Gear Shakedown: Mountain Laurel Design SPIRIT 28 Quilt

IMG_0216Last week, Groucho and I tested our new quilts for the PCT. I recently upgraded to a 28 degree, “regular” size spirit quilt from Mountain Laurel Designs.

I love quilts. Or at least I love the idea of quilts.

A backpacking quilt is basically a sleeping bag with no back. The insulation in the back of a traditional bag is compressed as you sleep, compromising it’s insulating properties. This is more pronounced over time, as all insulation eventually loses it’s insulating loft after repeated compression, and on a thru hike happens for 150 days straight or so… So you end up with extra weight an no extra warmth.

The MLD SPIRIT quilt is a shell of lightweight black ripstop nylon filled with Climashield Apexa insulation. The bottom of the quilt has a cinchable elastic base, velcro closure and snaps which form a temporary toe box, keeping the feet toasty with a small breeze blocking pillow – the quilt can also be used fully open during warmer weather, as a flat blanket. The SPIRIT comes with a nylon ‘waist’ belt (one elastic, one nylon – choose based on your preference) which keeps the edges of the quilt tucked – a handy feature. The neck opening is cinchable with a snap closure, allowing adjustable thermal regulation, and also allowing you to wear the SPIRIT as a camp cape (see photo.).

For my SOBO AT I ordered a 28 degree bag. I was totally convinced I ordered a 28 degree bag. I realized I actually a 38 degree bag while looking at my old order receipt. Ha ha ha. No wonder I was sleeping cold…

I found the 38 degree quilt worked great when it was warm. Once the temperature got to the 30’s I paired it with a liner which kept it fairly comfortable, especially as I modified combinations of base layer, puffer and wind pants and jacket. In November on the AT we had a month of 20 degree nights with at least one sub zero. These nights not ‘comfortable.’ Folks say you can wear more clothes to make a 3-season bag work in the winter… in this case each night I wore my hiking dress, two base layer tops and bottoms, a fleece hoody, puffer, silk balaclava, wool hat, XL fleece hat, wool socks fleece booties gloves liners and fleece mittens. EVERYTHING I had.

I didn’t die AND as a bonus, I kept all my toes. But the gram-counter in me thought there must be a better way, weight wise and comfort wise to stay alive…

For my Southbound PCT hike, I’m starting with cold weather in the north, then encountering 14,000 foot peaks, and early fall desert nights. Sleeping at below 20 degrees is unlikely tho, so I aim for a system comfortable to 25 degrees. I thought a 10 degree upgrade might do the trick, so in February I ordered a 28 degree SPIRIT quilt from Mountain Laurel designs.

MLD can take up to 8 weeks to deliver in peak season. They’re a small shop, so I ordered early.

We hiked up to Goat Lake (elevation 3200) in early April, the pm forecast predicting 30 degree weather. Perfect. I slept in my hiking dress, lightweight base layer, fleece booties and hat, puffy jacket, and the new 5oz fleece smock I jerry-rigged from a goodwill fleece sweatshirt (more on that later). So at least half of the clothes I needed to sleep in with the 38 degree bag.

And I was super comfortable. In fact, I was the warmest I’ve slept outside. I felt heat radiating from my core. I took off my gloves. And I’m psyched to say I stayed that way all night, even when we woke up 10 hours later to 6 inches of snow. I actually slept and entire night without doing sit ups.

Hooray.
