Big Agnes Q-Core SLX vs. Deluxe Sleeping Pad

Both Q-Core SLX and Deluxe sleeping pads are insulated options from Big Agnes. They are an ideal mix of ultralight materials and 3-season comfort. These pads are a great option for backpackers who value a good night’s sleep. While both of these pads provide a similar set of features, they differ in terms of price, weight, comfort, and insulation. The Q-Core SLX is slightly cheaper but it also has a relatively low 3.2 R-value so it has a little warmth. The Q-Core Deluxe, on the other hand, is slightly expensive but has a higher 4.3 R-value and it is much warmer. Below is an in-depth comparison of the two sleeping pads.

Big Agnes Q-Core SLX

Big Agnes Q-Core SLX
Weight: 1 lb. 2 oz.
Thickness: 3.5/4.25 inches
R-value: 3.2
Dimensions: 20 x 72 inches

This pad is made from rip-stop nylon, which is internally sealed to be totally waterproof and airtight. The material offers a good balance of weight savings and durability. Inside, synthetic insulation and a heat reflective material help to trap body heat and reflect it back to you to keep you warm. The internal offset I-beam structure and quilted outer pattern make the pad stable and comfortable and reduce that pool raft feeling you get on some fewer premium products. Additionally, a large outer chamber keeps you from rolling off and cradles you comfortably in the center of the pad.

At 3.5 inches thick when fully inflated, this pad is incredibly comfortable even for side sleepers like me. Another great feature here is the valve. It sits flat against the surface so it’s easier to roll up and store. This is a high-volume valve, which makes for easy inflating and deflating. It also has a pressure adjustment button so you can fine-tune the pad to your comfort. Big Agnes includes an upcycled inflation sack with each pad, which saves you from having to inflate the pad by breath. But, if you’re ever in a pinch and need to inflate the pad by mouth, Big Agnes protects the inside of the pad from moisture and buildup of mildew by using an anti-microbial coating.

This pad is sold in several different sizes including a double-wide option. So be sure to check out the full specs to determine the right option for you. Along with each pad, Big Agnes includes a stub sack and repair kit as well as the inflation sack. If you’re seeking a lightweight and comfortable addition to your kit with insulation for three-season use, make sure to check out the Big Agnes insulated, Q-Core SLX.

What I like: Lightweight, a good option for 3-season adventures, packs reasonably small, and a comfortable sleeping surface

What I don’t: Lightweight means thin materials, isn’t as durable

Big Agnes Q-Core Deluxe

Big Agnes Q-Core Deluxe
Weight: 1 lb. 9 oz.
Thickness: 3.5/4.25 inches
R-value: 4.3
Dimensions: 20 x 72 inches

Big Agnes Q-Core insulated Deluxe is a comfy sleeping pad for cold nights offering comfort on the top and warmth for 3+ seasons of adventures inside. The quilted top uses soft and laminated stretch fabric to provide pillow-like next-to-skin comfort. There is alternating I-beam baffle construction, which reduces weight while creating a thick cushion and a stable base for comfortable sleeping. Inside, there is integrated PrimaLoft Silver insulation that keeps you insulated from the cold ground. A thin layer of heat reflective barrier returns some of your lost body heat back to you. Combined, these internal features give this pad an R-value of greater than 4, and that will keep you warm on all but the coldest nights.

If you want to toss and turn, the large chambers on the side create rails to keep you on the pad at night. There are two low-profile valves. One allows inflation and fine-tuning adjustments while the other is for rapid deflation. An up-cycled inflation sack is included so you can inflate the pad without straining your lungs. This pad offers you a quilted comfortable sleeping surface, an internal layer of synthetic insulation, and heat-reflecting materials that promise warmth.

What I like: A good option for side sleepers, hardly makes a noise, materials feel pretty durable, very warm

What I don’t: A little heavier than the SLX but that extra weight adds to the warmth.

Which one is right for you?

Big Agnes Q-Core SLX Sleeping Pad

Both Q-Core SLX and Deluxe are lightweight sleeping pads for 3-season adventures. The Q-Core Deluxe delivers a little more warmth but it comes with a few extra ounces. It has an R-value of 4.3 and weighs around 25 ounces. If weight is not a critical consideration and you are looking for a pad that can provide a little more warmth, go for the Q-Core Deluxe because it’s going to provide the maximum warmth. On the other hand, if you are an ounce counting backpacker and looking to shave some weight, go for the Q-Core SLX. It’s not the warmest sleeping pad but it has enough insulation for 3-season adventures.
