Enables me to go with a 40-liter pack for four days and three nights in summer.
- Compresses smaller than any bag I've seen
- Good to use as a blanket
- Ultra sil compression sack included
- Storage cube included
- Drawcord with toggle, not zippered, bottom
With this bag, I can get my summer sleep/shelter system down to around 4 1/2 pounds. The bag compressed (15 oz) in its Ultra sil compression sack (blue) on left with a Sea to Summit Ultralight Pillow (2 oz) in the sack also. Next to it is the Marmot Tungsten UL 1 (pole bag, tent body, fly in an ultra sil (yellow) and stake bag (2 lbs 9 oz), and the Nemo Tensor mummy sleeping pad in it's stuff sack (15 oz) on the far right.
I just did a 4-day, 3-night solo backpacking trip in NY with a Gregory Zulu 40 (L) backpack the above setup, a stove, pot, six freeze-dried meals, snacks, changes of clothing, a hydration bladder, a couple of Chute water bottles, a Sawyer Squeeze, a headlamp, other miscellaneous gear, and a pair of camp shoes (New Balance Minimalists, 12 ounces) in the pack's stuff pocket.
The Tr1 is an excellent warm weather optiion. It packs down to a liter and a half. It comes with a compression sack and storage cube. The storage cube zips up for travel, and unzips into a larger sack for storage. The ultra-sil compression sack is water resistant (it is not seam taped), but would cost $20 or more on retail sites. It is size XXXS.
People I've shown this bag compressed are amazed at how small it is.

The bag does have one zipper that runs its length, which when upzipped allows it to be used as a blanket. The bottom has a drawcord, which when cinched removes some of its length; I'd say between 4-6 inches. If you are planning on using it cinched, and you are taller than 5'8", I'd recommend the large. I am 6'1" and own the regular. It is sausage like when fully zipped and cinched. I understood this when purchasing because I wanted lightweight and small packed size. I'll only cinch it, and use it as a half bag (bag pulled up to my chest), on a much colder than predicted nights when I can wear an insulating layer with my arms outside the bag. You can also close the bottom draw cord, zip the Tr1 halfway up, and use the bottom half as a bag and the top half as a blanket/quilt.
The bag is perfect in warm weather, when a blanket is all you need or if you stay in a lodge, hut, cabin and don't want to sleep on the bedding provided.

This is a cost effective and more than adequate light minimal coverage for a quick summer outing in the woods. It is versatile enough for couch surfing relatives over the holidays. It is just wide enough to cover two cozy campers that are not too big in girth on a not chilly summer outing.
- Compacts well
- Foot area can be open or closed
- Not real warm
- Not useful for shoulder seasons
Originally bought for couch surfing relatives, but I found it useful as a comforter on a fall evening too. That opened the door to other uses.
Took it out for a July 6K ft elevation overnight in Sierra Nevadas and it was sufficiently warm in a bivy bag. I added a silk liner and it was okay during a chilly September night in the Cascades. Wife and I used it opened up fully with us in each our own silk liners and in a tent and it kept us comfortable through the night (down to low 30's).
I think our body heat and the silk liners made it work. I would have liked a bit more down in the product to take it down to a few more degrees rather than have to use a heavier quilt. Some modifications may be in order to adapt it to our varied needs and keep it light. The small vol when compressed is great with our small packs.
More clothing rather than more down filling might be the answer, but we have pretty much minimized our clothing to work for most conditions (excluding this sleeping portion). I would buy this again and would modify it as needed (filling +, - some of the zipper as I use open (unzipped) on the top nearly all the time).
