Trailhead™ Synthetic Sleeping Bag (30°F & 20°F)

MOST GOOD ADVENTURES START WITH A TRAILHEAD

$139.00 – $159.00

Sleeping Bag Temperature Ratings Explained

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 23ºF means a man should be comfortable down to air temperatures of 23ºF. The same bag will also have a Comfort limit, in the realm of 32°F, so a woman would be comfortable down to an air temperature of 32ºF. 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 27ºF / -3°C, choose a bag with a gender-appropriate rating of 23°F / -5°C, plus a sleeping mat with an R-Value of 2.5 to 3, and consider a Reactor thermal liner.

Description

If you are new to outdoor recreation, or you only camp occasionally, the Trailhead™ synthetic sleeping bag is a great value-oriented option. However, the modest price tag doesn’t mean we’ve cut corners on comfort and versatility. Like all Sea to Summit synthetic 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 sleeping bag can be opened flat and used as a quilt.

The tapered-rectangular cut of the Trailhead™ gives you plenty of room to move, regardless of your sleeping position.

Is this synthetic sleeping bag…?

  • Warm enough for colder weather camping or travel? Yes. The WaveLoft™ insulation construction maximizes loft and results in a temperature rating of 20°F. Frequent cold-weather campers might look to the Traverse™ sleeping bag series. In cool or cold conditions, make sure you have a higher R-Value sleeping mat like the Comfort Light Insulated.

  • 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 fully-flat comforter in really warm weather.

  • 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, the Traverse ™ sleeping bag series would be your synthetic-insulated choice

Technical Features

WaveLoft™ Construction

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.
