Patagonia Micro Puff vs. Bozeman Cocoon?

Thomas: we do our best to make it a policy not to review products that we also make/sell, in order to keep conflicts of interest to a minimum.

The main differences between the two are: Cocoon has a slightly lighter insulation, but loft may actually be closer to the Micro Puff because of the quilting technique, the Cocoon uses Pertex Quantum for the shell and lining, and the Cocoon is a few oz’s lighter.

I’ve worn the Micro Puff. It’s a great option as well.

I am curious, just how much loft does the Cocoon jacket have?

Polarguard has a natural crimp to the fiber, so loft is variable, and can only really be estimated as an “effective” loft. In addition, this effective or average loft is going to be a function of the manufacturing technique, quilting pattern, method of storage, etc etc.

The Cocoon measures out at 0.5 to 0.8 (point wise measurements, depending on location).

Measurement of effective loft, using the techniques developed by Alan Dixon for loft measurement, originally published in an earlier down jacket review at BPL (see the About Measuring Down Loft section in this article from the archives), and which were used in the recent high loft insulating jacket review, the Cocoon’s loft is conservatively measured at around 0.625 (5/8″).

In the Micropuff review the loft is stated as:

• Loft 0.53 in (1.35 cm)

Here RJ states the Cocoon loft as a conservative .625.

Quite a victory for the Cocoon !

I have both & each has its +’s & -‘s. Micropuff seems warmer but that may be due to its hand pockets, but its fabric has developed small thread “runs” after the 1st use (mine is the full-zip and its heavier, of course. It will be my “winter” choice.
The Cacoon has nice fabric but when you put it on, the sleve liner sticks out of the hand holes & has to be pulled back in –also the chest pocket seam broke & I had to re-stitch it. I’ll use the Cacoon for 3-season use because its so light. I used both in my 30 degree bag when it was zero outside & was warm. The Patagonia Micropuff pants are a terrible fit –way too big even in large, so I sent them back & will wait for a 3-season insulated bottom like the MontBell Thermawrap Pant due out in the fall of 2005 for all 4 seasons (hopefully, rather than packing thermal underware). I feel full side zipps in winter pants are a must due to large boots/crampons, etc if I stop for lunch & want warmth without removing my crampons or boots.
