Ex-Officio Give-N-Go Briefs Review

Most of us (males) want to wear something under our trousers, but what? Ordinary cotton underpants have several disadvantages: the waist band often conflicts with the hip-belt on the pack, and when they get wet they can take a very long time to dry. The Ex-Officio Give-N-Go Briefs largely solve those two problems.


Overall Rating: Recommended

They are tall enough at the waist to avoid conflict with a hip-belt, and they dry very quickly. Even in high summer they don't seem too hot and sweaty, and they do last a long time.
*Addendum 10/19/10: Author notes that Highly Recommended would not be inappropriate. However, BPL does not change ratings once posted.

Ex-Officio Give-N-Go Briefs Review - 1
Ex-Officio Give-N-Go Briefs.

I should start by explaining that the photo here is a stock photo from Ex-Officio. My arms are not that hairy. OK.

Ex-Officio make two similar models of briefs: the Briefs shown here and some Sport Briefs. The latter are shorter in the waist, but otherwise identical as far as I can see. I will focus on the Briefs because I find them much better for walking.

Incidentally, Ex-Officio actually call them "Brief," in the singular. This is the same as talking about "trouser" - I can see the logic, but I can't do it.

The company claims that the fabric "air-dries within hours" and is "extremely breathable, moisture-wicking, odor resistant finish." I can confirm the fast drying bit. I would say 'fairly breathable' as they do get just a little sweaty during a hot Sydney summer day of 35 C and 80% RH - but so does the rest of me. I can neither confirm nor deny the 'odor-resistant' bit.

Frankly, the fabric alone is not enough to justify them. But look at the photo here of a range of (Australian) underpants. On the right you can see the Ex-Officio ones compared to two other sorts. There is a big difference in the bulk of the waistbands. On the left we have some (Australian) underpants with similar flat waist bands - but look at how the elastic has curled up during use. The Ex-Officio waist band does not curl up.

Ex-Officio Give-N-Go Briefs Review - 2
Comparing waistbands.

The third feature I like is the design. The Briefs are taller in the waist region than many other (Australian) underpants. But the other ones seem to fight many hipbelts, getting either pushed down (most often) or pulled up. Neither is satisfactory. The waist region of the Ex-Officio Briefs is flat enough that they seem to stay nicely in position on my waist despite the movement of the hipbelt.

Field Testing

Ex-Officio Give-N-Go Briefs Review - 3
Drying socks on the pack.

These Ex-Officio Briefs have been my choice for a three-month long walk through France in 2007 and a two-month long high-altitude walk through Switzerland in 2009. They have also been used for pretty well all my other walks in Australia in that time - walks typically under seven days, but up to nine or ten days occasionally.

In Australia I usually don't bother with a spare pair, so maybe the odor-resistant bit has some truth to it. But in Europe we often wash our socks and underwear every few days - depending on opportunity. Sometimes it took a couple of days for our wool socks to dry properly, but the Ex-Officio Briefs seemed to dry within a few hours in the sun - strung across our packs.

I should add that the pair of Briefs I took to France in 2007 also went to Switzerland in 2009 and are still in current use. To say 'long-life' seems appropriate.

May seem to be a trivial matter, sort of scarping the bottom of the barrel , however wet underpants can be a pain in the something or rather.
I switched to those Ex Officio unmentionables after a trek when I could not get my lycra stuff to dry overnight and even after 2 days ( it rained a lot) . Had to wear them damp to dry them , but of course they were damp again with sweat in the afternoon.
Now I have a happy bottom.

Many years ago a few of us cross-sport type took to wearing triathalon bib bicycle shorts as underwear with over shorts liners removed. We didn't have to deal with where your belt and shorts interferred. I just wish somebody would make a pair with more durable fabric. I loved my old system until they wore out!

I am normally a 'boxer' kind of guy and own a pair of the Give-N-Go Boxer along with other brands of boxers. The Give-N-Go has been my favorite underwear of choice when walking, hiking and backpacking.

Good review Roger. Undies seem mundane until you're 3 days out and getting chafed. Then every step is pain.

For those with thicker thighs looking to prevent the inner thigh chafe, Ex Officio's boxer briefs are made the same way as the give-n-gos but with a little extra coverage. They've held up great for me.

Merino? on 10/13/2010 09:19:04 MDT Print View

I think underwear are really important. Chafing, moisture retention contributing to fungal blues, drying time, lack of odor retention, interference with a pack; all these are important.

I have been using nothing but merino wool for briefs for the last year or so, including the Annapurna Circuit, and find them the best of any underwear I've used. T-shirts are great, too.

Glorious ExOfficio undies! on 10/13/2010 11:14:30 MDT Print View

I know that seem a bit of an overstatement in commenting on underwear, but dang, these ExOfficio undies really do exactly what they claim to do. I used to use a jock as my preferred undergarment but I had these undies in the drawer for use when we travel. Decided to try them outon a hot sweaty overnight in the San Gabriels. I have never been so comfortable. They do in fact breathe and keep you drier and cooler than anything else I have worn. They are supportive. And as has been pointed out dry in few hours time. They are also very durable. I have had the same two pair I have used for a year backpacking for at least 3 years of overseas travel. They look exactly as they did the day I bought them from REI.
I would give these a highly recommended rating!

