๐ฅ Jiu-Jitsu Rashguard – From Beginner to Review, Plus Today’s Little Incident
Hello~ I’m Seojun from Cheongju! ๐
Today I want to share something a bit special.
It’s about… “jiu-jitsu rashguards.”
Actually, I’m writing this because of… a small incident that happened today.
And at the same time… it’s also the day a long-held wish of mine came true.
โ Jiu-Jitsu Rashguard? What’s That?
When I first started jiu-jitsu, I honestly didn’t know either.
“I can just wear comfortable workout clothes, right?” That thought… was really naive ๐
But the gym instructor said
wearing a rashguard reduces discomfort from movement and
friction during training.
After actually rolling on the gym floor,
scrambling with opponents a few times,
and getting drenched in sweat, I realized one thing.
“Rashguards are really necessary.”
Jiu-jitsu rashguards aren’t just simple t-shirts.
โ๏ธ They protect your skin
โ๏ธ Shield your body from opponents’ nails, sweat, and friction
โ๏ธ Most importantly, they fit snugly during training to help you perform at your best
โ What Have I Been Wearing Until Now?
Up until now, I’ve mainly worn Under Armour compression for jiu-jitsu.
Under Armour is actually a great brand for the gym.
The sweat absorption, tightness, and fit were all satisfying.
But… the problem is…
“Under Armour isn’t a jiu-jitsu-specific rashguard” ๐
Generally, when you wear Under Armour for grappling…
โ๏ธ It’s weak against friction
โ๏ธ After rolling a few times, seams start coming loose
โ๏ธ The top gets pilled
Despite all that…
I’ve managed to make my Under Armour clothes last for years
with “extreme control” lol ๐
โ And Today… A Disappearance Occurred ๐ฑ
Today, as usual, I finished my gym workout and went to shower.
I left my Under Armour top and compression shorts on the bottom of my locker and headed straight to the shower~
And when I got home…
Wait… “Uh…? Why are my clothes missing…???”
My mind went blank… ๐จ
โ๏ธ Did someone take them by mistake?
โ๏ธ I thought I packed them properly…
โ๏ธ Or did I put them in my new bag?
It’s still a mystery…
“The Case of Seojun’s Missing Under Armour”…
The truth might still be somewhere on the gym floor… ๐
โ So… I Ended Up Buying Again ๐๐ฅ
No time to be sad… the next day I immediately logged onto Coupang!

โ And… My Wish Finally Came True… “Spider Rashguard” ๐ญโค๏ธ
This is actually a really big personal change for me.
‘Spider Rashguard’
That brand I occasionally saw at the gym since I was young…
“Will I ever be able to spar wearing Spider?”
Those days when I could only look at it from afar…
There’s even a Spider rashguard photo on my vision board…
But this time, finally…
Spider top and bottom full set, about 160,000 won investment!!
Honestly, in terms of money, it’s quite a big expense for me. ๐
But…
Even as I write this…
“Yeah… I’ve grown… Now I’m someone who wears Spider…”
“The value of my wish fulfilled with 160,000 won… definitely worth it…”
That sense of pride washes over me ๐ญโจ
โ Spider Rashguard Advantages (Purple Belt Seojun’s Perspective ๐)

โ๏ธ Top-tier durability (for this price range)
โ๏ธ Solid stitching
โ๏ธ Allows quick movement, harder for opponents to grab (my theory)
โ๏ธ Clean design, logo not excessive
โ๏ธ One-piece bottoms prevent riding up
โ๏ธ Best performance for the price
โ๏ธ Can trap opponents like a spider (Spider buff)
โ Spider Disadvantages (Honest Version ๐)
โ๏ธ Lacks name value compared to top international brands
โ๏ธ A bit difficult to wear to the gym
โ๏ธ Design preferences vary by person
โ๏ธ Almost no recognition overseas

โ When I Went to the Gym in Under Armour… That Legendary Reaction Compilation (Seojun’s Theory) ๐โจ

Beginners: Scary… (who am I?)
โ๏ธ Beginners’ reactions:
๐ “Whoa… Under Armour? Is that guy… a powerhouse…?”
๐ “Those muscles in Under Armour? …How much does he lift at the gym…”
๐ “He’s slim but… why does he look so solid…?”
๐ “What’s this pressure…? Doesn’t seem like the same weight class…”
๐ “I have to face… that guy today…? ๐จ”
โ๏ธ Teammates’ reactions (inner thoughts lol):
๐ “Seojun… wearing Under Armour again lol”
๐ “But his performance lately is insane…
He’s about to hit 500 on the big 3, right?”
๐ “Just wearing Under Armour… but what’s with that physicality pinning people on the mat…”
๐ “When I’m losing during sparring… I feel even more intimidated…
Because… it’s the first time someone in Under Armour
has dominated like this… lol”
โ๏ธ Sometimes quietly whispering in the back:
๐ “Why does that guy still only wear Under Armour…
But… he’s scary…”
๐ “That’s not… Under Armour, it’s just… a power aura…”
โ Seojun’s Words ๐โค๏ธ
“It’s not about the gear,
it’s about how hard you train in it
and what story you build…”
I, Seojun,
have been doing jiu-jitsu and MMA in Under Armour all this timeโจ
But…
Sometimes the joy of buying and wearing clothes you’ve wanted…
That’s… such a precious reward… ๐ญโค๏ธ
Thank you for reading!
Seojun is still growing today and tomorrow!
Love you all…!! ๐ขโจ
