Rated 5 out of 5

Room for days

Got the Forte 35 degree WIDE long sleeping bag and this thing is awesome. Perfect for summer camping. The older I get, I have less need for a super packable bag, more comfort and car camping these days. That being said, it is still a very packable bag. This bag delivers on comfort and room for days. I am 6'3" and have a little room to spare. The spoon shape, alongside the wide feature, is amazing for comfortable nights. I can finally sleep on my side and maneuver inside my bag. Also, the blanket fold collar is great. You can wrap it around your neck and seal yourself in, or you can tuck all the way in and place the collar into the mummy head of the bad and completely seal warmth in. I was so impressed with the style, I purchased a Disco 15 degree for the colder nights.

Well thought-out design

So far I've only done a pre-trip test, but I was impressed enough with the details that I'm pretty sure this is the best sleeping bag I've had. The shape allows for natural movement and none of that constricted feeling, while still saving some pack space and minimizing deadspace. The gills are well thought-out, as are the neck baffle and every other detail. I haven't bought a sleeping bag in a while, and I'm super impressed with this one and looking forward to logging some nights in it soon.

Great summer bag.

Just bought this bag for a 5 day bikepacking trip. Low temps were in upper 40s and highs in the upper 80s. It was the perfect bag for me at these temperature ranges. I like that it packed small enough to mount to my handlebars. The zip vents were a nice feature that I didn't think I needed but used on a warmer evening. Happy camper.

Great bags

Forte is my go-to for Car/overland camping. I'm a side sleeper that likes a little extra wiggle room and this is perfect! Going to take advantage of the sale and upgrade my 20 forte and Disco 30 as well.

Warm, Roomy, and Built for Camping!

The Forte 20 has been fantastic so far. I went with the 20° because I'd always rather be too warm and vent the bag than end up cold when temps drop lower than expected. The Thermo Gills work great for dumping a little heat when needed. I also chose the regular wide version since I toss, turn, and sleep on my side constantly, especially while camping. The extra room makes a huge difference and the spoon shape actually lets you move naturally without feeling restricted. The hood, draft flap, comfort, packed size, and overall design are all excellent. Nemo really nailed the balance between comfort and packability. The updated storage bag is also a nice improvement over the older mesh sack. It takes up less space and sits nicely on a shelf. I also own the Disco (down), which is another awesome bag. The Forte packs down surprisingly small for a synthetic bag, but compared to my Disco down bag it still takes up close to twice the space in the compression sack. Just mentioning that for anyone comparing synthetic vs down options. I did catch the zipper a couple times, but honestly that feels like part of the sleeping bag experience no matter the brand. At least it's way better than fighting with old sleeping bags from the '90s. Overall, this has quickly become one of my favorite pieces of camping gear.