Has anyone tried comparing the Ex-officio to wool undergarments? I've been tempted by both for normal city wear (no undies seems to work fine in the back country) but don't want to spend the money if there isn't any gain.

EX-OFFICIO BRIEFS on 10/14/2010 00:24:15 MDT Print View

I have been a happy Ex-Offico briefs walker for some years.
Locally (Brisbane Australia) I have advised at least one person who was proud of going COMMANDO (i.e. no u/pants) not to because of the prevalence of ticks & often leeches with dangers therein. I remember one hilarious occasion of Grant calling in at small rural hospital North Queensland with a TICK IN HIS NAVEL after our removal efforts failed. Leeches in the eye are also an interesting scenario which we best solved via salt water then sterile saline solution (now always in our first aid kits for eye injuries so possible in thick scrub).

lower cost option?: Ex Officio Briefs on 10/14/2010 10:05:46 MDT Print View

I've found Boxer briefs to be great for all the same advantages mentioned above.

But Champion brand has worked well for me at about half the cost.

They are light, fit well, are very breathable, the waist band stays flat and they dry quickly.

Last July in New Mexico I put them on wet after washing them (and myself) and they were dry less than an hour later. But I can't say I know that'd work as well in other climates.

Re: Smell? on 10/14/2010 11:56:38 MDT Print View

Must weigh in here. I spend my summers doing research in the West Bank; I take a minimal amount of clothing and whatever goes needs to be comfortable and durable. Based on those two conditions, I decided on Ex Officio boxer briefs last year.

The smell, the mindbending eau-de-vagrant small-children-leave-the-room-and-animals-give-you-censorious-looks SMELL, after just two weeks, was so offensive that I stopped wearing underwear altogether. My colleagues eventually made a joke out of it, but given that in rural Arab culture bad smells are associated with bad omens, it was shaping up to be an actual impediment to my work.

This year, took Icebreaker 150 boxer briefs. No smell. Arguably less chafey. International incident averted. Your mileage may vary, but I am an ex-ex-officio user for life.

merino beats synthetic on 10/14/2010 21:39:48 MDT Print View

I've been using the Icebreaker 150 wt boxer briefs for two years and they honestly can't be beat. They never get the synthetic "wet" feeling, dry uber fast and stay cool when it's hot out. I wore the same pair continuously for two weeks on the CT in 2009 without any problems. I've tried all sorts of synthetics but I don't know how nylon compares. Unless there's something dramatically superior with nylon compared to other synthetics, merino wool is the way to go.

To respond to Matthew:

I have the Ex-Officio boxer briefs as well as some Smartwool boxer briefs. I like them both, but I have to lean towards the merino wool. I wore them for a week straight in August while hiking through Glacier NP, and they were always comfortable, dried quickly, and kept odors at bay. About every other day I would wash them in a creek, wring them out, and put them right back on. They were dry within a half hour.

However, while neither pair shows signs of wear yet, I'm anticipating the Ex-Officio to hold up better.

Maybe I should have given them Highly Recommended instead? Does anyone have experiences which would mitigate against that?

I believe I donated my Ex-Officio Give-N-Go briefs to the local Goodwill, the waistband was awful on me. They chafed me like mad, rubbed me raw in the inner thigh region by days end. I wear a pair of Smartwool Boxer briefs when I wear pants on trips, these are the most comfortable I've found so far. They're swimming hole approved. Typically, I hike in New Balance split running shorts with wicking liners and have no issues.

Ex-Officio - 5-6 years of wearing these now (not continually I hasten to add); great balance of 'don't know they are there' - 'easy to have a pee out off' - 'wash n wear' - all good - durable - they are great.

EX-O waistband on 10/19/2010 16:22:55 MDT Print View

> the waistband was awful on me.

I think the waistband is the weak link on the exo boxer briefs. They rise too high and seem a bit uncomfortable after a long day.

Thus, I fold the waistband down onto the brief. Problems solved, at least for me.

BTW, based on the discussions I ordered a $45.00 (gulp) pair of the Smartwool boxer briefs for experimental purposes. ;-)

I'll let ya'll know how things are hangin' after I wear them for a weekender this weekend.

I'm a boxers kind of guy but have to say I love wearing the ex-oficio boxer-briefs. I've since bought a pair of their boxers (accidental, thought it was boxer briefs) and another boxer-brief. I prefer the box-briefs to the regular boxers.

I don't have any smell issues with mine and generally wash them every other day or so. They feel great, protect against chafing (which actually has never been too much of problem) and are probably the coolest underwear next to cotton out here in the desert.

I'll also say the ladies seem to highly approve of them as well; they love seeing the glutes.

Oh, yeah. Sooo comfortable and equal to the EXO's on the stink issue. My only concern: their long-term sustainability. My EXO's are rock solid after many uses over many days. The Smartools seem fragile, but I won't be able to evaluate them fairly on that score until I've worn them a bit.
