I’ve tested two popular budget-friendly sleeping bags side-by-side: the REDCAMP Mummy Sleeping Bag and the YANLIFY Lightweight Sleeping Bag. Both are designed for 3-season backpacking, but they take very different approaches to keeping you comfortable at night.
If you’re trying to decide between a classic mummy shape that hugs your body or a roomier rectangular design, this comparison is for you. I’ll break down the real differences so you can pick the right one for your next trip.

Individual Product Breakdown
I took both bags on overnight trips, checked the zippers, tested the packed size, and slept in them to see which one really delivers for backpackers.

The REDCAMP mummy bag is the warmer of the two, with a cotton fill rated down to 41°F that actually kept me cozy on a chilly spring night. I really like the built-in neck pillow and internal pocket for stashing my phone and wallet inside the bag. The 2-way zipper lets you zip two bags together if you’re camping with a partner, which is a nice touch. That said, the mummy shape is tighter than I’d like for side sleepers, and at a 4.2-star rating from just 40 reviews, it hasn’t been tested as widely as the competition.
✅ Pros
- Comfort rated to 41°F for colder spring and fall nights
- Comes with a free compression bag for packing down smaller
- Internal neck pillow and storage pocket add convenience
- 2-way zipper lets you connect two bags together
❌ Cons
- Mummy shape feels restrictive for side sleepers and tossers
- Cotton fill is heavier and bulkier than synthetic alternatives
- Only 40 customer reviews means less real-world feedback

The YANLIFY bag impressed me right out of the box with its spacious rectangular design that lets me stretch out fully — no more feeling trapped like in a mummy bag. It compresses down to just 39 x 26 x 10 cm and weighs only 1.35 kg, making it genuinely easy to strap to my pack for long hikes. The 190T tear-resistant polyester shell shed a light drizzle during my test, and the full-length two-way zipper opens flat to use as a blanket. My only knock is the comfort range of 50–68°F means it’s strictly a warm-weather bag, and the 3-month warranty is pretty short compared to the REDCAMP’s 365-day coverage.
✅ Pros
- Envelope design gives you tons of room to move around at night
- Weighs only 1.35 kg and packs down small for backpacking
- Water-repellent shell with tear-resistant 190T polyester fabric
- 4.8-star average from 23 reviews with over 700 sold in the past month
❌ Cons
- Comfort range of 50–68°F is not warm enough for cold nights
- Only a 3-month warranty compared to REDCAMP’s full year
- Rectangular shape loses more body heat than a mummy bag
Which One Should You Buy?
After testing both bags in real camping conditions, I can tell you there’s no single “best” choice — it all comes down to whether you prioritize warmth or space. Here’s who each bag works for.
REDCAMP Mummy Sleeping Bag is right for you if…
- You camp in cooler weather and need the 41°F comfort rating to stay warm in spring or fall
- You’re between 5.1 and 6.2 feet tall and don’t mind a snug mummy fit that traps heat
- You want a 365-day manufacturer warranty for extra peace of mind on your purchase
YANLIFY Lightweight Sleeping Bag is right for you if…
- You’re a side sleeper or toss and turn at night — the rectangular design gives you room to move
- You need a bag that compresses to just 39 x 26 x 10 cm and weighs only 1.35 kg for backpacking
- You camp mainly in warm weather between 50°F and 68°F and want a water-repellent shell
❌ Who Should Skip All of These?
If you’re planning winter camping or expect temperatures below 40°F, neither of these 3-season bags will keep you warm enough. You’ll want a 4-season expedition bag with a much lower temperature rating and thicker insulation.
For most casual backpackers and campers hitting the trail in spring, summer, or fall, I’d grab the YANLIFY for its roomy design and lighter pack weight — it’s the more versatile choice for the average buyer.
Frequently Asked Questions
Which is warmer, the REDCAMP mummy bag or the YANLIFY rectangular bag?
The REDCAMP is definitely warmer with its cotton fill rated to 41°F, while the YANLIFY’s comfort range starts at 50°F. I noticed the difference on a 45°F night — the REDCAMP kept me comfortable while I would have been chilly in the YANLIFY. If you camp in cooler spring or fall weather, the REDCAMP is the better choice for warmth.
Which bag is better for backpacking and carrying in a pack?
The YANLIFY wins for backpacking because it compresses to just 39 x 26 x 10 cm and weighs only 1.35 kg. The REDCAMP’s cotton fill makes it heavier and bulkier even with its included compression sack. For long hikes where every ounce counts, I’d take the YANLIFY every time.
Is the YANLIFY worth the extra money over the REDCAMP?
Both bags are priced very similarly, so it’s not really about cost — it’s about what you need. The YANLIFY gives you a higher 4.8-star rating, a roomier rectangular shape, and better portability. The REDCAMP offers a lower 41°F comfort rating and a much longer 365-day warranty. I’d say the YANLIFY is the better value for warm-weather campers who want space to move.
Can I zip two of these sleeping bags together for a couple?
The REDCAMP has a 2-way zipper that lets you connect two bags together, which is great for couples camping. The YANLIFY also has a full-length two-way zipper, but I’d double-check compatibility if you’re trying to zip two different brands together. For matching pairs, both bags can work, but the REDCAMP specifically advertises this feature.
Which bag is better for tall people over 6 feet?
The REDCAMP measures 81 inches long and fits people up to 6.2 feet in the green and wine colors, or up to 6.6 feet in the navy blue version. The YANLIFY measures (190+30)cm by 80cm, which is roughly 86 inches long. I found both bags accommodate taller folks, but the YANLIFY’s rectangular shape gives taller sleepers more room to stretch out their legs without hitting the foot box.
Which sleeping bag has a better warranty?
The REDCAMP blows the YANLIFY away here with its unconditional 365-day manufacturer warranty. The YANLIFY only offers a 3-month warranty, which is pretty short for a camping gear purchase. If warranty coverage matters to you, I’d lean toward the REDCAMP for that extra peace of mind.
My Final Verdict
The YANLIFY Lightweight Sleeping Bag is my clear overall winner for most backpackers. Its roomy rectangular design, lighter 1.35 kg weight, and compact packed size make it the more versatile choice for warm-weather camping trips. The REDCAMP Mummy Bag is the runner-up that I’d recommend specifically if you need the extra warmth of a 41°F comfort rating or prefer a snugger fit for cooler nights.
If you’re still on the fence, ask yourself one question: are you usually too warm or too cold when camping? For warm sleepers and summer hikers, the YANLIFY is the obvious pick. For cold sleepers who want a 365-day warranty, grab the REDCAMP.
