Review: Juicy Plums are fun - My other half Cycles to work every day, 5 days a week and needs to have extra support as he gets Varicous veins and this can cause significant discomfort. So hes been having to wear briefs for years since his diagnosis. So when I heard about Boxer Briefs being a thing (dont judge me, I just thought they were fancy boxers) I decided to have a good look around and find a decent brand that would support him and stop the rubbing that comes with the stresses of cycling daily. After scouring the many, many listings on desertcart, I find the Step One brand of boxer briefs. They look alright and after looking into the description and reviews, seemed to suggest that they would be good for my other half and his specific needs. Now I was on the fence when I looked at the price. I honestly almost left it there at that point, not wanting to effectively waste a considerable amount of money on one pair of these things (I could buy multi-packs in supermarkets for less probably). There was the added risk of my particularly picky Fiancé who is not the easiest to convince to try something new. But, then I read that the company will accept a return on your first purchased pair if you are not happy with them, even if you have worn them! So I take the plunge and buy a pair, which are named Juicy Plums (giggles all round from me, I know I am an immature woman) and after they arrive I present them to HRH letting him know that he should at least try them because he has nothing to lose and that I’ll be able to get my money back if he doesn’t like them. He smirks at them but gives them a try. “They’re comfortable” he says. Good sign, but hes not ridden in them yet, so I tell him to give them a wear while cycling and so he does. Long story short: I have since brought 5 more pairs for him as he likes them so much and may have to consider throwing a lot of old briefs away. As a side note, you can wash these at 30 in your machine and can tumble dry them too. So far I haven’t seen any shrinkage or damage from any of the pairs I have brought. Review: Yes, they are as good as everyone says - A review from someone who has wasted money on other brands that just don’t address the issues men have. So, I’m motivated to share my experience with this brand to hopefully help others! * 3D comfort pouch - This is the number one benefit for me. The elastic provides the support where you need it. It brings the separation needed to deal with sweat and discomfort. Just ran a half marathon yesterday wearing these and they were really comfortable the whole time. No rubbing, pinching, just cradling. Some report problems with the sizing of the pouch, but this is simply a case of selecting the right size. Step one were really helpful in this process. Personally, i went for a small size as i prefer the fitted, ‘everything staying put’ feel. The sizing chart is very helpful. * Material - Really soft and comfortable to wear. No seams in awkward places calling for all-day adjustments * Branding - Prefer the name to other brands that are somewhat less tasteful. That could be just me * Colours available - Just so many to choose from. * Customer service - This has been fantastic. I was hesitant to spend the money, so asked lots of questions. They responded quickly and were very helpful. When I ordered the wrong size, they very helpful. * Cost - Yes, they are more expensive but this is a long-term investment, so buy in bulk and get the discount. * Ultraglyde panels - I ordered trunks due to my thin legs, so this feature was not so important to me however i completely see how this could work very well. I have purchased 12 pairs as a result. I hope this has been helpful to others! ## Features - TRUNKS THAT FEEL INVISIBLE AGAINST YOUR SKIN - game-changing ultra breathable men's boxer trunks that blend style, comfort, and movement for well-fitting men's underwear that's so soft it feels like you're wearing nothing at all - 3D POUCH THAT KEEPS THE BOYS IN PLACE – Big Balls, Small balls - no matter what you're packing these men's boxer shorts not only make your crown jewels look good but surround you and your boys perfectly, keeping everything in place - CHAFE-REDUCING BOXERS FOR MEN - ideal for guys with thinner legs, the unique Ultraglyde panel technology by the geniuses at Step One helps prevent ride up and those awkward re-adjustment moments with your hands down your underpants - KEEPS YOU COOL & FRESH - the moisture wicking viscose made from bamboo underwear removes sweat keeping you cool and dry at all times, no more stickiness in your underwear trunks when you're playing sport, working out or chilling in the sun - DESIGNED IN AUS - to keep you looking and feeling good down under, Step One boxers are ethically made with Bamboo viscose fabric so it's just as good for the world as it is for your behind ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0DTTS16GS | | Age Range Description | Adult | | Apparel Fabric Stretch | Medium Stretch | | Apparel Fabric Weight Class | Lightweight | | Best Sellers Rank | 12,528 in Fashion ( See Top 100 in Fashion ) 35 in Men's Underwear Trunks | | Bottom Style | Trunks | | Brand Name | STEP ONE | | Care instructions | Machine Wash | | Colour | Black | | Country Of Origin | China | | Country of origin | China | | Customer Reviews | 4.5 out of 5 stars 2,894 Reviews | | Fabric Type | 95% Bamboo Viscose and 5% Spandex | | Fit Type | regular | | Fit to Size Sentiment | Fit well | | Garment Size Country | Australia | | Global Trade Identification Number | 09360941000172 | | Item Type Name | Trunks | | Manufacturer | Step One | | Material Type | Bamboo Viscose, Spandex | | Material composition | 95% Bamboo Viscose and 5% Spandex | | Number of Items | 1 | | Pattern | Solid | | Product Care Instructions | Machine Wash | | Rise Style | Mid | | Size | S | | Special Features | Anti Chafe, Breathable, Lightweight, Moisture Wicking | | Style Name | Modern | | Unit Count | 1.0 count | ## Images ![– Mens Underwear Trunk Briefs, 1 Pair, Underwear for Men, Moisture Wicking, 3D Pouch + No Ride Up Trunk Briefs for Men - Image 1](https://m.media-amazon.com/images/I/61D7PhedxPL.jpg) ## Available Options This product comes in different **Color, Size** options. ## Questions & Answers **Q: What is the first pair promise?** A: We are so confident you'll love your Step One underwear; we'll reimburse your first pair if you don't like them for any reason - even if you've already tried and worn them! **Q: Where are Step One's designed?** A: All our underpants are designed at Step One HQ in Sydney, Australia, and ethics are at the forefront of every decision made here at Step One, from the Sydney office to the bamboo forests. **Q: How do I care for my Step Ones?** A: We recommend a cold machine wash with a gentle soap to best maintain the integrity of the organic bamboo fabric.

Nay—a man rebottomed. These trunks are a triumph. The fabric? Soft as angel gossip. The fit? Snug but not strangling—like being lovingly cupped by a team of retired Swiss butlers. Colour-wise: blue. Not “corporate Zoom shirt” blue, not “haunted swimming pool” blue—no, this is the blue of confidence. The blue of a man who knows where his keys are and remembers bin day. A leader. A legend. Washing? They survive our hard-water, toddler-wrath laundry cycles like grizzled veterans. No sag, no fade, no spontaneous unraveling in public. To conclude: these trunks turned my husband into a Greek statue with Wi-Fi access. Would buy again. Already did. Might buy more, just in case society collapses and we must rebuild civilization with well-panted men. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/738054348-mens-underwear-trunk-briefs-1-pair-underwear-for-men-moisture](https://www.desertcart.jp/products/738054348-mens-underwear-trunk-briefs-1-pair-underwear-for-men-moisture) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-10-17*
