Off to your next microadventure! The heart of your bikepacking gear, the ORTLIEB Seat-Pack, is easily mounted to the seatpost with extra-strong Velcro straps. A practical bonus: the saddlebag also serves as a mudguard off-road. The spacious, waterproof Seat-Pack reliably keeps your clothes dry. The bag's volume can be cleverly adjusted between 8 and 16.5 liters or between 4.5 and 11 liters by tightening the roll-top closure on the sides, depending on the length of your trip. An additional valve allows for quick and easy compression and even greater compactness. For a day trip, the Seat-Pack is ideal as a backpack alternative, whether you're riding a cross bike, mountain bike, road bike, or e-mountain bike. The bag is available in two sizes. A mounting height of six centimeters on the seatpost is sufficient for the smaller of the two bags, therefore the more compact version is ideal for smaller frame sizes, full-suspension bikes and bikes with a dropper seatpost.

Just buy them
Color: Black,navy,burgundy,brown, Size: Small
Used to wear sliders all the time, figured i'd switch it up. These are super comfortable, probably the best material underwear I own. Great to just lounge around it or wear everyday. Fit is really good, I got a small and about 29-30" waist. Good bang for your buck too. I've washed them a handful of times and they hold up great, fit great and dont' shrink.

Good underwear. Husband likes them.
Color: Black, Size: Large
Husband wears XL and XL fit well. This is the second pack I got for him. They are decent quality, look and feel nice, not baggy yet not too tight anywhere. They are somewhat thin (but still supportive) and do not make him sweat more so he loves that. No problems washing (they didn’t shrink). Will continue to repurchase these.

Comfortable
Color: Black,navy,burgundy,brown, Size: Medium
I have had a lifetime of different briefs, some name brand, some generic. I am 165 lbs, wear Medium, and these are closest to feeling commando of anything I’ve ever worn. Comfortable, not too tight waist and legs, and yes silky touch yet not slinky. Maybe not for support wear, but casual and cool comfort, the “Cat’s meow”. I just came on to order some more

Great fabric - pouch too small!
Color: Black, Size: X-Large
First, the fabric used is wonderfully soft and comfortable. It;s the first thing noticed when package was opened. Strange, but the elastic waistband is about 1/2", very similar to a woman's style panty. But it's comfortable and easily acceptable. The main problem is that the pouch that holds your "stuff" in place, is oddly and unnaturally small. Small enough where this average man's "stuff" tends to fall out of the pouch on one side or the other. I sleep in my underwear, and every time I did with these, I awoke with the front pouch off to the side and everything down there was hanging outside of the underwear. They also seem to do well through a wash cycle. However, if the main reason for wearing underwear is to keep your stuff in place, these fail from the beginning. I ordered another brand from overseas, and they had the exact same problems as these! I wonder if that's just how they make them outside of the USA. The Bottom Line? Uncle Steve Disapproved!

Premium cotton underwear at a modest price. Highly recommend!
Color: Multicolora6-4 Pack, Size: X-Large
Bought my husband 2 variety packs of these, and they are still great over 2 years in. High quality cotton briefs are breathable, colors are vibrant, and the fit is spot on. A good value at this price point compared to designer brands, and the product overall exceeds expectations in terms of comfort level, durability and appearance.
