Love the Tech Hoodie!

Oh my goodness, I just got my Tech Hoodie and it's fantastic! The material feels super comfortable, and it looks really good. I wore it out yesterday and it kept me warm without feeling bulky. I'm already planning my next order, probably some Tech Shorts for summer. I'm telling all my friends about this place!

Good quality, consistent delivery

I've bought several items from Insider Store over the past year, mostly their Tech T-Shirts and Undershirts. This time I got a new Tech T-Shirt Gola V. The quality is always reliable, and it arrived in São Paulo in about 4 days, which is pretty standard for them. It's why I keep coming back.

Nice everyday socks

I ordered a pair of the Meia Invisível just to try them out. They arrived in about a week, which was fine. They're comfortable, fit well, and didn't slip down in my shoes. Nothing super fancy but they get the job done and seem like good quality for the price.

Are Insider Store's undershirts really that much better than, say, Basicamente or Lupo for anti-odor stuff?

D Donna M. 1 week ago
I switched from Lupo and the Insider ones are definitely superior for anti-odor and sweat. They feel way more premium too.

I haven't tried Basicamente, but compared to regular undershirts, Insider's anti-odor tech is no joke. I can wear them multiple times without them smelling funky. Big difference.

Can you use two discount codes at once? Like, if I have a free shipping code and a percentage off one?

J Jason W. 2 weeks ago
Nah, I tried that once and it didn't work. Their system only lets you apply one code at checkout. It's either or.

From my experience, no. They generally don't stack. Pick the better discount.

how easy are returns if something doesn't fit? do I have to pay for shipping back?

N Nancy Gomez 4 days ago
Returns were super easy for me. I just initiated it through their site and they sent a shipping label. Didn't have to pay anything.

B Barbara Lopez 2 days ago
Yeah, I returned a Tech Hoodie because the size was off. Process was smooth, they cover return shipping costs, I think for first exchanges/returns.

do the tech t-shirts really not wrinkle? i'm super skeptical about the 'no iron' claim.

H Hannah Robinson 1 month ago
Honestly, they're pretty legit. I pull mine straight from the dryer and it's good to go. Maybe a *tiny* crease if it sits wadded up for ages, but nothing like a regular cotton tee.

Can confirm. I travel a lot and just roll them up in my bag. Unpack, shake it out, and it looks fresh. It's a game changer.

what payment methods do they accept? can I pay with PayPal or just credit cards?

S Sam Hall 3 days ago
Pretty sure they take all major credit cards. I paid with my Visa without any issues. Not sure about PayPal, I don't remember seeing it.

A Amanda R. 3 days ago
I used a credit card. I think they primarily use standard card payments, but you'd have to check checkout for other options like PayPal or whatever.
