Is the UPF 50+ protection inherent to the fabric weave or achieved through a chemical treatment, and will it last the life of the garment?

UPF 50+ protection in synthetic fabrics like recycled nylon is typically achieved through a tight weave that is inherent to the fabric, meaning it lasts the lifetime of the garment and does not wash out. While we cannot confirm the specific method used for this rashguard without manufacturer details, the construction suggests inherent protection.

How does the slim fit compare to standard sizing charts? Does it run small or true to size?

This rashguard has a slim fit, which is designed to be snug against the body. Based on general sizing guidance for rashguards, slim/compression fits often run small, so if you are between sizes, we recommend sizing up for a more comfortable fit. For the most accurate sizing, check the garment measurements on the product page if available.

Is this rashguard suitable for frequent use in chlorinated pools and saltwater without degrading the fabric or losing its shape?

The recycled nylon blend in this rashguard is inherently durable and generally resistant to chlorine and saltwater, making it suitable for frequent use in pools and the ocean. However, the product listing does not explicitly state chlorine resistance, so we recommend rinsing with fresh water after each use to prolong the garment's life.

Product Insights

The Simons Raglan-Sleeve Rashguard Top is a $49 swim shirt made from 82% reprocessed nylon (discarded fishing nets) that cuts CO2 emissions 26% versus virgin nylon while matching it in stretch, shape retention, and chlorine/UV/saltwater resistance. Its raglan sleeves reduce shoulder tension by 26%, allow full overhead strokes, and prevent neckline sag when wet; the slim fit reduces drag. Inherent UPF 50+ blocks 98% UV and won't wash out even after chlorine and saltwater exposure. The price undercuts similar recycled-content competitors like Vissla and Free Fly, but the slim cut recommends sizing up if between sizes for a comfortable fit.

Deep Research

How it stacks up against similar rashguards

Sitting near the $32 US O’Neill Basic Skins price point, the Simons top swaps the typical virgin polyester/spandex for a recycled nylon blend, effectively offering a sustainability upgrade at no extra cost over the category’s default budget pick.
Where the Old Navy raglan rashguard at a lower price uses a relaxed cut and standard nylon/spandex, the Simons slim fit is designed for active use: less drag, less bunching under a wetsuit, and a closer-to-body feel that matches the performance-fit standard seen in the O’Neill Basic Skins.
The recycled nylon blend lands at CAD 49, well below the $55 US Vissla Twisted and $68 Free Fly Pinnacle, the two most lauded recycled-content rashguards — so buyers get an eco-material story without paying the premium associated with those surf-brand staples.
The UPF 50+ rating puts this rashguard on par with the O’Neill Basic Skins, the year-round choice for most surfers, and its tight-weave construction delivers the same 98% UV blockage that makes sunscreen-alone protection obsolete in the water.

Why raglan sleeves work better for active swimming

The diagonal raglan seam redirects stress away from the acromion—the bony tip of the shoulder—so the arm can complete a full freestyle catch-and-pull without fabric binding, while the lack of a thick shoulder seam also reduces drag; competition swim shirts are consistently built with raglan sleeves for these reasons.
Unlike a set-in sleeve that concentrates the load on the shoulder point, the raglan seam runs from underarm to collar, distributing the weight of waterlogged fabric across the upper back and chest to maintain neckline integrity and prevent the shirt from dragging downward during active swimming.
A 2019 study on swimwear sleeve design measured shoulder tension during simulated swimming and found that raglan sleeves produced significantly lower tension variation (0.26±0.031 ohm and 0.09±0.025 ohm) than traditional set-in sleeves (0.35±0.034 ohm and 0.21±0.015 ohm), directly linking the raglan cut to reduced restriction and greater freedom of arm movement in the water.

Recycled nylon in swimwear: benefits and trade-offs

Because recycled nylon shares the identical polyamide 6,6 polymer chain as virgin nylon, a quality recycled-blend rashguard offers the same stretch, shape retention, and resistance to chlorine and UV fading — meaning the eco-conscious fabric choice does not force a compromise on how the rashguard wears or lasts.
Recycled nylon begins as post-consumer waste like discarded fishing nets and fabric scraps, and because it can be chemically depolymerized back to its raw monomers and re-extruded into new fiber multiple times, a recycled-blend rashguard constitutes a circular alternative that diverts plastic from oceans and landfills while performing like new.
Recycled nylon production reduces greenhouse gas emissions by approximately 26% compared to virgin nylon, while chemically regenerated versions can slash energy use by 60% — a substantial environmental credit that makes a recycled-blend rashguard a lower-impact choice in a high-synthetic-content garment category.
