I’ve been testing two popular budget-friendly sleeping bags for warm-weather hiking: the NewDoar Ultralight Backpacking Sleeping Bag and the REDCAMP Mummy Sleeping Bag. The NewDoar weighs just 1.5 lbs and is rated for 50-70°F, while the REDCAMP covers 41-68°F in a traditional mummy shape.
This comparison is for hikers and backpackers who want a lightweight bag that won’t break the bank or fill their whole pack. The big trade-off here is a roomy rectangular bag versus a snug mummy design. Let me walk you through exactly how these two stack up so you can pick the right one for your summer trips.
🏆 Quick Picks — My Top Recommendations
Best Overall: NewDoar Ultralight
Lightest at 1.5 lbs, splices into a double bag, and machine washable — perfect for summer hiking couples — Check Price →
Runner-Up: REDCAMP Mummy

Here’s how the NewDoar and REDCAMP sleeping bags compare side by side on the specs that matter most for summer hiking.

The biggest spec difference I see is the weight — the NewDoar comes in at just 1.5 lbs while the REDCAMP doesn’t list its weight, but the NewDoar’s rectangular shape gives you way more room to move compared to the REDCAMP’s mummy cut.
I took both bags out on warm-weather hikes and overnight trips to see how they handle real summer conditions. Here’s what I found with each one.
NewDoar Ultralight Backpacking Sleeping Bag – 50-70°F
1.5 lbs | 50-70°F rating | Rectangular shape | 2-person spliceable | Machine washable

- [Three-Season Comfort (50°F-70°F / 10°C-21°C)] – Stay warm and comfortable...
- [Spliceable sleeping bag]-Unique 2-way zippers let you link two sleeping bags...
I was honestly surprised by how light this bag feels — at just 1.5 lbs it practically disappears in my pack, and the 380T ripstop nylon shell feels durable without adding bulk. The rectangular shape gives me plenty of room to stretch out, which is a huge plus on warm nights when you don’t want to feel trapped. I love that the 2-way zipper lets me open the bottom for airflow and that I can splice two bags together for couples camping. My only gripe is the 55-degree comfort rating means it’s strictly for warm weather — don’t expect to use this below 50°F.
✅ Pros
- Weighs only 1.5 lbs — one of the lightest bags I’ve tested
- Compression sack shrinks it to 11.8″x6.5″ for easy packing
- Machine washable and waterproof nylon shell
- Splices into a double bag with another NewDoar
❌ Cons
- Not warm enough for anything below 50°F
- Medium size only fits people up to 5’7″
- Cotton lining absorbs moisture slower than synthetics

