If this is all you can write, I'll make it a point to NOT read anything by you again, particularly your books. Spam is spam even when sold by another name.
Who am I to say this?
I've been paddleing several thousand days since 1968,(was a whitewater guide for 14 years and still paddle over 100 days per year) and have paddled as cold as minus 8F before dry suits, and have river camped as cold as 0F with an open canoe. I can and do help teach winter canoe camping for free now and wouldn't recommend your advertisement to anyone. Yes, I do recommend some gear that is worth every penny, but not as the focus of an supposed article, and not from any one vendor. When I do recommend gear when asked, I give alternatives over a price range for each item from Walmart (rashgards), tO Kokatat dry suits via eBay, to sponges for free (dead seat cushions from couches on side of road).
I do have a OR Seattle Sombrero which I like for paddleing, but when colder(and windy), I much prefer a Columbia goretex Ear flap hat, a Due North polypropylene fleece Balaclava (my heaviest out of 12 balaclavas), and a Serious Face mask, if I am not wearing a Bomber Beanie skull cap or my mysteryskin hoodie under a helmet. And I carry spares for my friends so no one gets in trouble. Easiest to rescue someone BEFORE they need rescueing and a lot lighter to handle than they would be.
Today that meant 3 pairs of gloves, 4 balacavas, and 2 goretex shells for 5 folks,(in addition to two tow lines, spare carbon fiber paddle, firstaid kit, 4 Chemical handwarmers, and three sets of pogies. Gloves, Pogies, balacavas, and a couple of hats were passed out to folks who found the wind and temperatures not what they heard predicted.
Go back to writing books that I won't buy or recommend.
