TETON Sports Leef Mummy Sleeping Bag - Lightweight Sleeping Bag for Backpacking, Camping, and Hiking - Cold-Weather Sleeping Bag - Camping Accessory with Drawstring Compression Sack

I recently camped in -14C with wind chill I climbed in with a base, mid and top layer on, plus a toque and I was uncomfortable all night. I was quite comfortable when it was only -5C

Es un buen saco de dormir, por el precio lo vale. Lo único medio engañoso es que la temperatura que te dice es la límite. En realidad la temperatura confort para el de 0f es 30f

Lo compré como regalo para mi novia, fuimos a acampar en enero a las faldas del volcán Iztaccíhuatl, México. Estuvimos a una temperatura de aproximadamente 3°C y se sintió muy cómoda, cabe recalcar que durmió con ropa normal de campo, calcetas de merino y una chamarra para -5°C.

Do love this bag just wish it was a smudge bigger, little hard zipping it fully shut but once you figure it out it’s pretty easy. I used a fleece liner and had a wool blanket over me with a good pad under me and was nice and toasty in 0 degrees Fahrenheit weather. Also wish the head part would wrap around your head more but it’s good enough, a pillow insert would be awesome too . With the compression sack it comes with you can really compress it down. For reference I’m 5ft 10 in and weigh 250, I have pretty wide hips and broad shoulders so that’s most of the reason it’s a little snug, plus I was using the liner. If you’re looking to solely rely on this to keep you warm in 0 degree weather make sure you have a good insulated sleeping pad and at least a wool blanket to throw over. Would much rather pay $100 for this and a $60 sleep pad and a $25 wool blanket then the $500 and up 0 degree bags. If you don’t want to pack a blanket maybe look into bivvy sack for the bag to help keep you warm.

For the price, no other sleeping bag comes close to the Teton Sports Leef 0-degree sleeping bag. I'm 6-foot and broad-shouldered, and found the smaller Teton Sports 20-degree Trailhead bag to be much too narrow in the shoulders to be used as anything other than a makeshift quilt. To its credit, the Trailhead bag kept me warm, even unzipped for use as a quilt, when temperatures dropped to the middle and lower 40s ... but I can use the Leef fully zipped and there's still plenty of headroom to draw the hood tight. Like all mummy bags, the Leef is confining, but as a side-sleeper it still worked for me. I couldn't roll over WITHIN the bag, but it was easy to turn myself AND the bag to the side. Like the Trailhead, the inner fabric of the Leef is a brushed material that is soft against the skin; it never feels wet, slippery or slick. And, as you'd expect, this bag feels considerably warmer as suggested by the lower temperature rating. About that rating: Like almost all sleeping bag companies, Teton Sports' temperature ratings should be considered "extreme" or "survival" ratings -- not "comfort" ratings. To figure out the temperature at which a bag will still keep you comfortable, the rule of thumb is to add 25 to 30 degrees to the advertised rating. So, with the Leef 0-degree bag, I can expect to get a decent night's sleep at 30 degrees. (To Teton Sports' credit, they tell customers upfront to be mindful of the fact that their temperature ratings are "extreme" level, not "comfort" level.) Other things to keep in mind about this bag: THE ZIPPERS -- There are two on one side of the bag, so you can leave one at the bottom and then zip the other one all the way to the top, and then, if you get warm, you can open that bottom zipper a bit for some venting near your feet. The zippers work well, and snags aren't an issue. It's odd that they placed the zippers on the left side of the bag, however, since it makes zipping things up a bit more awkward for right-handed people. THE COMPRESSION BAG: It seems durable and perfectly sized for the bag, so feeding the bag back into it is easy enough. The fully attached compression straps do a good job of minimizing the overall size. OVERALL SIZE: Even in its compression bag, the Leef is still about 50% to 75% larger than the Trailhead bag in its stuff-sack. This means it won't fit into the sleeping bag compartment at the bottom of the popular Teton Sports Scout 3400 backpack -- but of course that pack allows you to unzip that compartment so it's not walled off from the rest of the backpack. Simply unzip that compartment and then drop (or rather, wedge) the Leef into the bottom of the Scout 3400 from the top opening of the backpack. You'll see it eats up close to half the 3400's available space, so if you're upgrading from the Trailhead bag to the much larger Leef, you may also want to upgrade your pack from the Scout 3400, which has a 55-liter capacity, to the Teton Sports Explorer bag, which comes in both a 65-liter and a 75-liter size. >>>UPDATE: The long version of the Leef sleeping bag is far too big to fit inside the sleeping bag compartment of even the 75-liter Explorer backpack, which is a real disappointment. I assumed Teton Sports would have upsized the sleeping bag compartment of its larger backpacks so they would accommodate the company's own larger-sized sleeping bags -- but they did not. I will still be able to haul the Leef inside my Explorer backpack by opening up the segregated compartment and inserting and removing the Leef from the top of the Explorer, but of course that means I'll have to take out EVERYTHING in the pack each time I need to access or re-pack the Leef. That's not something anyone would want to do in the rain...
