LL Bean's TEK2.5 waterproof/breatheable system?

post #1 of 5
Thread Starter 
I'm considering this rain jacket for my wife:

Does anyone know anything about it? Specifically, I'm wondering whether it's a coating or a membrane/laminate, and how well it works.

(I've tried LL Bean's phone and online help and can't get through.)

Are you using it for rain or for skiing?

conceivably both. it's for my wife. she might use it occasionally for skiing (possibly even XC), but she doesn't go nearly as often as I do at this point (and she has a new insulated Gore-Tex Sportif jacket that I just got her that would work pretty well for skiing.

but it's primary use would be for rain, particularly for hiking and walking.

Single layer Nylon with breathable coating inside

It appears to be single layer Nylon with breathable "membrane" inside. Thus, it would be equivalent to the Marmot Precip jacket (about $100).

Basically, these jackets are Nylon with the "magic" breathable layer ("membrane", ie, Goretext clone) on the inside. This construction is easy to identify because the "magic" stuff is (typically) white and glossy.

More expensive jackets laminate a loose weave Nylon on the inside to protect the "magic" stuff (thus making a "three layer" fabric). The two-layer fabrics are cheaper and lighter but may not hold up quite as well.

The "coating" in "non-breathable" "coated" jackets typically is clear (so the color of the jacket inside is the same as the color outside). In a technical sense, a "membrane" is a "coating". The "membrane" breathable stuff, though, has microscopic holes to let the moisture out. The "standard" coating does not.

thanks, njk. I wonder if the 2.5 means 2.5 layeras, that it has some extra layer inside, perhaps mesh?

the pic. in the link above shows colored linings, rather than a white glossy one. hmmm....

I had thought that Precip was a coating, not a membrane. (but perhaps REI has it wrong in its description: http://www.rei.com/online/store/Prod...t =REI_SEARCH )
