Thermal compression tights praised for exceptional warmth and storage. Customers said the "360-degree waistband is a game changer" and material is "buttery soft perfection." Excellent for sub-freezing runs. However, fit issues noted: crotch sits too low/long, causing bunching; length inconsistent. Some found sizing challenging between small and medium.

Wanted to try for myself

I've read the other reviews but wanted to see for myself. I don't have an issue with the length. They come down to around my ankles. I would not call them cropped. The proportions are definitely off a little. The crotch is a little long. If they pulled crotch up an inch and added the length to the legs they would be much better. I love the storage. They are fine for running from 25deg to 35deg. I do run cold. So take that into account. I live in NH and wear as little as possible when I run outside to keep the sweat down and the chill away. I would recommend giving them a try and not just basing it on the reviews. I'm.going to buy two more pairs.

Strange Fit, good colors and pocket setup

First off, I have the Men's Compression Ouray and regular half tights and they've been a solid performer on runs for me. I thought the Alpine thermals and ultimate thermals would provide the same performance . While I think the material finish, pockets, and color choices are excellent, I feel these tights don't fit right in several areas. Since I wear small in the half tights, I bought both small and medium in the full tights. The smalls felt OK at the waist but came up well short of my ankles. While the mediums felt a little longer, the high waist and bunching of material at the crotch made these tights unworkable for me. The seamless seat area feels like it sits too high on the waist and doesn't provide the right freedom of movement around the crotch. I feel like maybe a separate panel for the crotch would allow the tights to move more independently. Additionally, maybe a regular and a long length would help for taller users as a 24 or 25 inch Inseam is too short for coverage on people with longer legs, especially in cold weather. As I said before, I really do like the color choices, it really branches out from a bland black or dark gray colors of other brands. Fix the fit and I'll buy these again next season!

Toasty Warm and Extremely Comfortable

I finally found a pair of winter tights that actually stay put and hold everything I need. The 360-degree waistband is a game changer—I can fit my phone, keys, and several gels without any annoying bounce. The 280gsm thermal fleece is perfect for sub-freezing temps; it keeps my muscles warm without causing me to overheat during high-intensity intervals. If you're tired of carrying a separate running belt over your tights, these are exactly what you need.

Terrible Fit

I own 4 pairs of FlipBelt running shorts and I've been quite pleased with them. I therefore asked my wife to buy me a pair of these thermal pants for cold weather running as a Christmas gift. I was very disappointed to find that they didn't fit AT ALL like the shorts. The crotch hung 5 inches low, bunching the fabric between my thighs. To get the crotch up to the right height, the waistband had to be pulled up to my rib cage.

Sadly, I had removed the tags with the assumption that they would fit like the shorts, and now FlipBelt will not accept a return or exchange. I definitely should have tested them first, because I'm now stuck with a very expensive shop rag.

Winter Trail Run Ready!

This thermal thighs is very useful. I used this on 37-40F trail run training, and never felt the chill air coming inside my lower legs. Prepping for Woodside Ramble 50K Trail in Redwood City CA on 12/20/25. I will definitely, highly, super recommend this!

Perfect For Those Cold Days

I hate being cold on my runs and these make sure my legs stay nice and toasty the entire time. I love having all the pockets to hold my phone and gels and if I warm up I have spots to put my gloves or beanie. They are perfect to get me through my winter runs!
