I recently bought a Sugoi Helium jacket. It replaces a couple of jackets I’ve had for a long time, neither of which meets my current needs.
The Helium’s perfect for me – lightweight (85gms/3 oz), wind- and water-resistant, and nicely fitted. Though pretty minimalist, it’s got the requisite reflective thingies, a couple of zippered pockets, and rolls up into a tidy, small package. It’ll serve me well for cool weather runs this fall, and will be ideal for the Race to the Stones 100K next summer, where the weather will be variable and, well… English.
(For a good summary of the Helium’s features, check out the short review of an older version of the jacket by Tom Caughlan for iRunFar here.)
I bought the Helium online from Running Free Canada. Not only was it on sale, Running Free’s excellent customer service made the transaction a pleasure. I recommend these folks highly!
