Sports Chalet seems to have a better selection of gear than the typical Sports Authority when it comes to specialty areas like diving, camping, climbing or hiking gear (except boots). It's worth checking if I need something quickly and don't have time to order on-line or trek out to REI in PV.
Prices tend to run to high... especially on some clothing lines. That said, I've seen some good sale/markdown prices on occasion (recently on larger Camelbaks like the Cloudwalker). If you just need the basics, go to the Big 5 sports behind this store near Golds Gym or the Super Walmart up the street... you'll save $$.
