The Heratio 15 is one of Mountain Hardwear's offerings for the (somewhat) budget shopper. It's a decent down bag that could be a good choice for a woman venturing into longer backpacks in cooler, three season temperatures. We took it out during the late spring and pushed it to its temperature limits and think its 15-degree rating to be ambitious. It is simple, and light, but not the lightest it could be, and we wish the materials were slightly higher quality.

Our Analysis and Test Results
The Heratio's EN rating is 15 degrees, the lowest temperature rating in this review, but we did not find this bag as warm as the Feathered Friends Egret. We took this bag out during late spring conditions and spent a few nights camped on snow (with a foam pad and Therm-a-Rest NeoAir XLite Women's sleeping pad) and were on the chilly side. Temperatures got down to the low 20's but never as cold as 15, so we are skeptical of this rating. We think that a higher quality 700 or 800 fill down would have helped. We missed a draft collar on this bag to keep cold drafts out when the temperature dipped and think a bag that's rated to this temperature would benefit from one. The Heratio has one ounce more down fill than the men's version (the extra is added to the foot and torso areas).
The Heratio has water-resistant coated down, as well as a shell coated with DWR treatment for when you want to sleep out, but don't have to worry about dew or moisture.
The Heratio weighs in at an unimpressive 40 ounces. Compared to its synthetic cousin the Laminina Z Flame, which weighs 55 ounces, that's pretty light, but the Heratio is 12 ounces heavier than the Rab Neutrino 400, which is significant. We think again this could be helped with a higher down fill count and lighter shell materials. We would spring for the luxurious Sierra Designs Backcountry Bed 700 Women's that weighs one ounce less.
The Heratio has a "comfort mummy" cut that is tailored specifically for women. We found it comfortable and like the gradual taper from shoulders to feet. The hood fits well; overall, the Heratio fits our 5'5" testers like a roomy glove.
Like most down sleeping bags, this model packs down quite small. It doesn't come with a compression sack which would help get it even smaller.
Mountain Hardwear provides a mesh storage bag — which we thought could be larger since the down was still being partially compressed when it was in the storage sack. This makes us feel like they were cutting corners. Otherwise, the Heratio has few bells and whistles in this department, which this is fine by us; the fewer features, the less weight!
This bag is a good choice for backpacking trips from late spring through early fall and could be a step up from your old synthetic bag. You could also shave seven ounces off of your Kelty Cosmic Down weight.
The Heratio is an "OK" value at $260. We think there are higher quality bags in this review for around the same price, like the REI Joule. We would recommend springing for the extra $40 and getting the super high quality, lightweight Sierra Designs Women's Cloud 800, our Best Buy winner.
We understand that Mountain Hardwear is offering women a more accessible down sleeping bag at a reasonable price, and we think the Heratio is an all-around decent sleeping bag. However, we wish they still made a high-quality sleeping bag like the discontinued Phantasia (for women).
