The hugely popular Riff has been updated but still retains the spoon shape for side sleepers, with generous room at elbows and knees, and allows for maximum temperature regulation with Nemo's award-winning Thermo Gills feature.

Nemo says:

Riff™ is NEMO’s top-of-the-line backcountry-oriented Spoon™ shaped sleeping bag. This pinnacle performance 3-season 800FP down bag offers a more athletic cut, designed for side sleepers who prefer space-saving packability and shaving critical ounces for long hours on the trail.

Seventy percent of people sleep on their side, yet mummy bags are not designed to accommodate this. NEMO’s unique Spoon™ shaped bags offer more room at the elbows and knees, allowing side sleepers to shift positions comfortably throughout the night.

This popular bag is loaded with features, including Thermo Gills™ that help regulate temperature during the night, Blanket Fold™ that provides tucked-in comfort, and a waterproof/breathable footbox to withstand tent condensation. Left-sided zippers on Men’s and right-sided zippers on Women’s allow Riff™ to zip together for a double bag.

The highly successful Nemo Riff 15 Sleeping Bag has been updated for 2020 with new fabrics at a lighter weight. It retains the comfortable and spacious 'spoon' shape so it is still wider at the elbows and knees, meaning you can toss and turn as much as you want, without the bag restricting you. 

The main updates have seen the design streamlined to shed weight, without losing the spoon shape and the benefits from it. Despite using less down in terms of weight, the comfort limit of the bag has stayed the same meaning that the overall weight has been further reduced. The zipper system has also been improved to make access easier. 

Nemo have kept the innovative Thermo Gills which are shown by the 2 slits down the center of the bag. They unzip to let warm air out if you get too hot at night, allowing you to vent body heat without letting cold drafts in and they work really well, especially in changeable conditions. They have also increased the bags water resistance with waterproof footbox and hood and further DWR treatments on the other fabrics.

Another feature it has that is quite unique to Nemo bags, is the Blanket Fold. Like a comforter at home, the blanket fold gives some extra material to snuggle around your face and helps to control temperature. The Forte bags are still able to zip together with the womens bags if that is something that you want in your bag.

Heavier than I’d like, but …

Really good sleeping bag if you’re like me and shift around a lot at night. Toasty warm and really comfortable. I’m a light sleeper generally, but sleep really well in this. Packs up small. Not the lightest by any stretch, but it’s a keeper. I’ll (just about) take that extra weight for a decent night’s kip.
