The EN Rating scale is a scientific test to determine the warmth of a sleeping bag. The test produces a Lower rating (for male sleepers) and a Comfort rating (for female sleepers). Both are listed in the features table on the product page.
A unisex sleeping bag with a Lower limit of -10°C means a man should be comfortable down to air temperatures of -10°C. The same bag will also have a Comfort limit, in the realm of -3°C, so a woman would be comfortable down to an air temperature of -3°C. These ratings require a sleeping mat with an R-Value appropriate for expected ground temperatures – without this, the sleeping bag itself is unlikely to keep the sleeper warm enough.
A variety of factors impact sleeping bag warmth - the above temperatures are merely guidelines, not guarantees. It’s important to think of a sleeping bag, an appropriately insulating sleeping pad and a liner as a sleep system. For example - if you plan on sleeping in nighttime air temperatures of -3°C, choose a bag with a gender-appropriate rating of -5°C, plus a sleeping mat with an R-Value of 2.5 to 3, and consider a Reactor thermal liner.
If you are new to outdoor recreation, or you only camp occasionally, the Trailhead synthetic mummy sleeping bag is a great value option. However, that doesn't mean we've cut corners on comfort and versatility. Like all Sea to Summit synthetic mummy sleeping bags, the Trailhead utilizes WaveLoft construction to allow the insulation to expand out into air-trapping curves for maximum warmth.
As the temperature rises, the full-length zipper (which curves around through the foot box) allows you to sequentially increase ventilation to the point where the mummy sleeping bag can be opened flat and used as a quilt.
The tapered-rectangular mummy cut of the Trailhead gives you plenty of room to move, regardless of your sleeping position.

WaveLoft is a unique construction technology designed to maximize loft and minimalize insulation weight. Instead of conventional flat layers of insulation (sewn flat on top of each other) or shingle layers (sewn in diagonally overlapping layers), WaveLoft creates curved layers which expand out from the shell to trap the greatest amount of air possible at a lower overall weight than existing synthetic insulation constructions. WaveLoft is used on all Sea to Summit synthetic-insulated sleeping bags, regardless of price level.
Frequently Asked questions
Warm enough for colder weather camping or travel?
Perhaps. You would need the Th III - its Waveloft insulation maximizes loft. Pair it with a 3.5+ R-Value sleeping mat (perhaps Comfort Light Insulated) and consider a Reactor liner.
Suitable for summer temperatures?
Yes. A full-length side zipper (with two zipper sliders) that extends through the foot box can be opened for ventilation or to turn the Trailhead into a comforter.
Able to be zipped to another sleeping bag?
No. If you are looking to couple your sleeping bag to a Sea to Summit Unisex model, consider the Traverse synthetic sleeping bag
