Q. How does your Wool Sleeping Bag and Sleeping Felt compare with down and synthetic fill bags?
For weight and volume during dry weather, wool is about the same as synthetic and heavier than down. During damp weather, wool wins out.
We believe there is more to sleeping outdoors than weight, volume and temperature rating. The other factors are:
1—Humidity Factor (same as Wind Chill Factor only this applies to humidity)
2—Breathability (ability to ventilate and not feel stuffy and clammy)
3—Sleep Quality (ability to go through all four sleep stages easily)
4—Comfort (perceived softness and warmth)
5—Versatility (Works through a wide range of temperature and weather extremes)
6—Health and vitality (you wake up feeling great with a ton of energy)
7—Ecological impact (renewable resource that doesn’t pollute or exploit animals)
When considering these factors, wool wins in all counts. What wool lacks in weight and volume advantages (compared to down) it makes up in all the other areas. Continue reading to find out why wool is worth its weight.
Is the Sleeping Felt itchy since the felt is directly exposed?
1—Different people have different sensitivities. Some people find it itchy at first but most people find the roughness of the raw wool is not noticeably uncomfortable. In fact there is a soft feel because the lanolin is still in the wool. Lanolin is known as a healing oil and is partly what makes the wool wick moisture.
For cold and wet weather to get the maximum temperature performance—use the raw wool felt on the inside and cotton shell layer on outside.
If you don’t like the felt layer near your skin you can wear your base layer (pajamas) or use a Merino Liner sold separately.
2—For milder and dryer weather when you don’t need the maximum temperature performance but want a good night’s sleep—use the cotton liner on the inside and expose the wool felt to the outside.
This creates a soft and breathable surface that is comfortable against the skin and works well in dry weather when moisture is not an issue.
3—For non-backpacking camping use the Sleeping Felt as a pad to sleep on top of. It is best placed on top of a closed cell foam pad for protection from ground moisture. For this use, fold the felt in half so it has maximum thickness and cotton is on the outside.
Can I use the Sleeping Felt while hiking the Appalachian Trail?
Yes. The Sleeping Felt is about the average temp. rating for a through hike on the A.T. It is very well suited to the moist, wet conditions found in that climate.
You can extend the range of the current 40 degree rating by wearing more layers of clothing while sleeping. You can also buy a Naked Felt (felt alone without the backing) which adds 2 more pounds of weight to take you down to 5 degrees. (For a total of about 5.5 lbs). Note: To bring this bag to its maximum temperature ability, use the ‘Breathing-inside-the-bag-technique’.
What is the Breathing-Inside-the-Bag-Technique?
Crawl into the bag. When back sleeping do this by pulling the knees up. When side sleeping just scoot down into the bag and pull the top down over your head so you are completely covered by your Felt or Bag. Your breath will warm the bag eventually to 10 degrees warmer than you were before. It does this because you are conserving the heat you would normally loose from your breathing. Your body doesn’t need to constantly warm the air because the air is already warm. It is not an instant effect. It may take 30 minutes or more to achieve this temperature.
Advantages (in cold weather where this applies):
1—Besides keeping you warmer, your body does not need to heat the air you are breathing in (as much). This preserves cellular energy so your body can use that energy to keep you warmer.
2—You are getting more efficiency out of the weight you are carrying, using every available resource to make it extend it’s maximum range.
3—You will sleep deeper because when you breath back in the CO2 from your breath it 1–Reduces serotonin , 2–Increases melatonin, 3–Reduces stress response and inflammation and 4–Gives your metabolism an extra boost. This can have an effect of deep delta sleep and the accompanying feelings of euphoria. Also breathing the moist air from your breath has another relaxing effect which further hydrates your body.
4–This works as well to protect yourself from mosquitoes and pesky insects.
Doesn’t the moisture from your breath make it damp and thus colder inside the bag or felt?
