If your green travel journeys find you in non-traditional overnight accommodations where crisp clean sheets may not always be in the cards (think yurts, huts, hostels, or the occasional couch via couch-surfing site), it’s essential to have a high-quality organic sleep sack.
I thought I was getting by just fine hauling around my heavy-duty backpacking mummy bag in all seasons, until I recently tried out Grand Trunk’s Bamboo Sleep Sack.

What is a sleep sack vs sleeping bag liner?
A sleep sack is like a personal, portable set of sleep sheets.
Most sleep sacks are constructed much like a traditional rectangular sleeping bag, but are sized more generously in both length and width.
Some even come in double.
Most are made of thinner cotton or silk (much like a set of sheets), though I’ve seen flannel as well.
Sleep sacks are stored in cinch bags or rolls, or can be folded up in a backpack or suitcase.
You can use this sleep sack as a sleeping bag liner in cold climates, or use it on its own in warmer climates.

Grand Trunk’s Bamboo Sleep Sack
The Grand Trunk Bamboo Sleep Sack is so very soft, I don’t think I can ever go back to cotton.
It’s lightweight, so it would work beautifully in warm climates, but can be paired with a sleeping bag or blanket in colder weather (check prices here).
It’s of course far roomier than my mummy bag and features a nice slit down one side that can be tied back up for easy entry and more space.
Best of all, it has a pillow pocket, so you can insert a pillow, which won’t slip around and disappear during the night.
I took the sleep sack along on a Mt. Hood, Oregon wilderness snowshoe overnight, where we trekked to a rustic hut that was equipped with communal sleeping bags.
I’d need the warmth of the bag, but didn’t relish the idea of sleeping directly where a stranger had the night before, so I wiggled into my sleep sack, then slid into the bag.
The arrangement worked perfectly, and since the bamboo sleep sack is only 16 ounces, I avoided carrying in a heavy bag.
Next I packed the sleep sack for a weekend trip to Portland, OR, where I’d be renting a vacation home room which I wasn’t sure included linens.
Turns out, it did, but I still felt more comfortable using my sleep sack, sandwiched between the sheets and comforter.
Using it with extra covers over me instead of a sleeping bag, I did get a bit tangled up at times, but have I mentioned how soft that bamboo material is?
Totally worth it!
The bamboo viscose material is not only soft, but quite stretchy, and washes easily in a regular washing cycle.
The feel reminds me a little of “t-shirt material” sheets, but better.
Plus, since it’s bamboo, it naturally wicks moisture away from your body.
And of course bamboo is a sustainable, renewable fiber, so you’re doing the planet a favor, too. Nothing synthetic here!
The bamboo sleep sack rolls into its own small cinch sack.
Grand Trunk Goods: Good for Green Travel
We like when companies are good stewards.
There are few on our short list of green companies.
It does my heart good when I find a travel product company that truly gets travel.
You’d be amazed how many don’t!
Not only does Grand Trunk sell eco-friendly travel products that you’d actually use, but their philosophy — that they make products for travel, not trips — tells me that they’re in the “travel as a lifestyle, not a destination” business.
While you’re checking out the sleep sack, take a look at their hammocks, shelters, tents, and hammock compatible sleeping bags!
