A good night’s sleep can make all the difference when you’re camping. Whether you’re spending a weekend at a campground, exploring the outdoors, or setting up a comfortable basecamp, choosing the right sleeping mat is essential.
The Sea to Summit Camp Plus Sleeping Mat is designed for campers who want more cushioning, warmth, durability, and adjustable firmness without moving all the way into the premium camping-mattress category.
With its self-inflating design, 7 cm of thickness, body-mapped insulation, and an ASTM-tested R-Value of 5.3, the Camp Plus is built to provide comfortable sleeping conditions through extended three-season conditions and into colder camping environments.
What Is the Sea to Summit Camp Plus Sleeping Mat?
The Sea to Summit Camp Plus is a self-inflating sleeping mat designed primarily for camping, car camping, hunting, paddling, and basecamp adventures.
Unlike a simple foam sleeping pad, the Camp Plus combines open-cell polyurethane foam with air to create a thicker and more cushioned sleeping surface. When the valve is opened, the foam expands and draws in air. You can then add a small amount of air to adjust the firmness to your preferred sleeping style.
The result is a sleeping mat that provides considerably more cushioning than many basic camping pads while remaining relatively simple to set up.
Why Choose the Sea to Summit Camp Plus?
One of the biggest advantages of the Sea to Summit Camp Plus SI Sleeping Mat is its combination of comfort and durability.
The mat is approximately 7 cm (2.76 inches) thick, giving you a generous layer between your body and the ground. Sea to Summit also states that the Camp Plus provides approximately 33% more thickness than standard mats.
This extra thickness can be particularly useful for side sleepers or campers who find thin sleeping pads uncomfortable.
1. 7 cm of Comfortable Cushioning
Sleeping directly on uneven ground can create pressure points around your hips, shoulders, and back.
The Camp Plus addresses this with a thick foam construction that provides a more supportive sleeping surface.
You can also adjust the firmness by adding air, allowing you to find a balance between softness and support.
2. ASTM R-Value of 5.3
Insulation is just as important as cushioning when choosing a camping sleeping pad.
The Camp Plus has an ASTM-tested R-Value of 5.3, which means it offers substantial resistance against heat loss to the ground.
This makes it a strong choice for campers who want a sleeping mat suitable for extended three-season use and colder camping conditions.
3. Body-Mapped Air Zone Construction
Sea to Summit uses Air Zone body-mapped insulation to place insulation where it is needed while reducing material in less critical areas.
This design helps balance comfort, insulation, and weight instead of simply adding foam throughout the entire mat.
4. Durable 75D Recycled Polyester
Camping equipment has to deal with rough surfaces, dirt, moisture, and repeated use.
The Camp Plus uses rugged 75D woven polyester with TPU lamination, and the current model incorporates certified recycled polyester.
This makes the Camp Plus particularly appealing for car camping, established campsites, overlanding, and other situations where durability is more important than achieving the absolute lowest possible weight.
Camp Plus Sleeping Mat Sizes
The Sea to Summit Camp Plus is available in several sizes, allowing campers to choose between compactness and additional sleeping space.
Current specifications include:
| Size | Dimensions | Weight |
|---|---|---|
| Regular | 72 × 22 × 2.76 in | 37.0 oz |
| Regular Rectangular Wide | 72 × 25 × 2.76 in | 48.3 oz |
| Large | 78 × 25 × 2.76 in | 45.7 oz |
| Large Rectangular | 78 × 25 × 2.76 in | 52.7 oz |
The exact packed weight and dimensions vary by size.
The Regular is a good option for campers who want to keep the packed size and weight lower, while the wider and larger versions provide more room to move during the night.
Is the Sea to Summit Camp Plus Good for Backpacking?
The Camp Plus can be used for short hikes to a campsite, but it is not designed primarily as an ultralight backpacking sleeping pad.
Sea to Summit itself notes that the Camp Plus is somewhat heavy for backpacking-focused trips.
For car camping or basecamp adventures, however, the additional weight is much less significant.
