Gday,

heading to Japan next week for a 50 day hike, and I’ve got a little bit of a problem…

Night temps will start @ 70F, and at the end of my adventure be about 50F.

my sleep system WAS going to be; OR Alpine Bivy, TAR Xtherm airpad, HammockGear Burrow 20 quilt, and a shitty little air pillow that I hate with the power of a million suns.

Problem #1) I had big issue with the quilt. The down was shifting so much that it’s unusable. HG customer service has been excellent, but postage delays mean I need to get something else.

Problem #2) the damn pillow seems to be airpad-repellent. Within 3 nano seconds of resting my head on it, it’s gone.. teleported to its final resting place in the empty space between the top of the airpad and the top of the bivy. All bloody night I’m tossing and turning, trying to find it, just to get a little bit of comfort. I generally end up sleeping on my arm (I’m a side sleeper).

I don’t want to sound like a total twat – the bivy and the xtherm are excellent!

So… I thought about buying a sleeping bag liner with a pillow insert. S2S has a range. I’m also trying new pillows, but I think they’ll all have the same fly-off-the-airpad issue. The liner will hopefully fix this.

That then got me thinking.. will bivy+xtherm+liner+clothes be warm enough for 50F? I’m only taking a light-weight down jacket (uniqlo).

 

So.. enough small talk.. here are some questions;

  1. sleeping in a liner+down jacket for the last ~30 days (at a guess). Too stinky? Too hard to clean? (the down jacket, that is)
  2. LocusGear Nxy quilt vs Montbell blanket? Both are available in Japan if I get too cold. Shipping is quite fast, and doable. Nxy is about $100 more expensive. I could spend that on more ramen!
  3. pillows on airpads. Is them flying off a common problem? Any other solutions, other than liner with pillow pocket?

As always, thanks :)

XTherm and a 20° quilt sound really hot for the temps you are expecting.

FWIW I’ve got 60+ nights in my 20° Burrow down to the high 20°s and I’ve always been warm on a women’s NeoAir or in a hammock with a Phoenix UQ.

I use an Exped pillow or ZPacks pillow stuff sack and neither scoots out from under my head.

As a major Montbell fanboy I’ve been tempted by that down throw but it’s very narrow at 44″ wide and spendy at $189. I think I’d be better off with a 50° HG or EE sewn-through quilt for $10 more.

EE and HG aren’t an option. I leave Australia for Japan in 6 day’s time. If I need something warmer my only options are LocusGear, Montbell (stores all over Japan), or some other sleeping bag from a camping shop there.

Regarding your pillow, the monkey pillow case works well.  However, if you can’t get one in time, a t shirt works as well…pull it over the end of your sleeping pad with the pillow inside (I learned this trick here at BPL…thought I’d pass it on!)

just get a 30-40F BAG … you can easily use it as a quilt at ~50-60F …. and then close it should it get colder

theres many around …. MB, MH, marmot, rab, etc … you might even be able to find a sale

personally i use a WM highlite for 40F+

condensation might be an issue with the bivy especially in a coastal environment … if it is simply put yr fleece on the outside of the bags footbox … you can also carry a cheap light cotton bedsheet and put it over yr bag (or use a liner OVER the bag)

For those temps, the $20 down throw from Costco should be fine. They’re back in stock at my store here in Georgia so probably a lot of other places as well.

Rob, the Monkey Pillow is great but I can’t find them anymore. They aren’t on Etsy as of now and  Wallace’s blog hasn’t had an update in 2 years. Do you know where to connect with them?

Unfortunately I don’t.  I had no idea they were no longer on Etsy.

Well, I decided to bite the bullet and get the Nxy quilt. I’d rather be too warm than too cold, and some of the nights I’ll be sleeping near mountain tops over 1000m.

Thanks for the shirt-over-the-airpad tip. I’ll try that out tonight!

i just noticed the nyx quilt you posted is primaloft one

this insulation, while perhaps the warmest synthetic at one time, also loses its loft fairly quickly if constantly compressed … its a short staple insulation

for quilts/bags climashield (apex) is the perhaps the one that last the longest

I think you should have waited until you got to Japan to gear up. MontBell Japan stores have an awesome selection of goods (far more than their US site shows) as do other the outdoor retailers in Tokyo. And the “silver week” holiday sales underway when you are scheduled to arrive can pretty good. I lived there for 24yrs, what is your planned route?

I feel you on the pillow. I use 4 small 1″ squares of adhesive pieces of Velcro. You make sure to put the soft/loop pieces on the pad and the hard/hook side on the pillow. The reason is to prevent your bag or quilt from abrasion. I’ve been doing this for 2 years with no problems and my pillow in place all night. I use a neoair xlite and a Big Sky Dreamsleeper but it should work most combos.

Where about in Japan?

I take it not too high elevation taking from your temp range.

Condensation is often an issue, so I don’t think the synth choice is a bad idea, but agree perhaps shopping here would have made sense. Depending on your timing etc.

Buff or other neck gaiter over the pillow?

The fall rainy season (秋雨前線) is starting now, which often lasts a couple of weeks. Expect, or be prepared for, wet weather.  ( I love rain, except on Alpine technical trail, and can’t wait).

Have fun.
