Recent Base Layer Bottom Reviews

Avalanche Wear Mogul Pant

rated 1 of 5 stars These used to be my go-to pants. They were fantastic until they changed the fabric years ago and made them in China. I just bought these pants after years of refusing to buy them for years because of the terrible pilling and their latest product is worse than ever. They pilled immediately. I bought Athletica Polartec at the same time and there is no pilling. I am so disappointed because 15 years ago when they were made in Canada they were fantastic. Why don't companies listen to their consumer reviews? Full review

Coldpruf Platinum II Pant

rated 5 of 5 stars ColdPruf has better quality materials (not cotton) than the old stuff I have, and the fit is much better. There are excellent sizing charts and sizes for tall people, like myself. The fit is great. I could comfortably play sports or other activities in the Platinum II without any range of motion restrictions. It is tight enough fitting for a base layer (the modern name for long underwear), but not too tight. Recommend for active people in cold weather. As a member of another website, I get products… Full review

Ridge Merino Inversion Midweight Bottoms

rated 4.5 of 5 stars These high quality, high performance mid-weight base layer bottoms perform without adding unnecessary bulk! Unrestrictive and warm, Ridge’s new base layer line is ideal for people who have an active outdoor lifestyle. Whether skiing, backpacking, or even doing outdoor chores, the merino wool Inversion will help regulate temperature regardless of the conditions! A winter afternoon walk with Otto SPECS 18.5 micron merino wool 190g weight UPF 50+ 100% recycled polyester waistband Flatlocked seams… Full review

Avalanche Wear Women's Mogul Fleece Legging

rated 5 of 5 stars Where I live temperatures can drop well below zero I have never even thought about wearing a second pair of pants. The inner fleece lining is super soft and wicks moisture away from your skin also blocks wind. Washes well without breaking down. I've had my pair for two years and they're still my go-to winter running pants. Stretch as well when running. I have the woman's version of these pants, but could not find them on the site and wanted to express how much I truly love these pants. Full review

Terramar Men's Silk Pant

rated 2 of 5 stars Great pajamas, poor base layer. Thermasilk base layer from Terramar is not adequate for outdoor sports or any type of physical activity: It is far too weak and fragile. It is too thin to provide any warmth, and when wet, they feel cold. They will rip and shred if worn in an endurance sports or hard work setting. Also, they do not hold their shape. Hand-washing brings back their original shape, but they become limp after a couple of days out in the field. On the other hand, they make the best pajamas,… Full review

Patagonia Men's Capilene Lightweight Bottoms

rated 4.5 of 5 stars Go-to sleeping bottom. These are my go-to sleeping bottoms.  They're light enough to wear in the summer, provide a good base layer for the winter, and are more comfortable than laying directly on nylon or whatever. I've never gotten them wet but assume they would dry fast. They fit well, and have a functional fly. One extra chilly day I hiked most of the morning in them before I noticed the micro grid pattern on the inside was causing chafing. Wouldn't recommend putting miles in with these. Great… Full review

Ibex Men's Woolies 2 Bottom

rated 5 of 5 stars My butt always froze on a wet ski lift—until these. These rock—no problems after 9 years. Very comfortable and never overheating thanks to the way merino regulates temperature. Wool keeps you warm even when wet. Never gotten moist from sweat, wicks well. Still looks new, quality durable construction. Full review

Patagonia Men's Merino Air Bottoms

rated 5 of 5 stars The Patagonia Merino Air Bottoms exceeded my expectations. Game changing merino-synthetic fabric with no seams and effortless stretch. Material that breathes, holds heat, and moves water away from your skin as you heat up. Patagonia is one of the companies that other brands hate and simultaneously wish they could be.  The Merino Air Bottoms are made from recycled polyester and merino wool (the stuff men's suits are made of) grown in Patagonia.  I used to think that no single baselayer material… Full review

Avalanche Wear Mogul Pant

rated 5 of 5 stars Most comfortable pants EVER. Bought a pair of these last week and I really don't want to wear anything else now. The fit is excellent and form flattering. The outer material is smooth polyester and seems to block wind as a previous reviewer mentioned. The inside is soft cozy fleece. Not sure if the waistband has elastic or what, but it is padded for comfort and hugs your waist without pinching at all. The zip pocket is a great size and large enough to carry credit cards, tissues, lip balm, etc. Full review
