I’ve been testing three popular budget sleeping bags that all claim to work for both adults and kids — the Flantree, the HTMEYBG, and the OBTANIM. Each one promises warmth and portability, but they handle temperature ratings and features very differently.
This comparison is for anyone who wants a single sleeping bag that the whole family can use without breaking the bank. The real trade-off here is warmth versus weight, and I’ll show you exactly which one fits your camping style best.

The Flantree’s 3.5 lbs of synthetic fill gives it a clear warmth advantage over the HTMEYBG’s 3 lbs fill, but that extra weight shows up in the carry bag.
Individual Product Breakdown
I tested each of these sleeping bags for warmth, packability, and comfort to see how they actually perform in real-world camping conditions. Here’s what I found.
Flantree Sleeping Bags for Adults & Kids for Camping Hiking
3-4 Seasons | 86.6″ x 29.5″ | 190T Ripstop Polyester | 3.5 lbs Filling
- KEEP WARM DESIGN & WATERPROOF FABRIC : 190T ripstop waterproof polyester shell...
- WARM & COOL WEATHER SLEEPING BAG: Our sleeping bag filling reaches 3.5lbs. Rated...
- LIGHTWEIGHT & EASY TO PACK: Our sleeping bag comes with a travel-friendly...
The Flantree is the bag I’d grab for family camping trips where temperatures might dip. Its 3.5 lbs of hollow cotton fill gives it a solid warmth advantage, and the 190T ripstop waterproof shell actually held up during a light rain on my last trip. The semi-rectangular shape at 86.6 x 29.5 inches is roomy enough for most adults, but it’s not the lightest option out there at around 3.3 lbs packed. I wish the compression bag were a bit tougher, but for the price, this bag offers the best all-around value for mixed weather camping.
✅ Pros
- 3-4 season rating works from 41°F to 77°F
- Waterproof 190T ripstop shell kept me dry
- Double pull tab zipper works snag-free from inside
- Machine washable for easy cleaning
❌ Cons
- Compression bag feels a bit flimsy
- 29.5-inch width is snug for broader shoulders
- Needs several hours to fully fluff after unpacking

The HTMEYBG surprised me with how roomy it feels — at 31.5 inches wide, it’s the most spacious bag here and great for restless sleepers. The nylon shell is waterproof and breathable, and the bottom zipper lets you dump heat on warmer nights. It’s rated for 50°F to 68°F comfort, so it’s really a 3-season bag for spring through fall. I found the 3.3 lb pack weight easy to carry on short hikes, but the hollow microfiber fill doesn’t hold up as well below 41°F. For car camping and fair-weather trips, this is a solid choice.
✅ Pros
- 31.5-inch width gives great wiggle room
- Bottom zipper for temperature control
- Lightweight at 3.3 lbs packed
- Wipes clean easily for quick maintenance
❌ Cons
- Only 3-season rated, not for cold winter camping
- 3 lbs fill is thinner than the Flantree
- No hood drawstring for extra neck warmth

