Q. How does your Wool Sleeping Bag 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.

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.

Q. Doesn’t the moisture from your breath make it damp and thus colder inside the bag?

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.

Q. 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). We recommend the Merino Liner for most camping and the Cotton Liner for indoor use. The cotton liner would be fine for summer and festival camping.

Q. 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 our Wool Sleeping Felt.

Does this work in a hammock?

Q. Yes the quilt design works well in a hammock making it easy to get into and out of the bag.

Q. 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 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.

Q. What is my best choice for backpacking and bicycle touring camping?

If temperatures are falling around 25 F. get the Rewilder with 2” loft. For maximum warmth get the Rewilder with 3” loft.

Q. How small does the Bag stuff/compress down to?

The Rewilder with 2” loft is approximately 11” diameter x 12”. The Rewilder with 3” loft compresses to approximately 11” diameter by 13” long.

How much does it weigh?

(aproximate weights)

Rewilder 2” Loft

small—3.5 lbs.

medium—4 lbs.

large—4.4 lbs.

Rewilder 3” Loft:

small—4.25 lbs.

medium—4.75 lbs.

large—5.25 lbs.

Q. How long do they last?

The Lucky Sheep™ Wool Sleeping Bags are built to last many years with proper care. Wool batting 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.

Q. 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 release a pint or more per night and wool allows this to release but synthetic fabric does not.

Q. 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 type of pad do we recommend?

When backpacking a closed cell foam pad is good in damp conditions. When at home or car camping, it is nice to place our Wool Felt Sleeping Pad on top of the closed cell foam pad.

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.

Q. Why couldn’t I just use a wool blanket to get the same effect?

Because wool batting has more insulating ability than a woven blanket. A blanket is not nearly as warm, and weighs a lot more.
