Marmot Men's Uptrail Active Tank Top (Spring 2026) in Boulder Crack Map Camo

Owners report Marmot fits true to size overall, with the rain pants and some bottoms running slightly roomy.

On the core jackets, retailer fit data is one-sided: every Zappos sizing respondent for the PreCip rated it true to size, with owners noting room for a light layer underneath and some deliberately going up a size only to fit bulky mid-layers. Sizing-guide roundups agree that Marmot jackets typically run true to size and track other American outdoor brands. The soft spot is bottoms: CleverHiker's PreCip Eco rain pants review says the fit runs slightly big and suggests sizing down, and owner feedback on shorts and sweatpants echoes a somewhat generous cut. Cuts also skew trimmer on athletic-fit styles, so per-item reviews are worth a glance on slim-labeled pieces.

Sizing advice: Order your usual size in jackets and tops (go up one only if you layer heavily); consider sizing down in the rain pants and other roomy bottoms.

Reviewers who put Marmot's AirFleece fleece top through extended trail and daily wear report it holds up well: one tester found "no pulled threads or annoying loop snags" after bushwhacking through dense, thorny vegetation, and another noted no pilling "even in high contact areas like the underarms or sides" after weeks of regular wear. The fit runs true to size with a slightly relaxed cut, and testers single out the softness, likening the jacquard-grid fleece to a chenille-like texture. It performs best as a light layer in cool weather (50s-60s); testers note wind can cut through it faster than a heavier fleece, so it isn't meant as standalone protection in colder or gustier conditions.

Strengths

Reviewers consistently praise the fleece's softness and its resistance to pilling and snagging even after heavy trail use.

Watch out for

The lightweight, breathable knit isn't very wind-resistant, so testers recommend layering it under a shell in colder or gustier conditions.

Sizing

One reviewer found it fit true to size in their usual size, with sleeves long enough to bunch comfortably at the wrist.
