Description

LTT Underwear is back with a brand new 1-pack in a wooly flavor! Famous for its breathability and comfort, this lightweight 50/50 Merino/Polyester blend underwear will help keep your undercarriage comfy and cool in the summer, and warm enough for a day outside in the winter.


Note for owners of existing LTT underwear: This Merino/Polyester blend has a more structured feel compared to our typical modal blend. Sizing has been adjusted to account for the new fabric, so if you wear a Medium in our existing underwear, you should still fit a Medium in these! As with all wool products, make sure to follow care instructions and avoid putting in the dryer to keep your underwear in tip top shape / avoid any potential shrinkage

Returns are only accepted for fully sealed, un-opened packs of underwear. If you have a concern with sizing after trying them on, please consult with our support team for further assistance.

Most comfortable underwear I've owned

This is a weird thing to say but... my junk gets uncomfortable easily. This underwear is far and away the most comfortable I've worn, and I've tried some weird/expensive options.

They're spendy so I bought one pair as a test run and loved them, then bought 3 more pairs with my last order. I would have bought more along with my precision driver order but the medium is out of stock. Restock mediums and I'll buy more.

Very comfortable. I hate how much I like them. I'm gonna end up buying so many

Simply lovely

This is easily the best underwear that I have ever worn. They are incredibly comfortable and breathable, making them great even in the warm weather. If they weren’t so expensive, I definitely would pick up more.

Best quality for the dollar

Was looking to update my drawers and was shopping around online to find what was better. Ended up trying some Duluth (~$24usd each) and SmartWool (~$48usd each). Shortly after LTT released this Merino model. While the price falls right between the 2 I previously bought the quality and comfort Is borderline tied with the SmartWool model and better than the Duluths. So for the $ spent I consider these the best of the 3. I have now bought 7 pairs if that adds any weight to my review.

(I have also tried the normal LTT boxer briefs, but the fit was slightly different in a way I wasn’t quite a fan)

The only suggestion I’d have would be maybe 2 more colorways.