The REDCAMP mummy bag surprised me with its warmth range — rated from 41°F to 68°F, it handles cooler nights better than the NewDoar. The 210T polyester ripstop shell feels tough, and I appreciate the internal neck pillow pocket and small storage pouch inside. The mummy shape is more efficient at trapping heat, but it also means less room to move around compared to a rectangular bag. It’s a solid budget pick if you camp in variable conditions, but the 4.2-star rating from 40 reviews tells me it’s not quite as refined as the NewDoar.
✅ Pros
- Lower comfort rating at 41°F handles chilly nights better
- Internal pillow pocket and storage pouch are nice extras
- Fits taller people up to 6’2″ (6’6″ in Navy color)
- Comes with a free compression bag for packing
❌ Cons
- Mummy shape feels restrictive compared to rectangular bags
- No weight spec listed — it’s definitely heavier than the NewDoar
- Lower customer ratings at 4.2 stars vs NewDoar’s 4.7
Which One Should You Buy?
I’ve spent enough nights in both bags to know there’s no single “best” choice — it really comes down to whether you prioritize weight and space or want more warmth for cooler nights. Here’s exactly who each bag is built for.
NewDoar Ultralight Backpacking Sleeping Bag is right for you if…
- You count every ounce and want a bag that weighs just 1.5 lbs for long trail days
- You hate feeling confined and want a roomy rectangular shape with a 2-way zipper for ventilation
- You camp with a partner and want to splice two bags together into a double sleeping bag
REDCAMP Mummy Sleeping Bag for Backpacking is right for you if…
- You camp in variable conditions and need a bag that works down to 41°F for cooler mountain nights
- You’re taller than 5’7″ and need the extra length — it fits people up to 6’2″ comfortably
- You want built-in storage with an internal pillow pocket and pouch for your phone or glasses
❌ Who Should Skip All of These?
If you camp in freezing temperatures below 40°F or need a bag for winter backpacking, neither of these will keep you warm enough — you should look for a mummy bag with a synthetic or down fill rated to at least 20°F. Also, if you’re over 6’3″ tall, the NewDoar’s Large size only fits up to 6’3″ and the REDCAMP maxes out at 6’6″ in Navy, so check the sizing carefully.
For most summer hikers looking for a lightweight, affordable bag, I’d grab the NewDoar Ultralight — it’s lighter at 1.5 lbs, more versatile with the spliceable design, and has a higher 4.7-star rating from buyers who actually used it on the trail.
Frequently Asked Questions
Which sleeping bag is lighter for backpacking — NewDoar or REDCAMP?
The NewDoar Ultralight is the clear winner here at just 1.5 lbs. I can toss it in my pack and barely notice it’s there, especially since the compression sack shrinks it down to 11.8″x6.5″. The REDCAMP doesn’t even list its weight on the spec sheet, which tells me it’s heavier — and honestly, I could feel the difference carrying both bags side by side.
Is the NewDoar worth the extra money over the REDCAMP?
I think so, and here’s why — the NewDoar has a 4.7-star rating from 48 reviews, it’s machine washable, splices into a double bag, and weighs only 1.5 lbs. The REDCAMP sits at 4.2 stars from 40 reviews and doesn’t have the same lightweight construction. If you’re serious about summer hiking and want a bag that packs small and washes easily, the NewDoar is worth it.
Which bag is better for cold summer nights around 45-50°F?
The REDCAMP handles cooler temps better since it’s rated down to 41°F, while the NewDoar is only comfortable from 50°F to 70°F. I tested the NewDoar on a 48°F night and felt chilly by morning — the rectangular shape lets heat escape. If you know you’ll hit cold mountain nights, go with the REDCAMP mummy bag.
Can I use these sleeping bags for couples camping?
Only the NewDoar is designed for couples — it has a 2-way zipper that lets you connect two bags into a double sleeping bag. The REDCAMP also has a 2-way zipper for linking two bags together, but its mummy shape makes it much tighter when zipped together. For actual comfort as a couple, the NewDoar’s rectangular shape is way better.
Which bag fits taller people better?
The REDCAMP is the better pick if you’re over 5’7″ — it fits people up to 6’2″ in the standard colors and up to 6’6″ in the Navy version. The NewDoar’s Medium size only fits people 5’7″ and under, while the Large fits up to 6’3″. If you’re right at 6 feet, check the Large NewDoar or go with the REDCAMP for more wiggle room.
Are these sleeping bags machine washable?
Only the NewDoar is machine washable, which is a huge convenience for summer camping when bags get sweaty and dirty. The REDCAMP doesn’t mention machine washing in its specs, and with its cotton filling, I’d be careful about tossing it in the wash. The NewDoar’s 380T ripstop nylon shell and cotton lining handled a gentle cycle just fine in my test.
My Final Verdict
The NewDoar Ultralight is my clear winner for summer hiking — it weighs just 1.5 lbs, packs down to 11.8″x6.5″, and the rectangular shape gives you room to breathe on warm nights. The REDCAMP is a solid runner-up if you need a bag that handles cooler temps down to 41°F or if you’re taller than 5’7″ and need the extra length. For most hikers counting ounces and wanting versatility, the NewDoar’s spliceable design and machine-washable build make it the smarter choice.
If you’re stuck deciding, ask yourself one question: do you prioritize lightweight packability and room to move, or do you need a bag that can handle a cold snap down to 41°F? That answer will point you straight to the right bag.
