Wool Camp Pillow vs Inflatable: How to Sleep on Your Neck Outdoors

A camping pillow is the piece of the sleep system most people leave at home and then spend the night regretting. On a firm pad the neck needs real support, and the three usual answers (an inflatable, a wool-filled pillow, or a stuff sack of clothes) behave very differently at 2 a.m. This article compares them on weight, packed size, feel, noise, cold and washing, explains how to set the height for side and back sleeping on a thin pad, and covers why wool fill is the material we chose.

Why the pillow matters more on a firm pad

On a soft mattress your shoulder sinks and the pillow only has to fill a small gap. On a ¼ in wool pad or a foam pad your shoulder does not sink at all, so a side sleeper’s head is a full shoulder-width above the surface and needs a pillow tall enough to keep the neck level. A back sleeper needs the opposite: a low rest that supports the curve of the neck without pushing the head forward. Get the height wrong in either direction and you wake with a stiff neck that no bag or pad can fix. A pillow that can be adjusted between the two heights during the night is worth more than any other feature.

Camping pillow options compared

Inflatable figures are typical ranges for backpacking pillows from published specifications, not any one brand. The wool pillow is the Lucky Sheep camp pillow: wool fill in an organic cotton cover, $40.

	Inflatable	Wool-filled camp pillow	Stuff sack of clothes
Weight	2–4 oz	Light but not featherweight; it is a small pillow of packed wool, heavier than an inflatable	Nothing extra; you are carrying the clothes anyway
Packed size	Smallest; fits in a pocket	Compresses to a soft loaf; stuffs into the bag’s hood or the pack’s lid	None; it is your clothes bag
Feel	Firm, bouncy and slippery; head tends to roll off; height fixed once inflated unless you get up to adjust	Dense and even, like a small buckwheat pillow; shape it with a hand and it stays	Lumpy; depends on what is in it; reshapes freely
Noise	Crinkles with every turn	Silent	Depends on the sack fabric; nylon rustles
Cold	Cold to the cheek in the morning; condensation from breath collects on the surface	Warm to the touch; wool absorbs breath moisture instead of holding it against your face	Neutral, unless the clothes are damp, in which case cold
Sweat and moisture	Plastic surface; sweat sits on it	Absorbs moisture into the fibre and airs out in the morning	Absorbs into the clothes you will wear tomorrow
Washability	Wipe down	Cover machine washes; fill airs in the sun	Wash the clothes
Lifespan	Years; usually ends with a leak or a valve failure	Decades; wool does not clump or flatten permanently	Indefinite
Price	$20–60	$40	Free

Read the weight row honestly: if you are cutting every ounce, the stuff sack wins and the inflatable is second. The wool pillow is for people who have tried both and would rather carry a few more ounces than sleep on a balloon. On any trip where weight is not the whole story (weekends, basecamp, canoe and car trips, cabins) there is no contest.

Setting the height: side sleepers and back sleepers

Our founder’s method, developed over a lot of nights on thin pads, works with any pillow that can be shaped.

• Back sleeping: low and under the neck. Push the fill towards one end so it makes a firm roll, put the roll under the curve of the neck, and let the back of the head rest lightly on the pad or hang just off the far edge of the pillow. The head should not be pushed up; the neck should feel gently lengthened. After a day under a pack this is the position most people find they want.
• Side sleeping: tall enough to fill the shoulder. Fold the camp pillow in half, or stack a second stuff sack on top of the first, so the head is level with the spine rather than tipped down. Stagger the knees (top knee forward onto the pad) to take the pressure off the hip, which is the other complaint on a firm pad.
• Change position between sleep cycles. You will wake briefly a few times a night on a firm surface. Roll from back to side, refold the pillow to the new height, and go back down. Sleeping one position per cycle keeps any one spot from taking all the load.
• In a pinch: a rolled sweater under the neck does the back-sleeping job with no pillow at all. It is the one you learn on a thru-hike.

This is why an inflatable is at a disadvantage on a firm pad. It has one height, it is round in section so the head rolls, and to change it you have to sit up and fiddle with a valve in the dark. Wool and stuff sacks reshape with a push of the hand.

Why wool fill does not clump or sweat

Pillow fill has two enemies: your breath and your head. A face breathes out a good share of the half litre of water an adult loses overnight, and most of it lands in the pillow. Down and polyester batting hold that moisture between the fibres, where it makes the fill damp and heavy, and the weight of the head then packs the damp fibres into lumps. That is why a synthetic camp pillow goes flat and lumpy in a season and a down one needs a dryer to loft again.

Wool takes moisture into the fibre itself (published textile data puts wool’s regain at 13–16 % of its weight, against 0.4 % for polyester), so the fill stays dry to the touch, and the natural crimp of the fibre springs back each morning rather than matting. A wool pillow that is aired in the sun now and then keeps its shape for decades, which is not something anyone says about a foam or polyester one. The cotton cover comes off and goes in the washing machine; the fill is aired, not washed.

The other benefit of wool fill is warmth without heat. It is warm to the cheek on a frosty morning in a way a plastic bladder never is, but it does not trap heat against your face in summer, for the same moisture-buffering reason. The mechanism is the same as for the rest of the wool sleep system and is explained in How Wool Keeps You Warm.

The home wool pillow

Everything above applies at home, where the pillow is the wettest thing in the bed for the same reason. The wool-filled bed pillow is the camp pillow’s full-size relative: wool fill in an organic cotton cover, dense enough to shape, and it stays put rather than sliding. Our founder keeps a small firm pillow for back sleeping and folds it or stacks a second for side sleeping, exactly as on the trail; a firm, shapeable pillow is a firm, shapeable pillow wherever it is. If you are moving the bed towards wool one piece at a time, the pillow is the second thing to change after the sheet, and the reasoning is in Natural Fibers and Sleep.

Which camp pillow to bring

• Thru-hike or fastpack: stuff sack of clothes. Learn the neck-roll technique and you will not miss a pillow.
• Weekend backpacking: wool camp pillow if comfort is the point of the trip; stuff sack if you are chasing miles. Many people carry the wool pillow and put the clothes bag under it for side-sleeping height.
• Car camping, canoe trips, basecamp, cabins: wool camp pillow, or bring the home pillow. Weight does not matter and the difference in sleep does.
• Inflatable: the right choice only when packed size is everything and you sleep on your back on a soft pad. On a firm pad, and for side sleepers, it is the worst of the three.

The pillow is one of four pieces (bag, pad, liner, pillow) that only work properly as a set. How they fit together, by season, is in How to Sleep Outdoors Naturally; the pad it sits on is compared with foam and inflatables in Wool Sleeping Pad vs Foam and Inflatable Pads.
