Alpinestars Bionic Freeride Shorts 4.7 5 38 38
Great product!!! I wear them under my jeans and depending on the cut of jeans can be noticeable. However the protection they provide are definitely worth looking a bit curvy. They run on the tighter side. June 3, 2013
Feel protected Got these to wear under Slider jeans to protect hip bones and tail bone. I'm 5' 10'', 200 lbs, the large fit snug but comfortable. The tail bone armor does start to hurt a bit after about an hour on a cruiser. A small pad to cushion it would help. May try it improvise something but I won't ride without these on because I want the protection. Good product. June 3, 2013
great protection at a resonable cost I wear jeans and wanted something to give me some impact protection. The shorts fit great and are comfortable enough to wear all day. I can't really comment on air flow as usually the bike blocks the crotch area and there isn't much air in that area. The legs openings are a tad tight but you get used to it. The silicone around the legs holds the pants well. The tailbone padding isn't noticeable if you sit on a padded seat. You do feel it when sitting on a hard seat. Sizing, I wear a 36 jean and got the large. Fit is spot on and not tight or loose. I highly recommend these shorts especially if you wear jeans to ride. No reason to end up with a hip injury. June 1, 2013
Another forget about it product... First of all thank you to all the reviewers that pointed out that this shorts run a size small. I went a size up when ordering and as most reviewers mentioned the waist fit was correct, but the leg openings are rather on the small size. I have just finished a 1000+ mile trip ranging from forty to nine five degree weather and I never even noticed wearing this shorts. The tailbone protection was not noticeable at all, even sitting on the bike for a three hour non-stop run. They do make me feel a lot safer and fit comfortable under my riding pants. They have broken in nicely and the leg openings have stretched out enough that they fit very well now. A good price for a peace of mind. May 25, 2013
Well made comfortable protection Wearing this under my Dainese textile Air Drake pants. 6' 215lbs, 36"-37" waist and the 2XL fits perfectly....they seem to run a bit small. Don't even think about them when riding. May 20, 2013
Runs small in size but comfortable I chose medium and am 5-9", 170 lb (77kg, 177.5cm). The thighs of the bionic shorts are very tight to the extent that they leave a significant mark in my skin after wearing for a couple of hours. (However, I also play ice hockey, run, cycle, and lift weights--so maybe somewhat my fault). nevertheless, it seems to be an issue for me with the other Italian equipment manufacturers as well. I thought about going up a size, but would risk the short riding up. Maybe the thighs will stretch a little over time. I have not, and hopefully will not, test the protection, but the hard pads should reduce lateral thigh and sacral impact. No protection on anterior thigh, though. The material breathes reasonably well (I ride in Phoenix) but I am not confident the shorts would hold up to frequent machine washing. You can test that if you wish and report back. The shorts are too expensive for me to try, which is the last issue. $$$ for shorts that go underneath your street clothing? Then again, hip and sacral fractures are expensive, too. May 10, 2013
Great Protection with Comfort First let me say that even if you have ordered other Alpinestars protective apparel and you have read their sizing charts you STILL need to order at least one size LARGER. That said, I am an even six feet tall, barefooted, ~180lbs-185lbs, with an inseam of 34 inches and a waist size of 32-34 inches. This puts me at a medium according to Astars. I also wear a size 54Euro (also a medium) in their SP-1 full one-piece leather suit, and it fits amazingly well. I originally ordered a medium based on all of this, despite all the warnings of previous reviews. When I tried them on they were indeed WAY too tight, especially in the crotch and around all the openings but the most at the leg cuffs. They would easily restrict blood flow to your legs in a short about of time. The rear of the waist also rides really low which was uncomfortable and left me wanting to pull them up constantly. I even tried them on under my SP-1 suit. I would like to say that I was afraid they wouldn't fit given the size of the protectors but it wasn't a problem at all, even in the crouching position. Those cuffs are just too tight and the rear was way too low. After doing the exchange (thank goodness I ordered through Revzilla!) and receiving a pair one size larger I was very pleased with the fit and feel. They felt much better under the leathers too when crouching and moving around. The silicone lined cuffs are nice and keep the leg extentions in place, but without pulling hairs. It's nice to finally see such a feature that has been around in cycling shorts for a little while already. I did have a chance to test these really well a few days after receiving them. I wore them for the entire one hour backseat car ride to one of the local ski resorts for a night of skiing after work. The tailbone protector did NOT bother me at all for the whole night, in the car there, riding the lifts, or riding home. I ended up having two really bad crashes that night too, both on the same run. The first was after a jump near the top of the mountain and the second was after catching my ski edge on some ice while trying to catch back up to the group. Both falls were bad enough that either one would have normally sent me limping-it down the mountain and on into the lodge for the rest of the night. Not only was I able to keep going without being in any pain after those back-to-back crashes but I was able to get back on the lift and go at it again. My only complaints are that the rear of the top could still ride a little bit higher and, my only true complaint, is that a 'relief' pocket in the front crotch would be super nice. I don't know why this feature was discontinued. If it did have that, I would have chosen a five star rating. IN SHORT: 1. This is a great product with some stellar protection. 2. Order a size up - at least. 3. Again, ORDER UP A SIZE. 4. Great for any activity where added hip, thigh, and tailbone protection would increase your enjoyment of that activity, i.e. motorcycling (road/track/dirt), mountain biking, snow-sports, etc.) 4. Last, but not least, Revzilla's return/exchange policy rocks! March 21, 2013
Great Confidence, Easy to wear These have worked out pretty well for me. I can wear them under my jeans or my Alpine Stars Over Pants. They can be a little snug in the waist and at the bottom of the leg openings, but not too bad and they will break in over time. They can ride down on you a little bit if you are standing or walking, but if you pull them up and go ride, they stay in place. The tail bone protection I could not even feel while walking and nothing while riding. Go bigger in size, maybe two sizes, they fit small. 38" waist, I got the XXL. 2011 Suzuki GSXR 1000 March 17, 2013

Answer: 
The fit of the Alpinestars Bionic Freeride Shorts is indeed similar to the Alpinestars Comp Pro Shorts. Typically, we recommend using your underwear size as a reference.

Answer: 
More like boxers if you go up in size, but if you try true to fit, then like compression shorts.
I have a 38" waist and went for the XXL and they fit me perfect, even though they are slightly snug, but after one ride they have stretched a bit and I do not even feel them while I ride.

Good question! We contacted Alpinestars and they recommended hand washing with a cleaner that does not use detergent, then air dry. Machine washing and drying may damage the product.

Answer: 
They have wash instructions, but I am spraying them with a fabric freshener between washes, then hand washing and line drying them when they do need need a real wash. If you do machine wash them I would suggest putting them in a load with other large soft times like towels and pants. I would personally avoid machine wash as much as possible though, for both their sake and your machine's sake.

For most synthetic sports clothing, warm to cool water, whatever soap you normally use BUT I rinse twice to ensure I remove all of the soap residue. I prefer to air dry indoors whenever possible. The dryer is hard on gear.

your waist is not a "squishy" area. Stick with your actual pant size unless you are planning to wear more than two layers.

Answer: 
I'm 5'8", weigh 158. 32 pants are a bit large for me. I wear 31 waist when I can get pants in that size. I purchased MEDIUM and they fit fine. The waist/seat was maybe a tad large and the leg opening maybe a tad small, but I wore them for 2 full days at Cornerspin 'roadracing in the dirt' school and they were nearly perfect for me.
