Individual Product Breakdown
I took each bag out on a few trips and paid close attention to weight, packed size, warmth, and how comfortable they felt after a long day of hiking.
REDCAMP Ultra Lightweight Sleeping Bag for Backpacking
1.5 lbs | 59-77°F rating | 87″ x 31″ | 20D 380T nylon shell

- Ultralight & Portable: Weighing just 1.5lbs/700g, this ultralight sleeping bag...
- Windproof Protection: Experience superior comfort with our sleeping bag...
This is the lightest bag I tested at just 1.5 lbs, and it compresses down to 9.4 x 6 inches, which is tiny. The 20D nylon fabric feels quality and the 59°F to 77°F temperature range makes it perfect for warm-weather backpacking trips. My only complaint is that it’s a mummy shape with 31 inches of width, so it’s snug — not ideal if you move around a lot at night.
✅ Pros
- Only 1.5 lbs — incredibly light for backpacking
- Packs down to 9.4 x 6 inches with compression sack
- Waterproof 20D 380T nylon shell is skin-friendly
- Machine washable for easy care
❌ Cons
- Only rated for 59°F to 77°F — not for cold nights
- Mummy shape is snug at 31 inches wide
Nature Link Lightweight Mummy Sleeping Bag 2.87lbs
2.87 lbs | 42-55°F rating | 86.6″ x 29.5″ | 20D ripstop nylon shell

- DURABLE NYLON SHELL AND LINING: This sleeping bag is made of 20D ripstop nylon...
- ROOMY AND LONG: Built long and roomy at 86.6 x 29.5 x 22.8 inches, this sleeping...
The Nature Link strikes a really nice balance between weight and warmth at 2.87 lbs with a 42°F to 55°F temperature range. The 20D ripstop nylon shell feels durable and the 86.6-inch length gives tall folks plenty of room. I wish it packed down a bit smaller than 13 inches in height, but for 3-season camping it’s a solid pick.
✅ Pros
- 2.87 lbs is a great weight-to-warmth ratio
- 42°F lower limit works well for 3-season camping
- Durable 20D ripstop nylon shell is water-repellent
- Roomy foot box adds insulation for cold toes
❌ Cons
- Compressed size is 13 inches — not as packable as REDCAMP
- 29.5-inch width is still pretty snug for bigger sleepers
Northroad Mummy Sleeping Bag 14-59 ℉
4 lbs | 14-59°F rating | 31.4″ shoulder width | 210T plaid shell
- 𝐏𝐋𝐄𝐍𝐓𝐘 𝐎𝐅 𝐑𝐎𝐎𝐌: This cold weather sleeping...

The Northroad is the warmest bag here with a 14°F lower limit, so it’s your go-to for chilly spring or fall camping. It weighs 4 lbs which is heavy for backpacking, but the 31.4-inch shoulder width gives you more room to move than the other mummy bags. The hollow cotton fill keeps you toasty, though it doesn’t pack down as small as the synthetic options.
✅ Pros
- 14°F lower limit is the warmest of the three
- 31.4-inch shoulder width offers more wiggle room
- Water-repellent shell with double SBS zippers
- Accessory pockets are handy for small gear
❌ Cons
- 4 lbs is heavy — not ideal for long backpacking trips
- Compressed size of 10.23″ x 15.74″ takes up more space
- Cotton fill doesn’t compress as well as synthetic
Which One Should You Buy?
I know picking a sleeping bag can feel overwhelming, but the right choice really comes down to how you camp and what you’re willing to carry. Let me break it down by who each bag is built for.
REDCAMP Ultra Lightweight Sleeping Bag is right for you if…
- You’re an ultralight backpacker who needs to shave every ounce — this bag weighs just 1.5 lbs.
- You only camp in warm weather (59°F to 77°F) and want the smallest packed size at 9.4 x 6 inches.
- You want a machine-washable bag that’s easy to care for after a muddy trip.
Nature Link Lightweight Mummy Sleeping Bag is right for you if…
- You do 3-season camping and need a bag that handles cooler nights down to 42°F.
- You’re tall and want a bag that’s 86.6 inches long with a roomy foot box.
- You want a durable 20D ripstop nylon shell that can handle brush and rocks.
Northroad Mummy Sleeping Bag is right for you if…
- You camp in cold weather and need a bag with a 14°F lower temperature limit.
- You want extra elbow room with a 31.4-inch shoulder width and accessory pockets.
- You’re car camping or doing short hikes where 4 lbs isn’t a dealbreaker.
❌ Who Should Skip All of These?
If you’re a side sleeper who tosses and turns all night, these mummy-style bags will feel too restrictive — you’d be happier with an envelope or rectangular bag that gives you more space. Also, if you regularly camp in temperatures below 14°F, you’ll want a proper winter bag with higher insulation ratings.
For most backpackers hitting the trail in spring, summer, or fall, the REDCAMP Ultra Lightweight is my top pick — it’s hard to beat 1.5 lbs and a tiny packed size for the price. If you need a bit more warmth for 3-season trips, grab the Nature Link instead.
Frequently Asked Questions
Which is lighter: the REDCAMP or the Nature Link?
The REDCAMP Ultra Lightweight is significantly lighter at just 1.5 lbs compared to the Nature Link at 2.87 lbs. That’s almost a full pound and a half difference, which matters a lot on longer backpacking trips. If weight is your top priority, the REDCAMP is the clear winner here.
Is the Northroad worth the extra weight for colder camping?
Yes, if you actually camp in cold weather. The Northroad has a 14°F lower limit while the REDCAMP only goes down to 59°F and the Nature Link stops at 42°F. That extra warmth comes at a cost though — the Northroad weighs 4 lbs, which is over double the REDCAMP. For warm-weather trips, you’re just carrying dead weight.
Which bag packs down the smallest for backpacking?
The REDCAMP compresses down to just 9.4 x 6 inches with its included compression sack, which is tiny. The Nature Link compresses to about 13 inches in height, and the Northroad’s packed size is 10.23 x 15.74 inches. If space in your pack is tight, the REDCAMP is the most compact option by far.
Can the Nature Link handle colder nights than the REDCAMP?
Absolutely. The Nature Link is rated for 42°F to 55°F, while the REDCAMP is only comfortable from 59°F to 77°F. That means the Nature Link can handle a chilly spring or fall night that would leave you shivering in the REDCAMP. For 3-season versatility, the Nature Link is the better choice.
Which bag is roomier for someone who moves around at night?
The Northroad has the most shoulder room at 31.4 inches wide, compared to the REDCAMP at 31 inches and the Nature Link at 29.5 inches. But honestly, all three are mummy-style bags that fit snugly. If you really need space to move, you’d want an envelope-style bag instead.
Is the REDCAMP durable enough for regular backpacking trips?
I think so. The REDCAMP uses a 20D 380T nylon shell that’s waterproof and skin-friendly, and it’s machine washable for easy care. The 20D fabric is on the lighter side so it won’t hold up to heavy abuse, but for normal hiking and camping it’s plenty durable. Just don’t drag it over sharp rocks.
My Final Verdict
After testing all three, the REDCAMP Ultra Lightweight is my clear winner for most backpackers — it weighs just 1.5 lbs and packs down to 9.4 x 6 inches, which is unbeatable for long hikes in warm weather. The Nature Link takes the runner-up spot for anyone who needs a bit more warmth down to 42°F without going overboard on weight at 2.87 lbs.
If you’re still on the fence, ask yourself one question: are you hiking miles to your campsite or driving there? For hiking, go REDCAMP. For car camping or cold nights, go Northroad. Don’t overthink it.
