I can do lunges
Very lightweight. I think they run a tad on the small side, but not by much. I bought this for kayak fishing where my previously purchased swim tights will fit perfectly underneath. The same connection points apply. I’ll try them tomorrow.

Needs reworking, but great concept
I received this suit, and the inner liner fit great. The size of the outer shorts was not just mismatched, but the connection was inadequate. They were set up in a way that basically they would always be low riding when wet, with no available way to tighten adequately.
I would strongly prefer to have a sewn-in liner to the versatility of detachable shorts. That would make these the most comfortable and nice looking suit I have found. Please consider updating the model.
9 inch inseam is great. Colors were great. Liner was great. I liked it well enough I almost figured out how to sew so I could fix them, but that was a daunting task for me, so I ended up returning.

Less than pleased
I bought one, and then a second pair because I thought these were perfect for me. Unfortunately, while the inner liner fits fine, the trunks themselves are just a tag big in the waist and the side velcro adjustors simply do too little, especially when swimming in the waves of an ocean. The trunks kept falling down. I tried to insert a shoelace since virtually all of my other swim suits have strings to keep the waist tight, but this is not possible because of a midline seam. There should have been a tie to keep them snug. I will only use these in a limited fashion and never when in an ocean.

Size L way too big
the waist of the trunks is way too wide for 34" width, although the underneath tights width is perfect.
Returned the product and purhased size M instead, where the trunks waist is perfect for 34" waist but they are too short at the crouch (naturally suitable for size 30" - 32"). Of course the tights are way too small.
Thus, the only solution would be to readjust the Size L waist

Fit is off
I agree with many of the other reviewers about the fit of these trunks. I’m a very satisfied Coolibar customer, but in this case I knew immediately that something wasn’t right. The inner liner fits just fine, but the outside outer shorts are way too big, even though other Coolibar products have always fit well in my size (medium). You can use the tie to help secure the waste, but the predictable effect is bunching below the waste. Not sure what to do with these. I’ll probably just put them away and forget about them. Unfortunate.

I want to love them but the sizing is just wrong
I want to love these as they are very nice. I like the separate liner, look and feel of these but the sizing just isn't right as the shorts themselves sizing doesn't match the liner sizing.
Even though I'm a large by measurement in my experience trunks are always big and baggy so I typically purchase mediums. I originally did that and the outer short size was perfect in a medium, but the liner was way too tight. I returned them and bought a large. Now the liner is perfect and the shorts are too large. Just a really poor inconsistent fit. Honestly I want these, but unless I had the medium outer short and the large liner it just doesn't work.
Separately for the premium these are why do you charge a return mailing fee. That is crazy especially when the sizing is off and no happy middle.

Good product but does not fit all around
The inside trunks fit good however, the outside trunks are way too big.
