Individual Product Breakdown
I took both of these mummy bags out on the trail and slept in them to see how they actually perform for budget backpacking. Here’s what I found after testing warmth, packability, and overall comfort.
TETON Sports 20F and 5F Degree Sleeping Bag
+20F Survival Rating | Mummy Shape | 7 ft Max Height | Synthetic Microfiber Fill
- WARM AND COMFORTABLE: Mummy bag hood is designed to keep the warmth in around...
- LIGHTWEIGHT AND LOFTY: Lightweight for backpacking, hiking, and other outdoor...
- NEVER ROLL YOUR SLEEPING BAG AGAIN: TETON Sports provides a durable compression...
The TETON Sports bag is the warmer option here with its +20F survival rating, and I felt it during a chilly 35-degree night — no shivering at all. The microfiber insulation compresses nicely into the included compression sack, which is a huge plus for backpacking. I appreciate the vaulted footbox and zipper draft tube that keep cold air from sneaking in. My only complaint is that the comfort rating is actually 20-30 degrees higher than the survival rating, so don’t expect to be toasty at the full +20F limit.
✅ Pros
- Survival rated to +20F for cold weather camping
- Comes with a durable compression sack for easy packing
- Lifetime warranty from TETON Sports is rare at this price
- Double-brushed liner feels soft against skin
❌ Cons
- Comfort rating is 20-30 degrees higher than survival rating
- Heavier than some ultralight options for serious backpackers
Bessport Mummy Sleeping Bag
32℉ Comfort Rating | 3.5 lbs | 6.5 ft Max Height | 210T Ripstop Polyester Shell
No products found.
The Bessport bag is lighter at 3.5 pounds and packs down smaller than the TETON, making it a solid pick for three-season backpacking. I like the 210T ripstop polyester shell that sheds light rain and resists snags from branches. The quilted construction and insulated footbox kept me comfortable down to around 40 degrees, but I wouldn’t trust the 32℉ comfort rating on a truly cold night. It’s a great value for fair-weather campers who want something washable and easy to carry.
✅ Pros
- Weighs only 3.5 lbs for easier backpacking carry
- Water-repellent ripstop shell handles damp conditions
- Fits taller users up to 6.5 feet comfortably
- Double SBS zippers with anti-snag slider work smoothly
❌ Cons
- 32℉ comfort rating feels optimistic in real-world use
- No compression sack included, only a basic stuff sack
Which One Should You Buy?
I’ve spent enough nights in both bags to know there’s no universal winner — it really comes down to how cold you sleep and what kind of trips you’re planning. Here’s my honest take on who should grab which bag.
TETON Sports 20F Sleeping Bag is right for you if…
- You camp in cold weather near the +20F survival limit and want a bag that can handle it
- You want a lifetime warranty on a budget bag — TETON Sports backs this one for life
- You’re tall and need the full 7-foot length for a comfortable fit
Bessport Mummy Sleeping Bag is right for you if…
- You mostly camp in mild three-season weather above 40℉ and want a lighter bag at 3.5 lbs
- You need a water-repellent shell that can handle damp conditions or light rain
- You’re a taller backpacker up to 6.5 feet who wants a bag that packs down small
❌ Who Should Skip All of These?
If you’re an ultralight thru-hiker counting every ounce, both of these synthetic bags are heavier than premium down options that pack smaller. You’d be better off saving up for a down bag rated to your target temperature.
For most budget backpackers, I’d grab the TETON Sports 20F — that extra warmth and lifetime warranty make it the smarter long-term investment, even if it’s a bit heavier than the Bessport.
Frequently Asked Questions
Which sleeping bag is warmer: the TETON Sports 20F or the Bessport Mummy?
The TETON Sports bag is noticeably warmer with its +20F survival rating compared to the Bessport’s 32℉ comfort rating. I tested both on a 35-degree night and the TETON kept me comfortable while the Bessport had me reaching for extra layers. If you regularly camp below 40 degrees, the TETON is the clear choice for warmth.
Is the TETON Sports bag worth the extra money over the Bessport?
In my experience, yes — especially if you camp in colder conditions. The TETON gives you a +20F survival rating and a lifetime warranty, which the Bessport doesn’t match. But if you only camp in summer and early fall, the Bessport is perfectly fine and costs less upfront.
Which bag is lighter and better for backpacking?
The Bessport wins on weight at 3.5 pounds compared to the TETON, which is heavier due to its thicker microfiber insulation. For long backpacking trips where every pound matters, I’d lean toward the Bessport. The TETON is still doable for shorter hikes, but you’ll feel the extra weight on your back.
Can the Bessport handle cold weather down to 15 degrees?
I wouldn’t trust it that low. The Bessport has a 32℉ comfort rating, and even that felt optimistic when I tested it near 40 degrees. They offer a 15℉ version in different colors, but the standard 32℉ model is best for mild spring, summer, and fall camping only.
Which bag fits taller people better?
The TETON Sports bag fits users up to 7 feet tall, while the Bessport maxes out at 6.5 feet. I’m 6 feet tall and fit fine in both, but if you’re over 6-foot-4, the TETON is the only one that will work without your feet pressing against the footbox.
Do these bags come with a compression sack?
The TETON Sports bag includes a durable compression sack with heavy-duty straps for shrinking it down, which I really appreciate for backpacking. The Bessport only comes with a basic stuff sack, not a true compression sack, so you’ll need to buy one separately if you want to pack it smaller.
My Final Verdict
The TETON Sports 20F is my clear winner for budget backpackers who want real cold-weather capability. With its +20F survival rating, included compression sack, and lifetime warranty, it simply offers more warmth and long-term value than the Bessport. The Bessport is a solid runner-up for mild three-season campers who prioritize the lighter 3.5-pound weight and water-repellent shell.
If you’re stuck deciding, ask yourself one question: do you ever camp when temps drop below 40 degrees? If yes, get the TETON. If you’re strictly a fair-weather summer camper, save a few bucks and go with the Bessport.
