The Slumberjack Boundary is the lowest priced sleeping bag we tested. If you are looking for an inexpensive bag that you can throw in your car for any summer frontcountry excursion, from camp-outs to music festivals, the Boundary could be a good choice. With the cheap price tag comes cheap materials, and the 20 degree temperature rating is overestimated by far. For just $30 more, you can get the more comfortable Marmot Trestles 30 - Women's. For twice the price (but still under $200), you can get Kelty Cosmic Down - Women's, which presents a far higher value with higher quality materials and more warmth. The Cosmic Down is our Best Buy winner and we think it provides more bang for the buck than the Boundary.

Our Analysis and Test Results
An inexpensive and durable sleeping bag, the Boundary can be thrown in your car for any summer excursion; it will keep you warm in temperatures down to the low 40s.
This contender is rated to 20 degrees Fahrenheit but is not EN rated. This rating feels more like a guess than science. It has decent feeling synthetic fill, but we would not trust it to temperatures as low as 20F. It kept us warm in the low 40s, but we are skeptical that it would keep us warm in temps any cooler than that. If you are looking for something that can handle colder conditions, the warmest bag we tested was the REI Joule.
We are pleasantly surprised that the Boundary only weighs 2 lbs 8.4 oz, which puts it in the middle of the pack weight-wise. It is lighter than both the Nemo Celesta and the Top Pick winning Sierra Designs Backcountry Bed 800. It is also the lightest of the synthetic bags, 8 ounces lighter than the Mountain Hardwear Heratio, but not as warm.
The Boundary is a pretty standard sized and shaped mummy bag, but it provides enough space inside to move around. We think it is relatively comfortable, and like the lofty, cushy feel of its synthetic fill, but think the shell material feels rough.
We like the shell materials on the Big Agnes Roxy Ann 15 and the comfortable, unique shape of the Sierra Designs Backcountry Bed 800 -Women's much more than the Boundary.
Slumberjack includes a medium sized stuff sack for the Boundary, but not a larger storage sack. This is a problem because you should never leave your sleeping bag compressed, as it crushes its loft and makes it less warm over time. With a better compression sack, the Boundary could be compressed slightly smaller than with the stuff sack provided, but it is still quite bulky. Check out our Best Sleeping Bag Stuff Sacks article to help you choose a great compression sack for your sleeping bag.
This bag is fairly bare bones, as it should be for the price tag. We like the two different drawcords for the hood and chin so you can differentiate between the two in the dark when it is cold.
We had to laugh when we read that one of Slumberjack's selling features for this bag is a "Unique 'flip over' hood [that] can be turned inside-out for the option of a flat or contoured hood." Classic! You could do this with any mummy bag, but Slumberjack is just the only company to point out the obvious! The model does not have any other bells or whistles, and no small stash pocket is included.
The Boundary is a great choice for any activity where you don't want to risk damage to an expensive bag. We think it is best suited for a child or teenager's sleepovers, music festivals, and front country camping in warm weather.
This bag's synthetic insulation will help keep you warm when things get damp, but otherwise, it is not very versatile because of its weight and bulk.
The Boundary's $60 price tag can't be beaten. It is a great value for a sleeping bag that you can take anywhere. If you are looking for a great high-quality sleeping bag that you can depend on in the backcountry, we would recommend the Rab Neutrino 400 - Women's. We also think that The North Face Cat's Meow 22 - Women's is a warmer, more reliable synthetic sleeping bag for a low price tag.
Great for all your car-camping needs, this inexpensive workhorse of a sleeping bag is a no-brainer. Keep it in your car for emergencies or get one for your child's back-yard campouts; just don't plan on taking this one on extended backpacking trips.
