Temperature rating not accurate

I bought the Trestles Elite 20 because of the packability and the COMFORT rating of -6.5C. I have yet to have a sleep sufficiently warm enough even around 4-5 celsius, which is the lowest I have used this bad. I am not a cold person in general, but with this bag I have to wear multiple sets of thermals, multiple socks, and I have even resorted to taking a hot water bottle to bed to try and stay warm. I have had to now return to using my Asolo and Coleman bags, which are surprisingly much more warm, and only slightly larger/heavier. I really wanted this bag to work but it doesn't perform as marketed, and I am really disappointed in this Marmot product.

A nice little eco sleeping bag

[This review was collected as part of a promotion.] The sleeping bag has been great for both backpacking and car camping. Held up (just) in below freezing temperatures and does well for warmer temperatures. Light, cozy, packs pretty small. Easily fits back in it's stuff sack. We like how the women's had a choice of zip side. Needed a synthetic sleeping bag as my partner is vegan and we're happy with the purchase :) reasonably priced too. Good size for us (160-175 cm), although a little snug across the bag

Cozy and warm - great purchase!

[This review was collected as part of a promotion.] OMG sooo warm, soft and fluffy. I was able to pack it down pretty small in a stuff sack. Every night while I was backpacking, I looked forward to getting into this sleeping bag.

Great Marmot quality for sure

[This review was collected as part of a promotion.] Great quality as usual! Love the build compared to cheaper sleeping bags I bought in the past.

Comfy and warm.

Kept me warm on some pretty cold nights in Paragonia. I'm exactly 165 cm and have wide hips - it fits me great. I found the strings on the hood a bit tricky the first time I tried to tighten the hood (was the middle of the night though and I was sleepy). Best feature I've discovered so far is that it's water repellent - my friend's dog peed on the sleeping bag. I rinsed the area out with a hose for half a minute and in no time the sleeping bag was dry and with no trace of dog-pee smell or anything.

Great bag but not as soft as the Trestles 15

I bought this for my wife and as a back-up bag for when I take friends camping. I got a long so it was basically the same size as the men’s regular. I have the men’s Trestles 15 regular and I will say while this one is more money and lighter weight, the cheaper, slightly heavier 15 is way more comfortable. You can tell this one just isn’t as soft and comfortable. Idk why, maybe it’s the eco material. Other than that, it’s an excellent bag.

Snug like a bug!

[This review was collected as part of a promotion.] Only taken out for 1 camping trip since I bought this, but it was the most comfy sleep I've had in years. The fact that it's eco friendlier than most options really helped made my choice, more then other technical features. I was afraid it might be to cold. Not at all. It packs up alright, on the bigger side. I'd say perfect for car camping, decent for hiking trips! And it's eco friendly. If there's any doubt, that should help right? Any little change you can make will help!

Pretty good

[This review was collected as part of a promotion.] Went on a couple of trips with this bag, packs down okay... and is warm enough if you use it in the right seasons...

Love it!

[This review was collected as part of a promotion.] Bought this sleeping bag for backpacking and love it. It’s not very heavy so it doesn’t weight my pack down. Haven’t tried it out yet in very cold weather but I’m excited to see if it keeps me warm!
