I *love* this harness. I'm 5'9", 140 pounds, 30" waist, enjoy long walks on the beach and I wear a Medium in the Hirundos (and in the Petzl Sama.)

The Hirundos is basically the Petzl Sama on a diet. Take the Sama, chop down the waist and leg loops, skinny out the belay-loop (while still meeting standard climbing harness strength requirements), skinny out the waist-strap and the speed-buckle, ditch the haul loop (but keep the 4 gear loops) and finally, turn the orange up to 11 and make the silver almost sparkly. Yes, "sparkly."

With that said, I love the Hirundos for everything except hour-long hang-dog or belay session. Its light weight and vented means you really won't notice it on during the day. Standard disclaimer applies: If you have really whopping thighs, then the legloops will be tight for the appropriately sized waist. The solution to that? Get the Adjama. :)

Awesome. feather weight. I don't even notice it. Because of an elasticized triangle on the front of the leg loop, I can wear this in the summer sport climbing and over a down suit on 8000ers and still have the same great fit. Working routes can get a bit uncomfortable but that is the price to pay for excellence in nearly all other applications. Definitely in the category of "super gear". Be prepared to receive comments on the "flashy ness" of this harness.

It feels like I'm not wearing a harness at all. It weighs almost nothing at all! It's comfortable to wear whether I'm belaying, climbing, or just sitting down to rest and it's got a great range of motion. Petzl really pulled out all the stops with this one. By measurement I should be on the low half of a Medium but a Small is definitely the way to go for me. If you tend towards the low end of a size you might consider just buying one notch down.

This is an outstanding harness. Petzl didn't cut any corners when they made this harness. It's beefy and lightweight at the same time. I especially like how the strap that holds the belay loop in place is a solid piece of webbing and doesn't come undone.

It's the best harness i've worn yet for sure, and i've sported 7 harnesses so far. It's super-lite and ventilated. Petzl removed all the unimportant junk like leg buckles and created a harness that is just that and nothing more and comfortable in climbing and falls. Don't go setting routes in this harness it's not made for it. I love this harness and you will too.

Perfect sending harness. Definitely not intended for hangs or long belays. The harness also runs true to size, if not a tad small. I'm a 32/33 waist, 6'2 185 and wear a large. I love this baby at Rumney where the crowds are as thick as the flies and the humidity is tangible. Keeps me light and cool with the vented waistbelt and folded nylon loops.

This harness is pretty cool indeed, lightweight, no leg loop, no need to double-back. It's a minimal so not really for trad, but very good for anything else.

This is the best harness I have worn to date. Most comfortable and the best fit around the legs.

Lightweight, sturdy, and comfortable. I recommend this harness to every friend. Has allowed for some of the best days of climbing yet. Mesh covering allows for breathability, and remedies the sweaty thighs so many other harnesses produce. Spend a little more, but you get a harness that will last.

This is my first harness and i am very sastified with it its going to be hard to buy another harness after im finished with this one. It is an excellent buy

I love this harness! It's really the best one I've ever had. It's great for in the gym or outdoors. It's got 4 gear loops for a full set of quickdraws and some gear if you need it. It's super breathable and light. I love the non-adjustable leg loops and the small belay loop. The green color on the black is also a winner. Everyone will compliment you and ask about it!

This is my first harness so I can't comment as to how it compares to others. It is very comfortable and was affordable at $55 and is great for indoor climbing. I am a pretty big guy at 6'5" 200 and the large fits well. The leg loops are perfectly sized.

I was previously wearing a harness (the Metolius Safe Tech Harness, actually) that made me feel like I was in thigh-tourniquet hell whenever I fell, hung, or belayed someone. I got the Hirundos on a friend's suggestion and I'm so stoked - despite the fact that the padding is minimal, it is unbelievably comfortable. Less bulk also means I'm less of a sweaty monkey on hot days. I'm a fairly small gal (5'6, 103lbs) and the XS was perfect, even though this is a men's harness.

I love this harness. It's small, light and very comfortable. Only downside is that can get tangled easily, but that's not much of an issue.
