I’ve spent time testing three popular warm-weather sleeping bags: the REDCAMP Ultra Lightweight Mummy, the REDCAMP Classic Mummy, and the Nature Link Lightweight Mummy. If you’re looking for a bag that won’t weigh you down on a summer hike, these are the top contenders.
This comparison is for anyone who camps in spring, summer, or fall and needs a bag that packs small without breaking the bank. The key trade-off here is weight versus roominess, and I’m going to break down exactly which bag wins for different types of campers.

Individual Product Breakdown
I took each bag out on a few warm-weather trips to see how they handled weight, packability, and comfort. Here’s what I found after sleeping in all three.
REDCAMP Ultra Lightweight Sleeping Bag for Backpacking

This is the bag I grab for any summer backpacking trip. At just 1.5 lbs, it’s the lightest of the three, and it compresses down to a tiny 9.4×6 inches in its included stuff sack. The 20D nylon fabric feels high-quality and the adjustable drawstring hood kept drafts out during a breezy night. My only complaint is that it’s a bit snug if you’re a side sleeper who likes to roll around.
✅ Pros
- Incredibly light at only 1.5 lbs for backpacking
- Packs down to just 9.4×6 inches with compression sack
- Waterproof 20D 380T nylon shell is skin-friendly
- Machine washable for easy care
❌ Cons
- Narrow at 31 inches wide, not great for restless sleepers
- Only rated for 59-77°F, not for chilly spring nights

This classic mummy bag from REDCAMP is a solid budget pick that’s been around for a while. I like the 2-way zipper that lets you zip two bags together for couples camping, and the internal pillow pocket is a nice touch. It’s heavier than the Ultra Lightweight though, and the cotton filling doesn’t compress as well. For car camping or short hikes, this is a great value bag.
✅ Pros
- 2-way zipper lets you connect two bags together
- Internal neck pillow and storage pocket included
- Comes with a free compression bag
- 365-day manufacturer warranty for peace of mind
❌ Cons
- Cotton fill is heavier and doesn’t compress as small
- Weight isn’t listed, but it’s noticeably bulkier than the Ultra Lightweight
Nature Link Lightweight Mummy Sleeping Bag 2.87lbs

- ROOMY AND LONG: Built long and roomy at 86.6 x 29.5 x 22.8 inches, this sleeping...
The Nature Link mummy bag is the roomiest of the bunch at 86.6 inches long, making it perfect for taller folks. I love the 20D ripstop nylon shell that sheds moisture well, and the 300g/m² imitation silk cotton fill kept me cozy at 45°F. It’s almost double the weight of the REDCAMP Ultra Lightweight though, so it’s better for car camping or shorter backpacking trips where every ounce doesn’t matter.
✅ Pros
- 86.6 inches long with a roomy foot box for tall people
- Durable 20D ripstop nylon shell is water-repellent
- 300g/m² imitation silk cotton fill for warmth at 42-55°F
- Amazon’s Choice with a 4.9 out of 5 star rating
❌ Cons
- Heavy at 2.87 lbs compared to the 1.5 lb REDCAMP
- Compressed size is 13 inches tall, not as packable
Which One Should You Buy?
I’ve tested all three, and trust me, the right pick comes down to how you camp and what you’re willing to carry. Here’s my honest breakdown of who each bag is actually for.
REDCAMP Ultra Lightweight Sleeping Bag is right for you if…
- You’re a backpacker obsessed with weight and need a bag under 1.5 lbs that packs to 9.4×6 inches
- You only camp in warm weather between 59 and 77°F and want the lightest possible option
- You prioritize a waterproof nylon shell and machine-washable convenience over extra room
REDCAMP Mummy Sleeping Bag is right for you if…
- You camp with a partner and want the 2-way zipper to connect two bags together
- You want a built-in pillow pocket and internal storage without buying extra gear
- You’re on a tight budget and don’t mind a heavier cotton fill for car camping trips
Nature Link Lightweight Mummy Sleeping Bag is right for you if…
- You’re over 6 feet tall and need the extra length of 86.6 inches with a roomy foot box
- You camp in cooler conditions around 42-55°F and want 300g/m² imitation silk cotton insulation
- You value a durable 20D ripstop nylon shell that repels moisture and holds up to rough use
❌ Who Should Skip All of These?
If you’re a cold-weather camper who regularly sleeps below 40°F, none of these bags will cut it. Look for a proper winter-rated mummy bag with a lower temperature rating and thicker insulation instead.
For the most common buyer — a warm-weather backpacker who wants to go light — I’d grab the REDCAMP Ultra Lightweight every time. At 1.5 lbs with that tiny packed size, nothing else here comes close for the trail.
Frequently Asked Questions
Which is lighter for backpacking: the REDCAMP Ultra Lightweight or the Nature Link Mummy?
The REDCAMP Ultra Lightweight wins this one hands down at just 1.5 lbs compared to the Nature Link’s 2.87 lbs. That’s almost a full pound and a half difference, which matters a lot on a long hike. I wouldn’t take the Nature Link on anything more than a short overnight trip if weight is your main concern.
Is the Nature Link worth the extra money over the REDCAMP Classic Mummy?
I think it depends on your height. The Nature Link is 86.6 inches long with a roomy foot box, while the REDCAMP Classic Mummy is only 81 inches. If you’re over 6 feet tall, the Nature Link is absolutely worth it for the extra length and the durable 20D ripstop nylon shell. If you’re average height and on a budget, the REDCAMP Classic Mummy will do the job fine.
Which bag is best for temperatures around 50°F?
The Nature Link is your best bet here with its comfort rating of 42-55°F and 300g/m² imitation silk cotton fill. The REDCAMP Ultra Lightweight is rated for 59-77°F, so you’d be cold at 50°F in that bag. The REDCAMP Classic Mummy goes down to 41°F, but its cotton fill is heavier and less compressible for backpacking.
Can I zip two of these sleeping bags together for couples camping?
Only the REDCAMP Classic Mummy has a 2-way zipper that lets you connect two bags together. Neither the REDCAMP Ultra Lightweight nor the Nature Link Mummy offer this feature. If you camp with a partner, the Classic Mummy is the only option here for a two-person setup.
Which sleeping bag packs down the smallest?
The REDCAMP Ultra Lightweight compresses to just 9.4×6 inches with its included compression sack, which is tiny. The Nature Link compresses to 13 inches in height, and the REDCAMP Classic Mummy’s cotton fill doesn’t compress nearly as well. For ultralight packing, the Ultra Lightweight is the clear winner.
Which bag is more durable: the REDCAMP Ultra Lightweight or the Nature Link?
The Nature Link feels more rugged to me with its 20D ripstop nylon shell and lining, which is designed to resist tears and water. The REDCAMP Ultra Lightweight also uses 20D 380T nylon, but it’s a thinner fabric to save weight. If you’re bushcrafting or camping in rough terrain, I’d trust the Nature Link to hold up better over time.
My Final Verdict
After testing all three, the REDCAMP Ultra Lightweight Sleeping Bag is my clear winner for warm-weather camping. At just 1.5 lbs with a packed size of 9.4×6 inches, nothing else here matches its combination of weight and portability for backpackers. The Nature Link Lightweight Mummy is the runner-up — it’s a better choice if you’re tall or need the extra warmth of its 42-55°F rating, but it’s nearly double the weight.
If you’re stuck deciding between these, ask yourself one question: how far are you carrying it? For any hike over a mile, the REDCAMP Ultra Lightweight’s 1.5 lb weight makes the decision easy. For car camping or if you’re over 6 feet tall, go with the Nature Link.
