The TETON Sports ALTOS Ultralight Mummy Sleeping Bag is ready for your next adventure. Roomy for a mummy bag and filled with your choice of sustainable synthetic fill or premium MTN-DRY hydrophobic white duck down. Both varieties are highly compressible, dry out quickly, and are lightweight but still have a thick loft to capture warm air and provide exceptional comfort.
Its three-piece hood contours to your face and keeps ears and head tucked in and warm. A shoulder draft tube also allows you to cinch the sleeping bag around your shoulders to prevent cold air from seeping in on those really cold nights.
The ALTOS unzips from the top and bottom with both interior and exterior zipper pulls making it easy to get in and out of. The zippers are fully taped with an anti-snag design and a full-length zipper draft tube. The shell is made from a sleek 20D micro ripstop and the liner is a cozy 20D nylon which are both durable yet lightweight. The hang loops on the exterior of the sleeping bag allow for easy hanging storage when not in use. The included heavy-duty compression sack makes pack-away quick and transport easy.

The Kelty seems to have a thicker and perhaps tougher shell (inside and out). (This could be more perception than actual I'm not sure.) The Kelty looks pretty good with its' multi color design. The Kelty didn't leak any down that I noticed. Those are the main pluses that I observed with the Kelty.
The Teton Sports bag is longer and roomier (wider) than the Kelty, and I don't feel at all cramped in it. The Kelty is a little short and tight by comparison, at least the regular size bag is.
The Teton Sports interior has a much softer and more comfortable feel to the skin than the Kelty.
The cinching system and hood of the Teton Sports is superior to the Kelty. It does a much better job of keeping you warm when temps drop.
The Teton Sports has a handy zipper pocket inside which is great for keeping my glasses (or cell phone, etc.). I couldn't find a pocket on the Kelty.
I found the zipper on the Teton Sports to be easier to use with its double zipper pull, and seems to be easier to zip without catching than the Kelty. I kept losing the Kelty zipper because it only has one pull, which wants to go outside where its harder to get a hold of, especially in the middle of the night.
The Teton Sports was warmer than the Kelty. I slept in the Teton down to about 28° and only got a little cool at times, but some readjusting helped. The Kelty had notable cold spots. I fluffed up both bags real good before entering them. The Teton Sports fluffs up bigger (better loft).
The Teton Sports comes with a compression bag as opposed to a stuff sack, which for me is only a minor detail, but some might find that important.
Both bags have their respective versions of "dry down", which is essential to me. I've had down bags to get wet, and they just never seem as lofty afterwards. The dry down seems to solve that problem.
I did notice some "ducky" odor with both bags, but the Kelty was stronger. Neither were intolerable to me, but the less the smell the better.
The only real negative with the Teton Sports is that I noticed some pieces of down floating around during use. I didn't notice any with the Kelty. I've used the Teton Sports bag twice now and the first time was worse than the second. I don't guess the very small amount of down lost would ever amount to anything in terms of warmth value.
If the Teton Sports bag holds up over time it will prove to be a great bag for the price.
For what it is worth, I have no particular brand loyalty, and received nothing in return for this review. If my experience with this bag should change I will update at that time.
-The fabric isn't super plasticy, it feels better on bare skin than any of my other bags
-It packs down smaller than they suggest (I got it to 11 X 8.5 X 8.5 without a struggle, which isn't huge but gives a fair bit more room if you're backpacking)
-I love that it has a little zip pocket inside, I use it to keep the battery life on longer trips [without my phone or goal zero sliding around my bag, the body heat helps]
-I haven't been through a rainstorm with it yet but I threw a bunch of water on it, it's definitely water resistant
-I haven't found anything significant yet. are there bags that pack smaller? yes. lighter? yes. but honestly bang for your buck this is an amazing bag
UPDATE: I recently acquired the Altos 20+ bag and took that out for a week long trek along the Highline Trail of the High Uintas last week. Temperatures got down into the mid 30's a couple nights, causing us to wake up to frost all over our camp. I paired the Altos 20+ with the Altos insulated air pad, also from Teton Sports, and I was comfortably warm every single night. I did not even have to zip up the bag the whole way or cinch it up at all, so I have no doubts that the Altos 20+ could hold up just fine in temperatures down in the 20's with it zipped up and the hood cinched down. This bag is supposed to be EN rated down to 20, meaning it really does have a comfort rating (not a survival rating) down to 20 degree, and I think this bag really delivers on that. I had no major problems with zipper snags. As with all bags, you just have to be careful and gentle with it to avoid the snags.
Not only is the 20+ bag nice and warm with great loft, but it also is very light and compresses down very well. Without the stuff sack, it is a little less than 2.5 lbs. Even with the stuff sack, it all came out to be only 2.45 lbs on my scale. I usually don't take stuff sacks, but with this trip, I did because it was essential that I compress the bag down as much as possible to free up space in my pack for all the food and other gear I needed for the week long trek.
One last thing to note is that I had no problems with down leaking. I saw no more than 2 to 3 stray feathers that escaped the whole trip. My other hiking buddy who had a North Face down bag said he was waking up with quite a few feathers all over him every morning.
Disclosure: I received this bag for an honest and thorough review.
