Staying healthy is critical. Sine qua non.
Wall Street is damp, cold in fall and very cold in winter. Windy area because of New York Bay and the Hudson River.
Rain gear is going to be critical. Problem with rain gear is that heavy suits will cause you to sweat and they're not suitable for sleeping. This ultra-light set is loose, comfy,
Driducks offers a $20 solution. I have used my set for hiking in Upstate New York and Jersey in winter. Perfect. This includes getting caught out in a turnaround blizzard where the Driducks went on over my normal gear -- I was dry and mostly comfortable.
When I bought mine, the alternative brands cost twice to ten times as much as the Driducks for an equivalent pants/jacket sets. I have no idea why.
Mine have been washed in a washing machine several times. Gentle setting. Hang up to dry out. Mine are 5 years old. The jacket sizes out quite large -- their LARGE is a 46-48 chest instead of 42-44. The aim is to fit over a thick sweater. The very loose fit encourages evaporation.
(Checked out eBay. $16 + $7 shipping. Now labelled as "Frogg Toggs DriDucks." The regular Frogg Toggs rainsuit is heavier stuff. The Driducks pair together weigh less than a pound.)
The Frogg Toggs site has this as the DriDucks® Ultra-Lite2™ Rain Suit, starting At: $19.95.
