Our Verdict

This plush car camping mat is comfortable, and a great color, but we found the Women's Comfort Plus heavy, hard to pack and overpriced compared to its competitors. Sea to Summit has rolled out a new, comprehensive line of women's sleeping pads, but this one isn't our favorite.

Our Analysis and Test Results

The Women's Comfort Plus Self-Inflating Sleeping Mat, not to be confused with the Sea To Summit Comfort Plus Insulated Short, is comfortable, but also heavy and bulky. We like its multi-function valve and stuff sack pump system, which allow for easy inflation and immediate deflation when it's time to pack up.

Warmth


Along with the REI Air Rail Plus, the Comfort Plus has the highest R-Value and is the warmest bag in this women's review. It has thick foam insulation in it that will shield you from the cold ground. For this reason, you could stretch this mat into 4 season camping territory.

Comfort


This pad is very comfortable, thanks to the thoughtfulness that Sea to Summit has put into the creation and shape of their women's pads. They are an oval shape, whereas the men's products are more of a triangle, tapered shape. This means that the Comfort Plus is wider at the hips than the shoulders which work really well with most women's dimensions. For this reason and the fact that this pad is thick and cushy, we think it's pretty darn comfy. We like the squishy stretchy feel of its upper knitted polyester material; it feels more yielding than other thick pads like the Big Agnes Q Core SLX that are just plastic and air, with no padding.

Although the Comfort Plus SI is self-inflating with a one-way valve it still needs a few breaths to get fully inflated. It does not come with a pump sack like the other Sea to Summit models.

Durability


Because of the amount of foam in this mat, even if it sprung a leak, it would still insulate you from the ground more than a less-durable pad with no foam. The materials seem relatively durable and abrasion resistant, although 30 Denier material is not as durable as the Air Rail's 75D.

Weight


Here's where things start going downhill in the metrics for the Comfort Plus, although this is not meant to be an ultralight pad in the first place. Weighing in at a hefty 34.4 ounces, it's the heaviest mat in this review. We would not carry this with us over long distances; instead, we'd let our vehicle do the heavy lifting on car-camping trips.

Packed Size


Due to the huge amount of foam that the Comfort Plus contains, it's quite bulky. It's also challenging to get back into its stuff sack. There is meant to be a feature where you can twist a piece of the valve to stop the self-inflating part of the pad while you roll it up, but we couldn't figure it out and couldn't find instructions online. It is one of the bulkiest pads in this review.

Best Application


The Comfort Plus is a great choice for a car camping pad. It is comfortable and warm for chilly nights in the campground, but heavy and bulky so we would not take it backpacking.

Value


Retailing for $140 we do not think that the Comfort Plus Self-Inflating Sleeping Mat is an incredible value for a car-camping sleeping pad. Other similar products are much cheaper like the Air Rail and the Therm-a-Rest Trail Lite Women's, which are also lighter and more packable for short backpacking trips.

The Comfort Plus is in fact heavier and bulkier than the TrailLite.

Conclusion


We applaud Sea to Summit for their new thoughtful women's products, but we think that the Comfort Plus is overpriced for what it is (a comfortable and warm car camping pad). We would reach for the less-expensive models with comparable comfort and warmth over the Comfort Plus.
