I have tried multiple liners and shorts, and as a slightly bigger guy Pearl Izumi just plain FITS. This liner I was concerned about due to the thinner pad, but riding up to 4 hours on it felt great. The mesh uppers are very comfortable and very welcome on hot day. For guys, Pearl Izumi cradles your privates exceptionally well. Highly recommend these.
The chamois in these liners is quite nice. Unless you're wearing some loose fitting jeans however you're still going to look like you have bike shorts under your clothes! No big deal though right! I guess it depends on what you had in mind. I don't mind the slight diaper butt look, but what did bother me was that when I were them under my ABC pants (nod to those who know!) the leg bands were very obvious under my slacks were they were compressing my skin! So I'll keep searching for a pair with a looser leg band. Meanwhile, these will be excellent with shorts for warmercasual commute days or the mountain bike!
What's nice is you can wear your baggies on fun rides with these underneath and still get the functionality and protection of riding shorts. The liner has anti creep material that grips without irritating your thighs or waist to prevent them from ending up where they can crowd your rooster.
Plenty of breathing in the fabric's weave.
I really like these things. They fit great, don't chafe, seem durable and well made. The pad is probably just the right size. Any bigger, it would not fit under my tights as well. I've used them with the thick, fleece-lined winter tights so far, which just by the thickness of the tights offers some padding, so not sure how they would go with summer gear. I've never used liner shorts before, but I'm a total convert now. As a daily commuter, it saves some washing on the tights and just feels a bit more comfy and toasty (again winter riding only so far) having that under layer. I bought a few pairs and think they are great.
These liners are practical for a variety of uses. Under all the layers for cold rides on the fattie bike, under comfortable day clothes for local errands in town, and for a few hours under tights or long shorts for singletrack rides. As others have noted, they launder well and don't get smelly.
These are very well-made shorts. Padding good for shorter outings (say, under 50 mi.). For me (5'11, 170 lbs), they're a little longer than I'd like, and I find them a overly snug on the thighs. I found the comparable Louis Garneau product more to my liking. The LG padding is a bit more substantial, tho' the PI shorts are arguably slightly better made overall.
This is my second pair of Pearl Izumi liner shorts. The first finally wore out after around 3 years of weekly MTB use. Not surprising. Love the comfort these newly purchased liners provide, the fit is great and the chamois stays in shape, just air dry, never put in the dryer. No chafing or rough results to the legs and they stay up without drawstrings. The best part is I can wear whatever mountain biking shorts I choose over them. It's a win win win with this product.
Months ago I bought a pair of the Pearl Izumi liner shorts to try when I found them on sale, the pairs of the competitor's liners that I had been wearing had stretched out of shape and gotten holes in them. I learned quickly the Pearl Izumi liners are a great improvement-the fabric breathes, that is transfers moisture away from the body, and never develops an odor. So when the Pearl Izumi liners went on sale again and at an even better price, I bought three more pairs. Six of seven days a week I either spin for two hours or road-ride for two to five hours. I always wear liners to prevent chafing and be more comfortable When I am in the saddle for the hours-long periods. They make such a difference for me, and now a riding buddy has tried them and swears by the benefits of an extra layer of padding as well. I've had my three new pairs in my rotation of bike clothes for about five weeks and can attest that they wash well. I like their ribbon loops for hanging them to dry. I recommend these Pearl Izumi liner shorts to those who wear liners, and I suggest those who don't usually wear liners to try a pair for more comfort in the saddle, to avoid chafing, and to have another layer of compression working for you. My pairs all have been true to size.
I've been using the liners as intended-underneath tights, and indoors on my trainer. They're less bulky than good biking shorts (I wear only PI P.R.O.) and adequate for the trainer, and dry more quickly. I bought a pair for my son, and he also likes and uses them.
This liner is adequate for all but really long rides. They fit well with almost any shorts, pants, or tights. The pad is comfortable and the fabric light. Construction seems good and they appear to durable. These are a staple pad for 2-3 hour MTB rides.
These liners certainly add cushioning to your ride but I have found their main use to be keeping my upper legs warm on rides where I'm using summer bibs with leg or knee warmers.
