Sleep Systems Episode 4: Sleeping Pads--Foam, Air, & Self Inflating
Sleeping Pads: Your Unsung Hero for Comfort and Warmth Outdoors
In our "Everything Sleep Systems" series, we're uncovering all the secrets to a great night's sleep in the wild. Today, we're talking about sleeping pads, a piece of gear that we argue is arguably more important than your sleeping bag when it comes to both comfort and overall warmth!
As Jay highlights, if you're not comfortable, you're not sleeping, and if you're not sleeping, you're definitely not enjoying your time in the backcountry. Your sleeping pad acts as a crucial insulating barrier between your body and the cold ground, which can suck away your warmth surprisingly quickly.
Let's explore the different types of sleeping pads to help you find your perfect match:
1. Foam Sleeping Pads: The Lightweight & Durable Classic
Foam pads are the most basic and often the most inexpensive type of sleeping pad. They are essentially a layer of closed-cell foam that provides a minimal barrier from the ground.
Pros of Foam Pads:
Most Inexpensive: Very budget-friendly, making them accessible to everyone.
Lightweight: They add virtually no weight to your pack.
Easy to Use: No inflation required! Just unroll or unfold, and you're set. Perfect for quick setups.
Durable & Puncture-Proof: You don't have to worry about holes or leaks, making them very reliable.
Cons of Foam Pads:
Low R-Value: (We'll dive deeper into R-value in our next episode!) They offer minimal insulation from the cold ground, making them less suitable for colder conditions.
Minimal Comfort: As Jay puts it, "they're the worst" for comfort. You'll likely feel every rock, root, or lump on the ground beneath you.
Bulky: Even when folded or rolled, they take up significant external pack space.
Best for: Budget-conscious campers, those prioritizing durability over comfort, emergency backup, or for adding extra insulation underneath another pad.
2. Self-Inflating Pads: A Hybrid of Comfort & Convenience
Self-inflating pads incorporate open-cell foam inside an airtight shell. When the valve is opened, the foam expands, drawing air into the pad. Most still require a few extra breaths to reach full firmness.
Pros of Self-Inflating Pads:
Good Comfort: They offer a noticeable upgrade in cushioning compared to foam pads, absorbing some of the unevenness of the terrain.
Easier Setup: They do most of the work themselves, requiring minimal lung power.
Durable (More than Inflatables): Generally more robust than full air pads, with less risk of major punctures.
Cons of Self-Inflating Pads:
Bulky & Heavy: These pads tend to be significantly heavier and bulkier than inflatable pads, limiting their suitability mostly to car camping. Jay notes his personal Sea to Summit pad weighs around 6 pounds!
Moderate Insulation: While better than foam, their R-value may not be as high as dedicated inflatable pads designed for cold weather.
Best for: Car campers, those seeking a balance of comfort and convenience, and campers who want more cushioning without the effort of full inflation.
3. Inflatable Pads: The Modern Standard for Backpacking Comfort
Inflatable pads are essentially air mattresses designed for the backcountry. They offer significant thickness and support, relying on trapped air for insulation.
Pros of Inflatable Pads:
Superior Comfort: They provide excellent cushioning, allowing you to float above uneven terrain. You can often get pads 3-6 inches thick!
Excellent Insulation (High R-Value): Many modern inflatable pads incorporate internal baffles or insulation to achieve very high R-values, making them incredibly warm in cold conditions. (Drew mentions a 4.7 R-value pad that weighs only about a pound!).
Lightweight & Compact: They pack down remarkably small and are very light, making them the preferred choice for backpacking and thru-hiking.
Cons of Inflatable Pads:
Puncture Risk: The biggest vulnerability is punctures. A small hole can ruin your night's sleep (as happened to one of Drew's buddies in South Carolina). Most come with patch kits, but no one wants to fix a leak in the middle of the night!
Inflation Time: While many come with pump sacks or can be inflated with mini-electric pumps, blowing them up manually can be exhausting, especially at altitude. (Jay loves the pump sacks – a game changer!)
Noise: Some inflatable pads can be surprisingly noisy. Jay describes one of his as "like sleeping on a roll of aluminum," which could be a deal-breaker for light sleepers. Always test the fabric noise before buying!
Cost: Quality inflatable pads can be a significant investment.
Best for: Backpackers, thru-hikers, cold-weather campers, and anyone prioritizing maximum comfort, warmth, and minimal pack size.
