(Lognomore's 24yo son)
I was using some old bibs and a jacket that wasn't meant for sledding for quite awhile that were really poor, every time we would go sledding I would be wet at the end of the day. Got a pair of the Bomber jackets and pants for my birthday in April so only got a couple rides in with it but they kept me dry on a spring day ride with mixed rain and snow conditions.
I had used my fathers Klim pants on one ride and they felt really stiff compared to the slednecks gear. So in my opinion if your on an extreme budget and using really poor clothing the Slednecks stuff is great, will it keep you as dry as Klim? Probably not but the pants are better than bibs from the 90's and the jacket is better than a goose down parka!
Next season I'll hopefully be able to get a lot of use out of them.
