. Great product for Qld winter and summer conditions
Super comfortable and warm, and really light weight and compact! Would 100% recommended.
Used this bag on a 5 degree night, with a bivvy bag and Alton sleeping mat, I was toasty as, the bag performed really well. Given I was fastpacking, the really light weight of the bag was especially useful too. Thanks Alton!
Good product, but overpriced. They did mention you have to pay customs when I ordered. Feels like a scam
Comfy.. super light.. good value.. So far so good
Tiny bag, almost no weight, with descent warmth. Paired with a good mat and a liner and I've been fine down to single digit °C, and easily opens up like a quilt when it gets warm. Pretty perfect for most of the year in Australia.
not sure how to wash it???
Ideal for my needs, very light and very compact. I have found that all of the Alton products that I have purchased to be well made quality goods.
Great sleeping bag, very light, very compact, very comfortable. Would 100% recommend. Just more great gear from Alton goods.
Bought 2 - one for me, 1 for son….light, easy to manage and super comfortable….
Nice and light and it feels as good as the other sleeping bags they have to the quality. Perfect for summer as you do not want a sleeping bag too hot. Noticed around 2-4am at night when the sleeping bag works well on a hot day as temperatures drop to that 10-15 degrees. Zipper sometimes need to be carful zipping up otherwise can get caught on the material and could rip it. Sometimes a feather comes out Over all epic sleep by bag and would not get anything else. Love there -5 to -10 sleeping bags like sleeping on cloud 9
Perfect combination! Used the Alton bugnet and the summer sleeping bag, and enjoyed a few nights on boat up at cooloola... perfect warmth, and mozzie free! Thanks, Alton!
Used it up Maldon a couple of weeks back, was a perfect warm weather sleeping bag
