BMW Spinsack NANO medium stuff sack

The Bozeman Mountain Works (BMW) SpinSack NANO UL medium stuff sack is everything I was hoping it would be - SUL/UL, sturdy, and functional for my uses.

I feel very lucky to have this UL, or even better SUL stuff, sack. I have been dodging using stuff sacks because of the goal of getting a 2 - 3 day pack, total weight w/ food under 10 lbs.

Yet, stuff sacks are invaluable for helping to protect gear from abrasion, moisture, dirt, etc. They also help me pack items in a more balanced and "tight" manner conserving pack space. Therefore, I was very interested in trying out the BMW SpinSack NANO medium size stuff sack for my sleeping bag + BMW NANO bivy sack sleep system.

The simple answer to my concerns was: there are none after using it. (Photos below.)

The sack is precisely what is described on the BPL Gear Shop web page at:

http://www.backpackinglight.com/cgi-bin/backpackinglight/spinsack_nano_medium.html

"FEATURES

Ultralight: Compare these to standard silnylon stuff sack from other manufacturers, which are typically up to 1.5 oz at this size
Drawcord: Spectra
Toggle: Mini-toggle (0.25" x 0.875" / 0.6 cm x 2.2 cm)

SPECIFICATIONS

Dimensions: 12" length x 7" diameter - (30 cm x 18 cm)
Volume: 500 ci (8.2 L)
Weight: 0.295 oz (8.4 grams) *** nearly 40% lighter than SpinSack LITE Stuff Sacks"

The seams are well done, under pressure they do not spread or start to separate when the NANO stuff sack contains a 32 F Mountain Hardwear Phantom down bag, size regular, and a Bozeman Mountain Works Vapr NANO bivy sack, size regular.

What makes this stuff sack a real 5 is the attention to detail in design and concept leading to an SUL/UL stuff sack with a choke collar + underlying material flap to seal out dirt, moisture, etc. A stopper on the choke cord, and the real extra thoughtful feature of a pull loop at the bottom, as shown here:

Even if this sack seems pricey, it is worth it when I consider that without it I can damage or ruin a far more expensive sleeping bag and/or bivy sack by abrasion in a pack, moisture or dirt, spills, etc. getting to the sleeping bag or bivy while in or out of the pack.

So this stuff sack is a 5 because of workmanship and ultra- or super-ultra light weight, and it has all the features of much heavier and still expensive alternative stuff sacks.