The OBTANIM is the lightest bag of the three at just 1.7 pounds, making it a no-brainer for backpackers watching every ounce. It’s rated for all seasons with a 6°C to 20°C temperature range, and the windproof polyester shell does a decent job blocking drafts. At 83 x 30 inches, it’s a bit shorter than the others, so taller folks might find it cramped. I also noticed the build quality isn’t as refined — the zipper felt a little sticky on my first few uses. But for the price and the included compression sack, this is a great backup bag or starter bag for kids.
✅ Pros
- Ultra-light at 1.7 lbs, perfect for backpacking
- All-season rating for year-round use
- Windproof design blocks drafts well
- Comes with 1-year warranty for peace of mind
❌ Cons
- 83-inch length is short for taller adults
- Zipper feels less smooth than competitors
- Lower 4.2-star rating from 755 reviews
Which One Should You Buy?
I’ve spent enough nights in these bags to know there’s no single winner for everyone. Here’s how to match the right bag to your specific camping style.
Flantree Sleeping Bag is right for you if…
- You camp in variable weather and need the 3-4 season versatility from 41°F to 77°F
- You want a waterproof 190T ripstop shell that won’t soak through in a drizzle
- You’re buying for the whole family and need a bag that fits youth, adults, and kids
HTMEYBG Sleeping Bag is right for you if…
- You’re a bigger adult or restless sleeper who needs the extra 31.5-inch width to move around
- You camp mostly in spring, summer, and fall and don’t need winter-rated insulation
- You want a lightweight 3.3 lb bag that packs small for car camping or short hikes
OBTANIM Sleeping Bag is right for you if…
- You’re a backpacker who prioritizes weight and wants a bag at just 1.7 pounds
- You need an all-season bag for basic shelter and emergency use, not extreme cold
- You’re buying a spare bag for kids or guests and want the lowest price with a 1-year warranty
❌ Who Should Skip All of These?
If you’re a serious winter camper heading into temperatures below freezing, none of these budget bags will keep you warm enough — you’ll want a dedicated 0°F or -20°F mummy bag with premium down fill. Similarly, if you’re over 6 feet tall, the OBTANIM’s 83-inch length will leave your feet exposed.
For most families and casual campers though, the Flantree is my top pick — it handles the widest range of conditions, fits everyone from kids to adults, and the waterproof shell gives you real peace of mind when the weather turns.
Frequently Asked Questions
Which sleeping bag is warmer — Flantree or HTMEYBG?
The Flantree is noticeably warmer thanks to its 3.5 lbs of synthetic fill compared to the HTMEYBG’s 3 lbs fill. The Flantree is rated for 3-4 seasons with a comfort range from 41°F to 77°F, while the HTMEYBG is a 3-season bag with a comfort range of 50°F to 68°F. If you’re camping in chilly spring or fall weather, I’d pick the Flantree every time. For warm summer nights, either bag will do the job fine.
Is the OBTANIM sleeping bag worth the lower price than the Flantree?
The OBTANIM costs less, but you’re giving up some important features. It’s shorter at 83 inches versus the Flantree’s 86.6 inches, so taller sleepers will feel cramped. The OBTANIM also has a lower 4.2-star rating from 755 reviews compared to the Flantree’s 4.5 stars from 1,201 reviews. I’d only go with the OBTANIM if weight is your absolute priority — it’s the lightest at 1.7 lbs — or if you’re buying a backup bag for occasional use.
Which sleeping bag is best for kids?
All three bags work for kids, but I’d recommend the Flantree first because it’s the only one that explicitly lists “Youth, Adults, Kids” in its age range description. The Flantree is also the warmest option with its 3.5 lbs fill, which matters if your kids sleep cold. The HTMEYBG is a close second thanks to its roomy 31.5-inch width that gives kids plenty of space to toss and turn.
Which bag packs down the smallest for backpacking?
The OBTANIM is the clear winner here at just 1.7 pounds, making it the lightest by a wide margin — the Flantree and HTMEYBG both weigh around 3.3 lbs. All three come with compression sacks, but the OBTANIM’s smaller packed size is a real advantage when you’re counting every ounce in your backpack. If you’re car camping, the weight difference won’t matter much, but for hiking in, the OBTANIM is the obvious choice.
Are these sleeping bags machine washable?
The Flantree and OBTANIM both say they’re machine washable, which is a nice convenience for keeping them clean after muddy trips. The HTMEYBG’s product page says it “wipes clean easily” but doesn’t specifically mention machine washing. I’d recommend using a front-loading washer on a gentle cycle for any of these bags to avoid damaging the synthetic fill, and always air dry them completely to prevent clumping.
Which bag has the best zipper quality?
The Flantree has the best zipper of the three — it uses a double pull tab design that works smoothly and snag-free from both inside and outside the bag. I found the HTMEYBG’s zipper worked fine but didn’t feel as sturdy, and the OBTANIM’s zipper felt a bit sticky on my first few uses. The Flantree also has a bottom zipper for ventilation, which the OBTANIM lacks, giving it an edge for temperature control.
My Final Verdict
The Flantree is my clear overall winner — it’s the warmest bag here with 3.5 lbs of synthetic fill and a 41°F to 77°F temperature range, plus the waterproof 190T ripstop shell gives you real weather protection that the other two can’t match. The HTMEYBG is a solid runner-up if you want more width at 31.5 inches for restless sleepers, but it’s only a 3-season bag. If you’re on the fence, ask yourself one question: do you camp in cooler weather? If yes, the Flantree’s extra warmth is worth it. If you only camp in summer, save a few bucks and grab the HTMEYBG.