If your priority is carrying the lightest possible sleeping system deep into the backcountry, a model such as the Sea to Summit Ether Light XT or another lightweight backpacking-oriented mat may be more appropriate.
If your priority is comfort, durability, warmth, and easy setup, the Camp Plus becomes much more attractive.
Camp Plus vs. Sea to Summit Ether Light XT
Both products belong to the Sea to Summit sleeping system, but they are designed with different priorities in mind.
The Camp Plus focuses heavily on durable construction, cushioning, and camping comfort. The Ether Light series is more oriented toward lightweight outdoor sleeping systems.
This is an important distinction when choosing your sleeping pad.
Choose the Camp Plus if you:
- Primarily go car camping
- Want a thicker sleeping surface
- Prefer a durable outer fabric
- Want strong ground insulation
- Don’t mind carrying more weight
- Want adjustable firmness
Consider an Ether Light model if you:
- Frequently backpack long distances
- Prioritize lower weight
- Need a more compact sleeping system
- Want to reduce the weight of your entire backpacking setup
The right choice ultimately depends on how you camp.
Camp Plus vs. Comfort Plus SI
Sea to Summit also offers the Comfort Plus SI, which shares the same basic foam-core insulation concept.
According to Sea to Summit, the biggest difference is the fabric. The Camp Plus uses 75D woven polyester on the top and bottom, while the Comfort Plus uses a softer stretch-knit polyester on the sleeping surface.
The Camp Plus is therefore an appealing choice if you prefer a more durable, tactile fabric and don’t need the softer feel of the Comfort Plus.
How to Use the Camp Plus Self-Inflating Mat
Setting up the Camp Plus is relatively straightforward.
Step 1: Find a Suitable Location
Clear away sharp rocks, sticks, and other objects that could potentially damage your sleeping mat.
Step 2: Unroll the Mat
Place the Camp Plus where you want to sleep and unroll it completely.
Step 3: Open the Valve
Open the XPEL valve and allow the open-cell foam to expand.
The foam naturally draws air into the mat as it expands.
Step 4: Adjust the Firmness
Once the mat has mostly inflated, add a small amount of air if necessary.
You can adjust the firmness according to your sleeping position and personal preference.
Step 5: Pack It Away
When you’re ready to leave, the XPEL valve helps with quick deflation and allows the mat to be rolled into a compact package.
Who Should Buy the Sea to Summit Camp Plus?
The Sea to Summit Camp Plus Sleeping Mat is particularly well suited to campers who value comfort over ultralight pack weight.
It is an excellent option for:
- Car campers
- Weekend campers
- Basecamp adventures
- Overlanding
- Hunting trips
- Family camping
- Extended campground stays
- Campers who prefer thicker sleeping pads
- People who want a durable sleeping mat
It can also work for shorter backpacking trips when comfort is more important than minimizing every ounce.
What About a Sea to Summit Pillow?
A sleeping mat is only one part of a comfortable camping sleep system.
Pairing the Camp Plus with a dedicated Sea to Summit pillow can make your sleeping setup significantly more comfortable, especially if you’re spending several nights outdoors.
A supportive camping pillow can also help complete your sleep system without taking up much additional space in your gear bag.

Final Verdict
The Sea to Summit Camp Plus Sleeping Mat is a strong choice for campers looking for a combination of comfort, warmth, durability, and easy setup.
Its 7 cm thickness, ASTM R-Value of 5.3, body-mapped Air Zone construction, and durable recycled 75D polyester make it particularly well suited to car camping, basecamp adventures, and campers who don’t want to sacrifice comfort to save a few ounces.
It isn’t the lightest sleeping mat for serious ultralight backpacking, but that’s not really its purpose.
For campers who want to arrive at camp, set up comfortably, and enjoy a good night’s sleep, the Sea to Summit Camp Plus SI deserves a place on the shortlist.
A comfortable sleeping system starts with the right foundation—and the Camp Plus provides exactly that.
