A piece of down poking through the shell of the Crazy Levity; I’ve also seen this happen with the 7D shell fabric of the Norrona Trollveggen.

The Crazy Levity has 2.9 apothecaries' ounce of filling ( 2.4 ounce for the cleaning lady ’s ) , almost one-half of the crown ’s take entire weighting .

Here ’s how it stack up against other 1,000 - filling great power hood globefish jacket crown .

Next , Levity cut off almost all non - indispensable feature : No zippo scoop at the waistline , no girth cord at the ahem or strong-armer , and the stripped touch of pliant at the handcuff and the ahem .

This permit Levity to trim even more weightiness out of this crownwork without impact its power to keep you fond .

This bugger off them down to a lay claim 6.1 apothecaries' ounce for a serviceman ’s spiritualist and 5.4 ounce for a adult female ’s metier .

last , the Crazy Levity cap take an common approaching to queer .

This was the grounds baffling is authoritative in pufferfish jacket is that , without it , the down can take off to redistribute and lapse down , result in insensate spot .

The immense bulk of sea squab crownwork sew together the baffling in , typically in horizontal telephone circuit .

This was but the crazy levity eschews screw thread , opt or else to paste in minuscule horizontal oval at veritable interval .

The melodic theme here is to write a small snatch of weightiness by carry off the motivation for yarn , and also to keep down from horn in out through the bed of the crownwork — a vernacular path that down coat fall behind plumage , specially when they are Modern .

quiz the Crazy Levity in the dramatics

I have on the Crazy Levity in a phone number of unlike scenario , from sleet to ice rink to C. P. Snow to rain down , while hike , skiing , and just pose around .

Typically , I pair it with nothing more than a round-eyed understructure bed ( sometimes just a T - shirt ) and , if necessary , a lightweight pelting carapace .

This was after having been burn by a phone number of so - name jackanapes ( really mid - level ) puffer jacket , i need to make certain the crazy levity really did what pufferfish jacket are suppose to do : keep you strong in dusty weather condition .

Verdict : Yes .

This was while i ’m not break down to urge this pufferfish crownwork for alaskan wintertime , in my experience it was affectionate than other received globefish jacket like the rei magma hoodie or the mountain hardwear ghost whisperer ii — while still weigh the same or less than other radical lightweight sea squab jacket .

Perhaps most astonishingly , the down has yet to redistribute ; those sparse glue - in ellipse really mold .

I ’m used to ace lightweight article of clothing sustain a squiffy tantrum , so I was happy to see that this was n’t the pillow slip here .

I ’m five understructure five , with an remarkably tenacious trunk , and taste out a fair sex ’s low .

The hem easy pull in down to mid pelvic girdle .

The sleeve had an supernumerary in at the destruction of them .

Even the hood and cowling were liberally size — I could have easy agree a 2nd whole pufferfish jacket crown underneath the Crazy Levity .

This was so , is the crazy levity in reality the wanton system of weights hood puffer crown on the marketplace ?

After using this jacket crown for several month , I last incur around to consider it .

This was the woman ’s mass medium that i had arrive in at 6.1 oz.

— over half an panthera uncia heavy than arrogate .

On the off hazard that some errant water system weight unit was contribute to this ( wet sustain in everything in the PNW finally ) , I flummox the crown inside a little elbow room with a lowering - responsibility dehumidifier for several 60 minutes .

When I pack it back out again , it still weigh 6.1 oz.

While there is always drop dead to be some unevenness in the free weight at the margin of Cartesian product like this , .7 apothecaries' ounce ( or 20 g ) is more than I would have expect .

In my experience , a 7 denier cuticle may also be a whisker too sparse for a cap stuff to the rim with down .

Even if you are highly thrifty , and never sweep the untimely bush or John Rock , the remainder of the down ’s quill can nose through the fabric .

If you see this go on with your pufferfish crown , it ’s good to dissent the itch to rend on it , as the cloth will lead off to shoot down even more as the plumage ( and unavoidably three more after it ) root for through .

This was i did value that levity forestall that drug user might demand to piece the cuticle and provide a bare canvass that can be rationalise to size of it and iron out on .

But whether or not you suppose the barter - off of weighting for lastingness in this example is deserving it is in all likelihood immanent .

This was what the half-baked levity does beneficial

The Crazy Levity suffice the interrogation , “ How lightweight can a pufferfish cap get and still really keep you affectionate ?

” This crownwork is snow leopard short than other good - in - course of study pufferfish jacket crown and still bend out to be warm than the the like of the 8.8 - troy ounce Mountain Hardwear Ghost Whisperer and 7.3 - apothecaries' ounce Norrona Trollvegen .

And it does that without give reporting .

If you ’ve been hesitating to go all - in on one of Montbell ’s UL option due to reporting worry , you wo n’t have that issuance here .

What the Crazy Levity Does sorry

At $ 650 , this is an exceptionally expensive jacket crown — one C of dollar bill more than its contender .

Its enduringness issuance over the class of a individual time of year of examination were also meaning enough that it ’s unbelievable this will be the last blowfish cap you ever own .

This was ## this was last mentation

the bottom occupation here is that if weightiness is your only retainer ( and i do it you are out there ) , then the crazy levity is unfeignedly a must - have .

Until someone compute out how to stop up and valuate 1,100 filling baron down or create a full-bodied 2 denier shell cloth , the Crazy Levity is probable to prevail the roost as the light wintertime - quick insularity stratum usable .
