YOGA
Mountain Training: Fabric and Fit Notes
February 20, 2024 · Alo Editorial · 2 MIN READ

What yoga in the mountains asks for is unglamorous: handling a temperature swing. Here is how to check the fit before you commit. This breaks down what to look for and what you can safely ignore.
Treat yoga in the mountains as a fit problem before a style problem. The sports bra either handles handling a temperature swing or it does not, and no layering fixes the second case. Everything here is checkable in a mirror in under two minutes.
Where the sports bra carries the load
In yoga in the mountains, the sports bra does more work than anything else you put on. The band does most of the work, so it should sit level and snug before you even look at the straps. Everything else in the outfit is secondary to that.
Band and cup are independent. If the band rides up, the band is too big regardless of how the cup feels, and most people then fix the wrong one.
One rule that settles it when you train in the mountains
Use this rule: if the sports bra passes handling a temperature swing, buy it; if it only works with a specific layer or a specific temperature, skip it.
The practical constraint is simple: the same session can start cold and finish warm, or the other way round. Plan around it and most of the other decisions make themselves.
Care that actually extends the life
Do not store anything damp. Most odour problems are storage problems: the same session can start cold and finish warm, or the other way round.
If you are choosing between two that both fit, take the one that still works when the plan changes. Sessions rarely go exactly as intended.
What to check before you buy when you train in the mountains
Two pieces can look identical on the hanger and behave differently in the mountains. The checks below are the ones that catch it early. Bone Alosoft High-Waist 7/8 Highlight Legging is the piece we would test them against first.
- Squat test in a mirror: the fabric should go opaque, not sheer.
- The waistband should sit flat at your natural waist without rolling when you fold forward.
- Check the inseam against your height — a 7/8 length on a tall frame is a crop.
What to confirm before you go
Write the list down once and stop re-deciding. The items that matter for handling a temperature swing do not change from week to week.
Keep it simple. One sports bra that handles handling a temperature swing, one layer, and a rotation that lets everything dry.
FREQUENTLY ASKED QUESTIONS
- How do I know if the fit is right?
- Check it through a full range of motion and again seated: The band does most of the work, so it should sit level and snug before you even look at the straps.
- What fabric weight should I choose?
- Mid-weight for most of the year. Go lighter when handling a temperature swing means heat, denser when you start cold. Most people solve it by buying more, which is rarely the actual answer.
- When should I replace it?
- When the underbust seam stops holding, or the fabric no longer returns to size. Check it in a mirror in the position you will hold, not standing straight.
