I love these. So so comfy. Don’t move at the waist or on your legs. So happy I bought these and will 100% purchase at least one more pair. Fit true to size. Highly recommend!

WHY YOU'LL WANT IT
Meet the upgraded SQUATPROOF Shorts. Designed to sculpt, smooth, and stay put through every workout, these shorts now feature seamless leg openings for an even smoother fit and upgraded silicone grip technology to help prevent slipping and ride-up.
The leopard-print silicone waistband adds a bold touch while keeping everything comfortably locked in without digging. Paired with a supportive 4” high-rise waistband and compressive second-skin feel, these shorts are built to move with confidence whether you're lifting heavy, heading to Pilates, or running errands after class.
No front seam. No constant adjusting.
✨FIT NOTE: These have a more compressive fit than the Bestie Shorts. If you prefer a little more give, we recommend sizing up.

Love the new seamless look!
Love these shorts!!!!! The grips on the inside are seriously next level. I purchased the set for a long road trip and they're so buttery soft. They dont ride up or fall down. They're true to a Large. I wear size 10-11 and they fit great!
I’ve been a huge fan of the ARRO Athletics shorts, so I was excited to try the Onset 2.0 Shorts! I already have the original Bestie Biker Shorts in both the 10” and 6”, and what I love most about ARRO shorts is that they actually stay in place during a workout. No constantly pulling them down, no riding up, and no adjusting them between exercises. The Onset 2.0 Shorts are another win for me! I can move, squat, kick, and workout without worrying about where my shorts are sitting. And honestly, that’s exactly what I want in workout gear! Another ARRO favorite added to the collection.
I think they are nice. They fit well and are comfy. Squat proof ✨️❤️
Hate to give these a bad review but they truly roll up. They also just feel thinner than the original bestie short and don’t have pockets. The bad review isn’t about the pockets, I should have seen that! But they do unfortunately roll up for me so I will be returning.
These shorts are incredible! I am on a mission to upgrade all my shorts to arro shorts. Seen here... me a hot mess and my shorts handling the race with ease. The whole half marathon they didn't move a millimetre and were incredibly comfortable. No hot spots or signs of wear and tear from the long hours of training I have worn them for.
This was my first purchase and I'm i love! 100% better than Lululemon! I did leg day in these shorts and they are 100% squat proof and did not fall down. Love to support a Canadian business. Thank you!
They are just “ok”. I ordered an XL (I’m a large in other brands), and they are still a bit too tight in the thighs. I also don’t like the raw hem and that you can see the silicone hearts because the fabric is single a layer. I’ll wear them, and they stay up like the leggings (which I love) but the thighs still need work, imo.
Love these shorts! I have them in black too, and this pattern is so fun :) compression, but not uncomfortable, and they don’t slide or roll! I’m in a size lrg.
I love these shorts and the design!!! I was a bit hesitant at first as I always buy shorts or pants with a drawstring and wasn't sure how the silicone band on the inside would hold up. Safe to say it worked a treat!!! I love the feel of them and they are so comfy......definatley going to be buying some more!!!
These shorts are high rise and hold in place well at the waist. I find Arro shorts in general are designed for curvier girls, while I have a boxy shape, so I have to order a size up from what I normally wear so that the waistband doesn't cut in too much (however this makes it a bit too loose around the crotch). It would be amazing to see a curvy and regular cut for her line.
Did lots of hiking without issue, shorts didn't ride up my leg 10/10. 5'3 210lbs XL
Love my shorts, don't budge at all while I'm Riding, they fit true to size and I am I love with the print.
I absolutely love these shorts. They are so comfortable. I literally been living in them since they arrived in the mail!!! Like I need 20 million pairs of these cause they’re just freaking amazing. And yes, I got two pairs in the black. I should’ve got two pairs and then leopard print as well cause they’re that good.
I love these shorts! The silicone in the legs and the waist keep these shorts in place. Two sweaty full body workouts so far without issue. The pattern is PERFECT! Note: REALLY check the size chart though. I wish I would've sized up (because I assumed. Womp womp lol)
I’ve been a fan of Arro Athletics for years, ever since they first started out, and it’s been incredible to see the brand grow while staying size-inclusive and supporting local. Their sports bra and bike shorts are super comfortable, stay in place thanks to the grips, and don’t slide during workouts. What I really appreciate is that they don’t sacrifice style or comfort for price — you truly get it all. The only thing I would change is adding a pocket to the shorts and including a silicone grip on the stomach band of the bra for extra hold. Thanks Arro!! For reference I’m a small in my onset bra and medium in shorts
10/10 🤌🏽 Perfect fit, buttery soft! I wear them for coffee runs, to mountain biking and they are literally perfect! The little grippies in the legs are BRILLIANT those suckers stay put!
The material is buttery soft and it doesn’t move. I have been a lulu girl for years, but these may be my new favorite.
The silicone really is so great, I wore them on a substantially long bike ride and didn’t have to adjust anything once! They are quite compressive, so size up if you are unsure, I ordered my exact size based on the sizing guide and I couldn’t even get them on, so for sure size up! especially if you have juicy thighs! I had to exchange my medium for a large, and the legs are still pretty tight, not uncomfortable but snug.
Super comfy short, slightly roll at the cuff for me but I maybe could have sized up. The fabric is unreal comfy!!
Love the fit and design, they stay up very well. What I don’t love is that I am a thick thigh person and the bottoms part of the shorts has a thin hem design that actually cuts into the thigh. What would be better is if the hem line or bottom of the short was flat or longer if that makes sense or just wider so that thick thigh people don’t have to deal with this mid thigh
Perfect sizing using the size chart and so comfortable, will definitely be ordering more pieces!
Comfy and stays put!
Legit best short. Only complaint is id love a pocket
Love these. So comfy!
Sooo soft and comfy only thing I wish it had pockets…
Loved my leopard print onset shorts been waiting for them and was not disappointed!! Always so happy with my purchases quick delivery too excellent service and excellent quality. Thankyou for bringing these shorts back ❤️
I did not find them to be a true 6” inseam. They sat a bit too short compared to my other 6” shirts in various brands. The silicone was good but so hot, I wish there was less of it. Overall they were ok but not my favorite.
Amazing 10/10
Best shorts! Stay put while running, spinning and working out! ♥️
I was searching high and low for a pair of shorts with silicone lining around the waist and legs to keep them securely in place during my day-to-day activities. These are absolutely perfect and stay exactly where they should! I also love that Arro Athletics is based right here on Vancouver Island, so I can proudly support local! 💕 I can’t wait to get my hands on more of their amazing items!
Loving the print, also have the black ones
The onset shorts are great. Just the right length and stay exactly where you want them. The onyx leopard print is beautiful as well.
I appreciate the shorts being updated however, now that they are not digging into the thigh, they do not pass the exercise/roll test. They roll up actually worse now than my lulu aligns. Only great part about these shorts is that they stay in place at the Belly, just not at the thighs. I believe the only option to prevent this is a thicker band of anti slip material on the thighs
Sooo soft and comfy!!
I was worried about the 6” as I prefer 8”. But they are perfect for cycling and with the silicone hearts they don’t ride up like another brand I have. Very comfortable and love the high waist and seamless front. Size medium. 165lb 5’10”
They fit a lot smaller than I expected. I have other leggings in size large but these fit way tighter.
My fav shorts to wear out and about. Wouldnt reccomend sleeping in them tho due to the silicpne atbthe bottom. Just made me a lil uncomfy in my unconsciousness
How can you go wrong with on set?!
