How we evaluate gear
SleeveShirts is an independent affiliate guide, not a manufacturer, testing lab, medical provider, or large editorial team. This page explains how we research and organize recommendations so readers can understand what is evidence-backed, what is editorial judgment, and what should be treated as a product claim.
The short version
We are not a laboratory
We do not claim to run certified UPF, chemical, abrasion, or spectrometer tests unless an article explicitly says an item was personally inspected and how.
We compare evidence
We use manufacturer specifications, independent reviews, standards guidance, pricing, availability, and buyer feedback patterns.
We disclose incentives
Some links are affiliate links. We may earn from qualifying purchases, but the buyer pays the same price.
What we evaluate
UPF and coverage
We prioritize clearly stated UPF ratings, coverage area, hood and sleeve design, and whether the brand explains the protection standard behind the claim.
Fabric and breathability
We compare fiber type, weave, GSM where available, stretch, venting, moisture handling, and whether the garment is built for heat, water, trail, or casual use.
Fit and use case
We separate recommendations by actual use: fishing, hiking, running, travel, golf, kids, women-specific fit, budget picks, and broad everyday protection.
Durability signals
We look for construction details such as stitching, cuffs, hood shape, thumbholes, abrasion zones, care requirements, and repeated complaints in user feedback.
Price and availability
We favor products that are easy to find, reasonably priced for their feature set, and practical for shoppers using Amazon or major outdoor retailers.
Evidence quality
We separate manufacturer claims, third-party review data, user feedback, standards-based claims, and our own editorial judgment instead of treating them as the same thing.
Sources we use
- Manufacturer specifications and product pages
- Published UPF, SPF, textile, and dermatology guidance where relevant
- Independent reviews from outdoor and gear publications
- Amazon listings, availability, pricing ranges, and buyer feedback patterns
- Brand documentation for fabric technologies and care instructions
- Hands-on editorial inspection only when we actually have access to an item
What we do not claim
- We do not claim to be dermatologists or medical professionals.
- We do not claim every product was physically tested by us.
- We do not claim to run certified laboratory testing.
- We do not guarantee product prices, availability, ratings, or seller quality.
- We do not treat Amazon reviews as proof; we use them as one weak signal among several.
How to read older articles
Some older SleeveShirts articles use stronger wording such as "tested," "research team," "lab," or "field test." Going forward, those phrases should be read conservatively unless the article gives a specific method. We are updating older content to distinguish between hands-on inspection, manufacturer specifications, published research, third-party reviews, and editorial synthesis.
Affiliate and editorial separation
SleeveShirts may earn commissions from Amazon links. Our goal is to make the recommendation process transparent enough that you can disagree with a pick and still understand why it appeared. For product decisions with health or safety consequences, use our content as a starting point and consult qualified medical or safety guidance when needed.
