With the cool weather that we have right now I wouldn't worry too much. If you are leaving it out in the summer exposed to the hot sun all day then that could create problems.
i bought one back in march this year but returned it after seeing how thin the plastic was. i even took it out once to see how it handled and i was honestly scared to be in that yak so i returned it, saved more money and bought a ride 115 instead.
Hahaha, I love that saying . . . yeah, I think some of the advice I was reading and receiving was a little hypochondriac in nature. I think I would enjoy fishing from a sit-on more, but considering my current living situation and vehicle and budget sit-ins really suited me better. The yak of my dreams is a Jackson Kilroy, if I ever manage to own one of those badboys I'll treat it like a newborn.
Thanks for the advice guys, as usual this board is invaluable for a bumbling angler.