No. It would in a down bag or synthetic fill bag but not in a wool bag. The reason is that wool naturally wicks moisture away from the heat source of your body. So the moisture created there will constantly flow and migrate out of the bag and this keeps the wool dry next to your skin. Wool is designed to do this to keep the sheep at the right temperature and it works even when not on the sheep.
Remember the breathing inside the bag technique to bring you down an extra 10 Degrees F.
How much of a difference does the Merino Liner vs. Cotton Liner make?
The Merino Liner is the ultimate choice especially for wet/humid climates and costs more. The Bag with the Cotton Liner costs less and weighs less (about 10 ounces lighter). It works fine in most conditions but is not the liner of choice for humid/moist conditions.
What kind of sleeping pad do you recommend?
For backpacking an every day closed cell foam pad seems to work the best. For other camping you can use a wool felt as the pad. Folded in half the Sleeping Felt will give you 1/2 of breathable cushion underneath. Use the fabric side on the outside and you will not have the scratchy wool directly exposed.
Does this work in a hammock?
Yes the quilt design works well in a hammock making it easy to get into and out of the bag.
Why do you use cotton on the outside shell? Isn’t cotton moisture absorbent?
We use cotton because it provides the necessary wind protection and does not hamper the ventilation or breathability. The cotton fabric is thin and light (5 ounce) with a high thread count (240) so it dries quickly.
Our sleeping bag is designed to help you sleep closer to nature. It has everything you need to stay warm and dry without zipping yourself inside a closed tent. This way you can enjoy nights under the open sky even in in fog and dew and sleep under a tarp in rainy weather so you can experience nature in a more direct way.
What is my best choice for backpacking and bicycle touring camping?
If temperatures are falling around 40 degrees the Felt. For lower temperatures get the 3 Season Bag with a Merino Liner.
For multi-season year-round-use, get both a Felt and a 3 Season Bag.
In extreme cold you can link them together to extend the temperature range to about -10 Farenheight.
Can you make custom sizes?:
Yes. Call us for a price quote.
How small does the Felt and 3 Season Bag stuff/compress down to?
The Felt is approximately 11″ diamter by 10″ long.
The Three Season Bag is approximately 11” diameter by 12” long.
How much does it weigh?
3 Season Bag (approximate weights):
How long do they last?
The Lucky Sheep™ Wool Sleeping Bags and Felts are built to last a lifetime. Wool actually gets stronger with age due to microfilaments creating stronger bonds. Wool is hypo-allergenic and repels dust mites, fleas, mold and this further helps the longevity.
Can I wash it?
You can wash it by hand in a bathtub. Directions are provided on the website. But the best care is to air in the sun and even rain which has a natural anti-septic effect and keeps your wool sleeping item fresh and clean with very little effort.
What is insensible perspiration and why should I care?
It is the moisture your body releases that you cannot perceive. It is not sweat. We
Why do you have so many choices and variations? It seems hard to choose the right bag.
We have a modular system. You can mix and match depending on your needs, goals, camping style and type, and climate/season. You can use the Felt system alone using one or more Felts connected together or you can mix and match Felts with the Three Season Bag. Call us if you would like help tweaking your selection.
Why did wool die out if it is so good?
Synthetic fabrics were promoted as the new best thing as corporations competed in the textile industry starting in the 1930s. A big propaganda campaign pushed natural fibers including wool out of the market until they almost completely died out. A resurgence in health and organic clothing and bedding has brought wool and natural fibers back on the map.
What kind of returns policy and warrenty do you have?
You have three weeks to try it out and return your Lucky Sheep™ product in new condition. Materials and workmanship are guaranteed against defects under normal use and wear.
Why do you use a Quilt design instead of the standard Mummy Bag?
The Quilt Design makes more sense. It works better. You can get in and out with ease and you can wrap yourself tightly or loosely adjusting to the temperature changes during your adventure. You can also use the bag indoors on your bed because it unzips completely flat and symmetrical.
Why couldn’t I just use a wool blanket to get the same effect?
Because wool batting and wool felt have more insulating ability than a woven blanket. A blanket is not nearly as warm, and weighs a lot more.
