- Aug 28, 2006What you'll find at Walmart...
You kinda have to guess at the weights, but it'll come to you.
Search the archives...this topic comes up regularly.
Ripstop simply refers to the pattern of squares in the nylon. The
squares are made from thicker threads that function to...you guessed
it...stop rips before they get too big. Ripstop may or may not have
a treatment on it, frays very easily, and you can easily blow
through it (and so can the wind). It's great for summer hammocks
and isn't water resistant at all.
Durable Water Repellent (DWR) is a treatment added to ripstop nylon
(and other fabrics). It'll usually be shiny, feel slippier, and be
pretty hard to blow through. It'll still fray. Depending on the
treatment, it can be very water resistant or not really resistant at
all. It is breathable, but how breathable depends on the fabric
weight and treatment. Lots of folks prefer DWR for hammocks,
windsuits, stuff sacks, quilt and sleeping bag shells, etc.
Silnylon is very slippery, hardly frays at all when new, and you
can't blow through it. It's not breathable so condensation can be
an issue with certain uses (rain gear, hammocks). It's waterproof
to a certain water pressure depending on fabric weight and
thickness. Sil is good for tarps, stuff sacks, snakeskins, ponchos,
etc. Not many hammock models are made from non-breathable materials
Weights given are usually for the fabric before any treatment is
applied, so 1.1 oz silnylon may actually weigh ~1.3 oz per square
yard. I've found LOTS of 1.9 oz untreated ripstop, quite a bit of
1.1 oz DWR (mostly gray/silver), and a bit of 1.9 oz silnylon.
What kind of HH model do you have? Check the HH website for the
weight of your fly and use that as a basis for your guesses on
Walmart's fabric. Or drop the $4 on a sample pack from owfinc.com
so you'll know for sure.
Sooo...ripstop describes the fabric itself, DWR and sil are
treatments added to the ripstop, and the ladies there will probably
have no idea what the differences are. And don't mind the funny
looks you'll get for being a guy who ACTUALLY shops in the fabric
