Alpinestars Switch Drystar Pants 4.4 5 7 7
Excellent Have used these pants for a couple of months in weather ranging from low 40's to driving rain. Kept me warm and dry every time. Get one size up, they run small. March 8, 2016
Good fit and comfortable I like the leg extension system, adjustable knee protection feature and the slim fit. Watch sizing as there is no waist adjustment other than wearing a belt if they are a bit too big. The material seems light weight so I'm not sure how the slide test would go. overall a good product and easy international purchase, thanks July 19, 2014
Good pants for the price I would recommend these pants, even if they're not perfect. Pros: Very warm -- have kept my legs warm down into the 20s on the highway. Comfortable -- even with knee armor and hip pads, they fit great (other than sizing, see below). Nice features -- adjustable pant length is great; I was able to easily adjust knee armor into the correct position; and removable liner snaps in and out in seconds. Cons: Fit -- the sizing chart is off. I wear a 32-33 waist in pants, which equates to a medium on the size chart, but I was nowhere near getting into the medium, and even the large is snug. Definitely order up a size. Material -- very "snowpant" like, which is fine, but they do make a lot of noise walking around, and pick up lint and pet hair like crazy. Not a deal-breaker, because on the bike who cares, but not great off the bike. Cuff zippers -- the zippers at the bottom of the legs, while a nice feature to have, do get caught on the liner so you have to be careful when opening and closing. Overall, a really good pant for the price. I would recommend them, even despite the few relatively small issues. April 7, 2014
I chose these pants because I wanted belt loops and a sleeker fit Pants fit great as long as I don't put any more on! Fit is on smaller side if you want advise. They are as good as I had hoped. Was riding in wind chill of -5 and they were sweet. Only critical comment I could make is the knee and shin pads fit low. They could be 5 cm higher. I'll get plenty of wear out of these on my sports bike, adventure bike and cruiser. Happy riding! June 3, 2013
good pair of pants I bougth this almost one year ago and 15000 miles of use, if its rainy, excellent protección from wind and rain, if you just hang them, the're dry in one hour, the fit is good, but... The ventilation is quite poor so if its a warm day you'll be sweating a lot, and be careful with the hot areas in your bike or you'll have big and nasty holes. Otherwise good product and revzillas service excellent!! November 30, 2012
Great features on these pants. Even though I returned these pants I hope my review will be of help to a future buyer. I am 5'-4", 130lbs. My jeans size is 30W 29L regular fit. Pros: 1) The adjustable pant length is an awesome feature. I was able to adjust the pants to a reasonable length size since most motorcycle pants come in one length. There are three options for the length. either totally remove the zippered cuff or zip it into two different locations at the bottom of the pant. 2) Three positions for knee armor. I was able to place the armor correct for my proportion. 3) The pants material has a good feel to them. 4) Removable thigh warmer. 5) Reflective piping. Cons 1) While the waist and length were a good fit for me, the pant legs have a more of a relaxed fit. The revzilla video states that the pants have a more euro slim fit but I did not find this to be the case when I was wearing them. This baggy feel was the only reason I returned the pants. I prefer a more tailored fit to my gear. 2) While the fabric was nice, I did not feel like the pants would have great abrasion durability in a slide This was not a deal breaker for me but if this was of better quality i might have considered keeping the pants and dealt with the relaxed fit. I would recommend these pants based on the features. Revzilla has a great return policy so they are worth ordering to see if they fit perfectly. October 14, 2012
Great style and fit Good fit feels like wearing a pair of jeans, good warmth down to mid 30's. November 16, 2011
