Big Agnes Q-Core SLX Petite Review

Insulated Q-Core SLX vs. Q-Core SLX

Big Agnes tells us that the updated Insulated Q-Core SLX is essentially the same design as last year's pad — they've just changed the name and included an inflation sack. The previous model was also insulated; this year's model, however, has changed some of the internal organization of the insulation. The R-Value is 3.2. The model we tested, the “Petite” size, is no longer referred to as petite and is just denoted by its dimensions of 20" x 66". The latest model is shown below in green (first image) followed by the older model in yellow.

We're now linking to the latest version of the pad and expect it to perform similarly as the model we tested here.

Hands-On Review of the Q-Core SLX

We feel like we're on a big floating raft in the ocean on this colossal sleeping pad. The Q Core SLX is super thick, and you'll find yourself floating above your tent mates.

Warmth

Big Agnes says the Q Core SLX is insulated with WRM high-loft synthetic insulation. Based on the pack size of this pad, we don't think there is much in there. You can feel a small layer of it when it is deflated, but based on our experience sleeping on this pad, it doesn't feel like it is very insulated.

The Q Core SLX now has an R-value of 3.2; this is at the lower end of warmth, and we would hesitate to take this pad out in cold temperatures unless you're bringing a closed-cell foam pad like the Therm-a-RestZ Lite Sol. We would not recommend using it in a winter camping setting. There is a lot of cold air moving around under your body in this super thick model, with only a thin layer of insulation to protect you from the ground.

Comfort

We had high hopes in this category for the Q Core SLX, though we've learned that thicker doesn't always mean better. It is a super cushy pad that is 4.5 inches thick. If you are a side sleeper, this could be an excellent choice for you because it's so thick your shoulders won't touch the ground. The Q Core SLX does have I-Beam construction for stability, which we noticed; however, it takes some getting used to the boaty-ness of this pad. We do like that the outer chambers are bigger and give you a cradled feeling, keeping you in the middle of the pad.

The pad's materials are quite slippery, so if you're camped on a hill, you may find yourself at the bottom of it quickly. This model also has a one-way inflation valve that makes it easy to adjust how much air you want to keep you comfortable. It also has a gaping valve to deflate it very quickly. These valves are significant, and if they're on top when you're sleeping, you may have the indent of them on your face in the morning.

Durability

Big Agnes has used “Aviation grade TPU lamination technology” as a coating on the ripstop material, claiming it is 25% more durable than the previous model.

Weight

This huge air mattress is surprisingly light compared to its inflated size. The 66-inch size, which we tested, is one of the lighter models in this review, pretty light compared to how big it gets. By our measurement, it weighs 16.6 ounces.

Packed Size

This one also packs down impressively small, coming in neck and neck with the smallest of the bunch.

Value

The Q Core SLX is a decent value for a high-quality pad. If you're planning on spending a lot of time backpacking, we'd recommend dropping the extra few dollars to purchase the NeoAir XTherm instead; it will save you four ounces, and you'll have more space in your pack.

Conclusion

We would recommend this pad for all your summer base camping and backpacking needs. We would hesitate to stretch the Q Core SLX's use into the colder seasons unless you pair it with a foam pad for better insulation. If you're a side sleeper, this could be the answer to your shoulder woes as it will keep those shoulders off the ground. It is a cushy, comfortable pad that is light and won't weigh you down on extended backpacking trips.
